class MacroDirective

Declaration

class MacroDirective { /* full declaration omitted */ };

Description

Encapsulates changes to the "macros namespace" (the location where the macro name became active, the location where it was undefined, etc.). MacroDirectives, associated with an identifier, are used to model the macro history. Usually a macro definition (MacroInfo) is where a macro name becomes active (MacroDirective) but #pragma push_macro / pop_macro can create additional DefMacroDirectives for the same MacroInfo.

Member Variables

protected clang::MacroDirective* Previous = nullptr
Previous macro directive for the same identifier, or nullptr.
protected clang::SourceLocation Loc
protected unsigned int MDKind
MacroDirective kind.
protected unsigned int IsFromPCH
True if the macro directive was loaded from a PCH file.
protected unsigned int IsPublic
Whether the macro has public visibility (when described in a module).
