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 | // |
