Detailed Description
EnumDecl - Represents an enum. In C++11, enums can be forward-declared with a fixed underlying type, and in C we allow them to be forward-declared with no underlying type as an extension.

completeDefinition - When created, the EnumDecl corresponds to a forward-declared enum. This method is used to mark the declaration as being defined; it's enumerators have already been added (via DeclContext::addDecl). NewType is the new underlying type of the enumeration type.

| EnumDecl* clang::EnumDecl::getDefinition | ( | ) | const [inline] |
getDefinition - Returns the TagDecl that actually defines this struct/union/class/enum. When determining whether or not a struct/union/class/enum has a definition, one should use this method as opposed to 'isDefinition'. 'isDefinition' indicates whether or not a specific TagDecl is defining declaration, not whether or not the struct/union/class/enum type is defined. This method returns NULL if there is no TagDecl that defines the struct/union/class/enum.
