Member Function Documentation

GetIdentifier()

virtual IdentifierInfo * clang::ExternalPreprocessorSource::GetIdentifier ( unsigned  ID )

pure virtual

Return the identifier associated with the given ID number.

The ID 0 is associated with the NULL identifier.

getModule()

virtual Module * clang::ExternalPreprocessorSource::getModule ( unsigned  ModuleID )

pure virtual

Map a module ID to a module.

Implemented in clang::ASTReader.

ReadDefinedMacros()

virtual void clang::ExternalPreprocessorSource::ReadDefinedMacros ( )

pure virtual

Read the set of macros defined by this external macro source.

Implemented in clang::ASTReader.

updateOutOfDateIdentifier()

virtual void clang::ExternalPreprocessorSource::updateOutOfDateIdentifier ( const IdentifierInfo &  II )

pure virtual

Update an out-of-date identifier.

Implemented in clang::ASTReader.
