ResourcecreateImpl (const String &name, ResourceHandle handle, const String &group, bool isManual, ManualResourceLoader *loader, const NameValuePairList *createParams)
 
Remarks:
Subclasses must override this method and create a subclass of Resource.
Parameters:
name The unique name of the resource
group The name of the resource group to attach this new resource to
isManual Is this resource manually loaded? If so, you should really populate the loader parameter in order that the load process can call the loader back when loading is required.
loader Pointer to a ManualLoader implementation which will be called when the Resource wishes to load (should be supplied if you set isManual to true). You can in fact leave this parameter null if you wish, but the Resource will never be able to reload if anything ever causes it to unload. Therefore provision of a proper ManualLoader instance is strongly recommended.
createParams If any parameters are required to create an instance, they should be supplied here as name / value pairs. These do not need to be set on the instance (handled elsewhere), just used if required to differentiate which concrete class is created.

Creates a new blank resource, but does not immediately load it.

Remarks:
Resource managers handle disparate types of resources, so if you want to get at the detailed interface of this resource, you'll have to cast the result to the subclass you know you're creating.
Parameters:
name The unique name of the resource
group The name of the resource group to attach this new resource to
isManual Is this resource manually loaded? If so, you should really populate the loader parameter in order that the load process can call the loader back when loading is required.
loader Pointer to a ManualLoader implementation which will be called when the Resource wishes to load (should be supplied if you set isManual to true). You can in fact leave this parameter null if you wish, but the Resource will never be able to reload if anything ever causes it to unload. Therefore provision of a proper ManualLoader instance is strongly recommended.

Creates a Bezier patch based on an array of control vertices.

Parameters:
name The name to give the newly created mesh.
groupName The name of the resource group to assign the mesh to
controlPointBuffer A pointer to a buffer containing the vertex data which defines control points of the curves rather than actual vertices. Note that you are expected to provide not just position information, but potentially normals and texture coordinates too. The format of the buffer is defined in the VertexDeclaration parameter
decaration VertexDeclaration describing the contents of the buffer. Note this declaration must _only_ draw on buffer source 0!
width Specifies the width of the patch in control points. Note this parameter must greater than or equal to 3.
height Specifies the height of the patch in control points. Note this parameter must greater than or equal to 3.
uMaxSubdivisionLevel,vMaxSubdivisionLevel If you want to manually set the top level of subdivision, do it here, otherwise let the system decide.
visibleSide Determines which side of the patch (or both) triangles are generated for.
vbUsage Vertex buffer usage flags. Recommend the default since vertex buffer should be static.
ibUsage Index buffer usage flags. Recommend the default since index buffer should be dynamic to change levels but not readable.
vbUseShadow Flag to determine if a shadow buffer is generated for the vertex buffer. See HardwareBuffer for full details.
ibUseShadow Flag to determine if a shadow buffer is generated for the index buffer. See HardwareBuffer for full details.

plane The orientation of the plane and distance from the origin
width The width of the plane in world coordinates
height The height of the plane in world coordinates
curvature The curvature of the plane. Good values are between 2 and 65. Higher values are more curved leading to a smoother effect, lower values are less curved meaning more distortion at the horizons but a better distance effect.
xsegments The number of segements to the plane in the x direction
ysegments The number of segements to the plane in the y direction
normals If true, normals are created perpendicular to the plane
numTexCoordSets The number of 2D texture coordinate sets created - by default the corners are created to be the corner of the texture.

vTile The number of times the texture should be repeated in the v direction
upVector The 'Up' direction of the plane.
orientation The orientation of the overall sphere that's used to create the illusion
vertexBufferUsage The usage flag with which the vertex buffer for this plane will be created
indexBufferUsage The usage flag with which the index buffer for this plane will be created
vertexShadowBuffer If this flag is set to true, the vertex buffer will be created with a system memory shadow buffer, allowing you to read it back more efficiently than if it is in hardware
indexShadowBuffer If this flag is set to true, the index buffer will be created with a system memory shadow buffer, allowing you to read it back more efficiently than if it is in hardware
ySegmentsToKeep The number of segments from the top of the dome downwards to keep. -1 keeps all of them. This can save fillrate if you cannot see much of the sky lower down.

