Member Data Documentation

If this file has a #ifndef XXX (or equivalent) guard that protects the entire contents of the file, this is the identifier for the macro that controls whether or not it has any effect.

Note: Most clients should use getControllingMacro() to access the controlling macro of this header, since getControllingMacro() is able to load a controlling macro from external storage.

Definition at line 98 of file HeaderSearch.h.

Referenced by getControllingMacro(), clang::HeaderSearch::isFileMultipleIncludeGuarded(), isNonDefault(), mergeHeaderFileInfo(), and clang::HeaderSearch::SetFileControllingMacro().

The ID number of the controlling macro.

This ID number will be non-zero when there is a controlling macro whose IdentifierInfo may not yet have been loaded from external storage.

Referenced by getControllingMacro(), clang::HeaderSearch::isFileMultipleIncludeGuarded(), isNonDefault(), and mergeHeaderFileInfo().

DirInfo - Keep track of whether this is a system header, and if so, whether it is C++ clean or not. This can be set by the include paths or by #pragma gcc system_header. This is an instance of SrcMgr::CharacteristicKind.

Definition at line 49 of file HeaderSearch.h.

Referenced by clang::HeaderSearch::getFileDirFlavor(), clang::HeaderSearch::LookupFile(), clang::HeaderSearch::LookupSubframeworkHeader(), clang::HeaderSearch::MarkFileSystemHeader(), and mergeHeaderFileInfo().

Whether this header file info was supplied by an external source.

Definition at line 52 of file HeaderSearch.h.

Referenced by mergeHeaderFileInfo().

If this header came from a framework include, this is the name of the framework.

Definition at line 102 of file HeaderSearch.h.

Referenced by clang::HeaderSearch::LookupFile(), and mergeHeaderFileInfo().

Whether this header is part of the module that we are building. This is an instance of ModuleMap::ModuleHeaderRole.

Definition at line 62 of file HeaderSearch.h.

Referenced by getHeaderRole(), clang::serialization::reader::HeaderFileInfoTrait::ReadData(), and setHeaderRole().

Whether this is a header inside a framework that is currently being built.

When a framework is being built, the headers have not yet been placed into the appropriate framework subdirectories, and therefore are provided via a header map. This bit indicates when this is one of those framework headers.

Definition at line 75 of file HeaderSearch.h.

Referenced by clang::HeaderSearch::LookupFile(), and mergeHeaderFileInfo().

Whether this header is part of the module that we are building.
