Member Function Documentation

findPreprocessedEntitiesInRange()

virtual std::pair< unsigned, unsigned > clang::ExternalPreprocessingRecordSource::findPreprocessedEntitiesInRange ( SourceRange  Range )

pure virtual

Returns a pair of [Begin, End) indices of preallocated preprocessed entities that Range encompasses.

Implemented in clang::ASTReader.

isPreprocessedEntityInFileID()

virtual std::optional< bool > clang::ExternalPreprocessingRecordSource::isPreprocessedEntityInFileID ( unsigned  Index, FileID  FID  )

inlinevirtual

Optionally returns true or false if the preallocated preprocessed entity with index Index came from file FID.

Reimplemented in clang::ASTReader.

Definition at line 296 of file PreprocessingRecord.h.

ReadPreprocessedEntity()

virtual PreprocessedEntity * clang::ExternalPreprocessingRecordSource::ReadPreprocessedEntity ( unsigned  Index )

pure virtual

Read a preallocated preprocessed entity from the external source.

Returns

null if an error occurred that prevented the preprocessed entity from being loaded.

Implemented in clang::ASTReader.

ReadSkippedRange()

virtual SourceRange clang::ExternalPreprocessingRecordSource::ReadSkippedRange ( unsigned  Index )

pure virtual

Read a preallocated skipped range from the external source.

Implemented in clang::ASTReader.
