Protected Member Functions

Resource * createImpl (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.

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.

ResourceHandle getNextHandle (void)

ManualResourceLoader * loader = 0,

const NameValuePairList * createParams = 0

) [virtual, inherited]

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.

Resource* Ogre::D3DTextureManager::createImpl ( const String & name,

ResourceHandle handle,

const String & group,

bool isManual,

ManualResourceLoader * loader,

const NameValuePairList * createParams

) [protected, virtual]

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.

Implements Ogre::ResourceManager.

TexturePtr Ogre::TextureManager::createManual ( const String & name,

const String & group,

TextureType texType,

uint width,

uint height,

int num_mips,

PixelFormat format,

int usage = TU_DEFAULT,

ManualResourceLoader * loader = 0

) [inherited]

Create a manual texture with a depth of 1 (not loaded from a file).

Parameters:

name The name to give the resulting texture

group The name of the resource group to assign the texture to

texType The type of texture to load/create, defaults to normal 2D textures

width,height The dimensions of the texture

numMipmaps The number of pre-filtered mipmaps to generate. If left to default (-1) then the TextureManager's default number of mipmaps will be used (see setDefaultNumMipmaps()). If set to MIP_UNLIMITED mipmaps will be generated until the lowest possible level, 1x1x1.

format The internal format you wish to request; the manager reserves the right to create a different format if the one you select is not available in this context.

usage The kind of usage this texture is intended for. It is a combination of TU_STATIC, TU_DYNAMIC, TU_WRITE_ONLY, TU_AUTOMIPMAP and TU_RENDERTARGET (see TextureUsage enum). You are strongly advised to use HBU_STATIC_WRITE_ONLY wherever possible, if you need to update regularly, consider HBU_DYNAMIC_WRITE_ONLY.

loader If you intend the contents of the manual texture to be regularly updated, to the extent that you don't need to recover the contents if the texture content is lost somehow, you can leave this parameter as 0. However, if you intend to populate the texture only once, then you should implement ManualResourceLoader and pass a pointer to it in this parameter; this means that if the manual texture ever needs to be reloaded, the ManualResourceLoader will be called to do it.

virtual void Ogre::TextureManager::enable32BitTextures ( bool setting = true ) [virtual, inherited]

Enables / disables 32-bit textures.

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 size_t Ogre::TextureManager::getDefaultNumMipmaps ( ) [virtual, inherited]

Gets the default number of mipmaps to be used for loaded textures.

Definition at line 235 of file OgreTextureManager.h.

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.

virtual size_t Ogre::ResourceManager::getMemoryBudget ( void ) const [virtual, inherited]

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

virtual size_t Ogre::ResourceManager::getMemoryUsage ( void ) const [protected, virtual, inherited]

Gets the current memory usage, in bytes.

Definition at line 338 of file OgreResourceManager.h.

ResourceHandle Ogre::ResourceManager::getNextHandle ( void ) [protected, inherited]

Allocates the next handle.

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 366 of file OgreResourceManager.h.
References Ogre::ResourceManager::ResourceMapIterator.

Gets a string identifying the type of resource this manager handles.

Definition at line 299 of file OgreResourceManager.h.
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.

TextureManager& Ogre::TextureManager::getSingleton ( void ) [static, inherited]

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< TextureManager >.

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.

void Ogre::D3DTextureManager::reloadAfterLostDevice ( void )

Restore the contents of all surfaces following a lost device.

virtual void Ogre::ResourceManager::reloadAll ( void ) [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.

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:
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 ( ResourcePtr & r ) [virtual, inherited]

Remove a single resource.

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 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::removeAll ( void ) [virtual, inherited]

Removes all resources.

Note:
The word 'Destroy' is not used here, since if any other pointers are referring to these resources, they will persist until they have been finished with; however to all intents and purposes the resources no longer exist and will 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::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 221 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.

Definition at line 216 of file OgreResourceManager.h.
References Ogre::SharedPtr< T >::isNull(), and Ogre::String.

virtual void Ogre::TextureManager::setDefaultNumMipmaps ( size_t num ) [virtual, inherited]

Sets the default number of mipmaps to be used for loaded textures, for when textures are loaded automatically (e.g.
by Material class) or when 'load' is called with the default parameters by the application. If set to MIP_UNLIMITED mipmaps will be generated until the lowest possible level, 1x1x1.
Note:
The default value is 0.

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.

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.