Implements Ogre::ResourceManager.

MeshPtr Ogre::MeshManager::createManual const String name,
const String groupName,
ManualResourceLoader loader = 0
 

Creates a new Mesh specifically for manual definition rather than loading from an object file.

Remarks:
Note that once you've defined your mesh, you must call Mesh::_setBounds and Mesh::_setBoundingRadius in order to define the bounds of your mesh. In previous versions of OGRE you could call Mesh::_updateBounds, but OGRE's support of write-only vertex buffers makes this no longer appropriate.
Parameters:
name The name to give the new mesh
groupName The name of the resource group to assign the mesh to
loader ManualResourceLoader which will be called to load this mesh when the time comes. It is recommended that you populate this field in order that the mesh can be rebuilt should the need arise

void Ogre::MeshManager::createPrefabPlane void   )  [protected]
 

Real Ogre::MeshManager::getBoundsPaddingFactor void   ) 
 

Gets the factor by which the bounding box of an entity is padded.

Default is 0.01

virtual ResourcePtr Ogre::ResourceManager::getByHandle ResourceHandle  handle  )  [virtual, inherited]
 

Retrieves a pointer to a resource by handle, or null if the resource does not exist.

Retrieves a pointer to a resource by name, or null if the resource does not exist.

virtual Real Ogre::ResourceManager::getLoadingOrder void   )  const [virtual, inherited]
 

Gets the relative loading order of resources of this type.

Remarks:
There are dependencies between some kinds of resource in terms of loading order, and this value enumerates that. Higher values load later during bulk loading tasks.

Implements Ogre::ScriptLoader.

Retrieves whether all Meshes should prepare themselves for shadow volumes.

ResourceMapIterator Ogre::ResourceManager::getResourceIterator void   )  [inherited]
 

Returns an iterator over all resources in this manager.

Note:
Use of this iterator is NOT thread safe!

Definition at line 410 of file OgreResourceManager.h.

References Ogre::ResourceManager::ResourceMapIterator.

References Ogre::String.

virtual const StringVector& Ogre::ResourceManager::getScriptPatterns void   )  const [virtual, inherited]
 

Gets the file patterns which should be used to find scripts for this ResourceManager.

Remarks:
Some resource managers can read script files in order to define resources ahead of time. These resources are added to the available list inside the manager, but none are loaded initially. This allows you to load the items that are used on demand, or to load them all as a group if you wish (through ResourceGroupManager).
This method lets you determine the file pattern which will be used to identify scripts intended for this manager.
Returns:
A list of file patterns, in the order they should be searched in.

MeshManager& Ogre::MeshManager::getSingleton void   )  [static]
 

Override standard Singleton retrieval.

Remarks:
Why do we do this? Well, it's because the Singleton implementation is in a .h file, which means it gets compiled into anybody who includes it. This is needed for the Singleton template to work, but we actually only want it compiled into the implementation of the class based on the Singleton, not all of them. If we don't change this, we get link errors when trying to use the Singleton-based class from an outside dll.
This method just delegates to the template version anyway, but the implementation stays in this single compilation unit, preventing link errors.

Reimplemented from Ogre::Singleton< MeshManager >.

virtual ResourcePtr Ogre::ResourceManager::load const String name,
const String group,
bool  isManual = false,
ManualResourceLoader loader = 0,
const NameValuePairList loadParams = 0
[virtual, inherited]
 

Generic load method, used to create a Resource specific to this ResourceManager without using one of the specialised 'load' methods (containing per-Resource-type parameters).

Parameters:
name The name of the Resource
group The resource group to which this resource will belong
isManual Is the resource to be manually loaded? If so, you should provide a value for the loader parameter
loader The manual loader which is to perform the required actions when this resource is loaded; only applicable when you specify true for the previous parameter
loadParams Optional pointer to a list of name/value pairs containing loading parameters for this type of resource.

Reimplemented in Ogre::BspResourceManager.

