class | OverloadExpr |
class | ASTStmtReader |
Represents a C++ member access expression for which lookup produced a set of overloaded functions.
The member access may be explicit or implicit:
In the final AST, an explicit access always becomes a MemberExpr. An implicit access may become either a MemberExpr or a DeclRefExpr, depending on whether the member is static.
