#include "[clang/Basic/SourceManager.h](SourceManager%5F8h%5Fsource.html)"

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.

◆ AllocateLoadedSLocEntries()

Allocate a number of loaded SLocEntries, which will be actually loaded on demand from the external source.

NumSLocEntries will be allocated, which occupy a total of TotalSize space in the global source view. The lowest ID and the base offset of the entries will be returned.

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.
