Detailed Description

Holds the cache used by isBeforeInTranslationUnit.

The cache structure is complex enough to be worth breaking out of SourceManager.

getCachedResult()

bool clang::InBeforeInTUCacheEntry::getCachedResult ( unsigned  LOffset, unsigned  ROffset  ) const

inline

If the cache is valid, compute the result given the specified offsets in the LHS/RHS FileID's.

Definition at line 609 of file SourceManager.h.

isCacheValid()

bool clang::InBeforeInTUCacheEntry::isCacheValid ( ) const

inline

Return true if the currently cached values match up with the specified LHS/RHS query.

If not, we can't use the cache.

setCommonLoc()

void clang::InBeforeInTUCacheEntry::setCommonLoc ( FileID  commonFID, unsigned  lCommonOffset, unsigned  rCommonOffset, bool  LParentBeforeRParent  )

setQueryFIDs()

void clang::InBeforeInTUCacheEntry::setQueryFIDs ( FileID  LHS, FileID  RHS  )

inline

Set up a new query.

If it matches the old query, we can keep the cached answer.
