This class handles loading and caching of source files into memory.

This object owns the MemoryBuffer objects for all of the loaded files and assigns unique FileID's for each unique #include chain.

The SourceManager can be queried for information about SourceLocation objects, turning them into either spelling or expansion locations. Spelling locations represent where the bytes corresponding to a token came from and expansion locations represent where the location is in the user's view. In the case of a macro expansion, for example, the spelling location indicates where the expanded token came from and the expansion location specifies where it was expanded.

◆ getOrCreateFileID() ◆ getPreambleFileID() FileID clang::SourceManager::getPreambleFileID ( ) const inline ◆ getPresumedColumnNumber() ◆ getPresumedLineNumber() ◆ getPresumedLoc()

Returns the "presumed" location of a SourceLocation specifies.

getPresumedLoc - This method returns the "presumed" location of a SourceLocation specifies.

A "presumed location" can be modified by #line or GNU line marker directives. This provides a view on the data that a user should see in diagnostics, for example.

Note that a presumed location is always given as the expansion point of an expansion location, not at the spelling location.

Returns: The presumed location of the specified SourceLocation. If the presumed location cannot be calculated (e.g., because Loc is invalid or the file containing Loc has changed on disk), returns an invalid presumed location.

A "presumed location" can be modified by #line or GNU line marker directives. This provides a view on the data that a user should see in diagnostics, for example.

This computes the "presumed" location for a SourceLocation, then checks whether it came from a file other than the main file. This is different from isWrittenInMainFile() because it takes line marker directives into account.
