Public enums and private classes that are part of the SourceManager implementation. More...

Classes
class	ContentCache
	One instance of this struct is kept for every file loaded or used. More...
class	FileInfo
	Information about a FileID, basically just the logical file that it represents and include stack information. More...
class	ExpansionInfo
	Each ExpansionInfo encodes the expansion location - where the token was ultimately expanded, and the SpellingLoc - where the actual character data for the token came from. More...
class	SLocEntry
	This is a discriminated union of FileInfo and ExpansionInfo. More...
Enumerations
enum	CharacteristicKind { C_User, C_System, C_ExternCSystem }
	Indicates whether a file or directory holds normal user code, system code, or system code which is implicitly 'extern "C"' in C++ mode. More...
Functions
	static_assert (llvm::AlignOf< ContentCache >::Alignment >=8,"ContentCache must be 8-byte aligned.")

Enumeration Type Documentation

enum clang::SrcMgr::CharacteristicKind

Indicates whether a file or directory holds normal user code, system code, or system code which is implicitly 'extern "C"' in C++ mode.

Entire directories can be tagged with this (this is maintained by DirectoryLookup and friends) as can specific FileInfos when a #pragma system_header is seen or in various other cases.

Enumerator:

C_User
C_System
C_ExternCSystem