MeshPtr Ogre::MeshManager::load const String filename,
const String groupName,
HardwareBuffer::Usage  vertexBufferUsage = HardwareBuffer::HBU_STATIC_WRITE_ONLY,
HardwareBuffer::Usage  indexBufferUsage = HardwareBuffer::HBU_STATIC_WRITE_ONLY,
bool  vertexBufferShadowed = true,
bool  indexBufferShadowed = true
 

Loads a mesh from a file, making it immediately available for use.

Note:
If the model has already been loaded, the existing instance will be returned.
Remarks:
Ogre loads model files from it's own proprietary format called .mesh. This is because having a single file format is better for runtime performance, and we also have control over pre-processed data (such as collision boxes, LOD reductions etc).
Parameters:
filename The name of the .mesh file
groupName The name of the resource group to assign the mesh to
vertexBufferUsage The usage flags with which the vertex buffer(s) will be created
indexBufferUsage The usage flags with which the index buffer(s) created for this mesh will be created with.
vertexBufferShadowed If true, the vertex buffers will be shadowed by system memory copies for faster read access
indexBufferShadowed If true, the index buffers will be shadowed by system memory copies for faster read access
priority The priority of this mesh in the resource system

MeshBuildParams params
[protected]
 

Utility method for manual loading a plane.

void Ogre::MeshManager::loadResource Resource res  )  [virtual]
 

See also:
ManualResourceLoader::loadResource

Implements Ogre::ManualResourceLoader.

virtual void Ogre::ResourceManager::parseScript DataStreamPtr stream,
const String groupName
[virtual, inherited]
 

Parse the definition of a set of resources from a script file.

Remarks:
Some resource managers can read script files in order to define resources ahead of time. These resources are added to the available list inside the manager, but none are loaded initially. This allows you to load the items that are used on demand, or to load them all as a group if you wish (through ResourceGroupManager).
Parameters:
stream Weak reference to a data stream which is the source of the script
groupName The name of the resource group that resources which are parsed are to become a member of. If this group is loaded or unloaded, then the resources discovered in this script will be loaded / unloaded with it.

Implements Ogre::ScriptLoader.

Reimplemented in Ogre::CompositorManager, Ogre::FontManager, and Ogre::MaterialManager.

virtual void Ogre::ResourceManager::reloadAll bool  reloadableOnly = true  )  [virtual, inherited]
 

Caused all currently loaded resources to be reloaded.

Remarks:
All resources currently being held in this manager which are also marked as currently loaded will be unloaded, then loaded again.
Parameters:
reloadableOnly If true (the default), only reload the resource that is reloadable. Because some resources isn't reloadable, they will be unloaded but can't loaded again. Thus, you might not want to them unloaded. Or, you might unload all of them, and then populate them manually later.
See also:
Resource::isReloadable for resource is reloadable.

virtual void Ogre::ResourceManager::reloadUnreferencedResources bool  reloadableOnly = true  )  [virtual, inherited]
 

Caused all currently loaded but not referenced by any other object resources to be reloaded.

Remarks:
This method behaves like reloadAll, except that it only reloads resources which are not in use, ie not referenced by other objects.
Some referenced resource may exists 'weak' pointer to their sub-components (e.g. Entity held pointer to SubMesh), in this case, unload or reload that resource will cause dangerous pointer access. Use this function instead of reloadAll allows you avoid fail in those situations.
Parameters:
reloadableOnly If true (the default), only reloads resources which can be subsequently automatically reloaded.

virtual void Ogre::ResourceManager::remove ResourceHandle  handle  )  [virtual, inherited]
 

Remove a single resource by handle.

Remarks:
Removes a single resource, meaning it will be removed from the list of valid resources in this manager, also causing it to be unloaded.
Note:
The word 'Destroy' is not used here, since if any other pointers are referring to this resource, it will persist until they have finished with it; however to all intents and purposes it no longer exists and will likely get destroyed imminently.

If you do have shared pointers to resources hanging around after the ResourceManager is destroyed, you may get problems on destruction of these resources if they were relying on the manager (especially if it is a plugin). If you find you get problems on shutdown in the destruction of resources, try making sure you release all your shared pointers before you shutdown OGRE.

virtual void Ogre::ResourceManager::remove const String name  )  [virtual, inherited]
 

Remove a single resource by name.

