Detailed Description

RecordDecl - Represents a struct/union/class. For example: struct X; // Forward declaration, no "body". union Y { int A, B; }; // Has body with members A and B (FieldDecls). This decl will be marked invalid if *any* members are invalid.

getDefinition - Returns the RecordDecl that actually defines this struct/union/class. When determining whether or not a struct/union/class is completely defined, one should use this method as opposed to 'isCompleteDefinition'. 'isCompleteDefinition' indicates whether or not a specific RecordDecl is a completed definition, not whether or not the record type is defined. This method returns NULL if there is no RecordDecl that defines the struct/union/tag.

isAnonymousStructOrUnion - Whether this is an anonymous struct or union. To be an anonymous struct or union, it must have been declared without a name and there must be no objects of this type declared, e.g.,

   union { int i; float f; };

is an anonymous union but neither of the following are:

  union X { int i; float f; };
  union { int i; float f; } obj;

Determines whether this declaration represents the injected class name.

The injected class name in C++ is the name of the class that appears inside the class itself. For example:

 struct C {
   // C is implicitly declared here as a synonym for the class name.
 };

 C::C c; // same as "C c;"
