| 32 | // SimpleContentModel is a derivative of the abstract content model base |
---|
| 33 | // class that handles a small set of simple content models that are just |
---|
| 34 | // way overkill to give the DFA treatment. |
---|
| 35 | // |
---|
| 36 | // DESCRIPTION: |
---|
| 37 | // |
---|
| 38 | // This guy handles the following scenarios: |
---|
| 39 | // |
---|
| 40 | // a |
---|
| 41 | // a? |
---|
| 42 | // a* |
---|
| 43 | // a+ |
---|
| 44 | // a,b |
---|
| 45 | // a|b |
---|
| 46 | // |
---|
| 47 | // These all involve a unary operation with one element type, or a binary |
---|
| 48 | // operation with two elements. These are very simple and can be checked |
---|
| 49 | // in a simple way without a DFA and without the overhead of setting up a |
---|
| 50 | // DFA for such a simple check. |
---|
| 51 | // |
---|
| 52 | // NOTE: Pass the XMLElementDecl::fgPCDataElemId value to represent a |
---|
| 53 | // PCData node. Pass XMLElementDecl::fgInvalidElemId for unused element |
---|
| 54 | // |