Remarks:
Removes a single resource, meaning it will be removed from the list of valid resources in this manager, also causing it to be unloaded.
Note:

virtual void Ogre::ResourceManager::remove ResourcePtr r  )  [virtual, inherited]
 

Remove a single resource.

virtual void Ogre::ResourceManager::removeAll void   )  [virtual, inherited]
 

Removes all resources.

Note:

Reimplemented in Ogre::CompositorManager.

virtual void Ogre::ResourceManager::removeImpl ResourcePtr res  )  [protected, virtual, inherited]
 

Remove a resource from this manager; remove it from the lists.

virtual bool Ogre::ResourceManager::resourceExists ResourceHandle  handle  )  [virtual, inherited]
 

Returns whether a resource with the given handle exists in this manager.

Definition at line 265 of file OgreResourceManager.h.

References Ogre::SharedPtr< T >::isNull(), and Ogre::ResourceHandle.

virtual bool Ogre::ResourceManager::resourceExists const String name  )  [virtual, inherited]
 

Returns whether the named resource exists in this manager.

void Ogre::MeshManager::setBoundsPaddingFactor Real  paddingFactor  ) 
 

Sets the factor by which the bounding box of an entity is padded.

virtual void Ogre::ResourceManager::setMemoryBudget size_t  bytes  )  [virtual, inherited]
 

Set a limit on the amount of memory this resource handler may use.

Remarks:
If, when asked to load a new resource, the manager believes it will exceed this memory budget, it will temporarily unload a resource to make room for the new one. This unloading is not permanent and the Resource is not destroyed; it simply needs to be reloaded when next used.

void Ogre::MeshManager::setPrepareAllMeshesForShadowVolumes bool  enable  ) 
 

Tells the mesh manager that all future meshes should prepare themselves for shadow volumes on loading.

void Ogre::MeshManager::tesselate2DMesh SubMesh pSub,
int  meshWidth,
int  meshHeight,
bool  doubleSided = false,
HardwareBuffer::Usage  indexBufferUsage = HardwareBuffer::HBU_STATIC_WRITE_ONLY,
bool  indexSysMem = false
[protected]
 

Utility method for tesselating 2D meshes.

virtual void Ogre::ResourceManager::unload ResourceHandle  handle  )  [virtual, inherited]
 

Unloads a single resource by handle.

Remarks:
Unloaded resources are not removed, they simply free up their memory as much as they can and wait to be reloaded.
See also:
ResourceGroupManager for unloading of resource groups.

virtual void Ogre::ResourceManager::unload const String name  )  [virtual, inherited]
 

Unloads a single resource by name.

Remarks:
Unloaded resources are not removed, they simply free up their memory as much as they can and wait to be reloaded.
See also:
ResourceGroupManager for unloading of resource groups.

virtual void Ogre::ResourceManager::unloadAll bool  reloadableOnly = true  )  [virtual, inherited]
 

Unloads all resources.

Remarks:
Unloaded resources are not removed, they simply free up their memory as much as they can and wait to be reloaded.
See also:
ResourceGroupManager for unloading of resource groups.
Parameters:
reloadableOnly If true (the default), only unload the resource that is reloadable. Because some resources isn't reloadable, they will be unloaded but can't load them later. Thus, you might not want to them unloaded. Or, you might unload all of them, and then populate them manually later.
See also:
Resource::isReloadable for resource is reloadable.

virtual void Ogre::ResourceManager::unloadUnreferencedResources bool  reloadableOnly = true  )  [virtual, inherited]
 

Unload all resources which are not referenced by any other object.

Remarks:
This method behaves like unloadAll, except that it only unloads resources which are not in use, ie not referenced by other objects. This allows you to free up some memory selectively whilst still keeping the group around (and the resources present, just not using much memory).
Some referenced resource may exists 'weak' pointer to their sub-components (e.g. Entity held pointer to SubMesh), in this case, unload or reload that resource will cause dangerous pointer access. Use this function instead of unloadAll allows you avoid fail in those situations.
Parameters:
reloadableOnly If true (the default), only unloads resources which can be subsequently automatically reloaded.
