◆ getName()

StringRef clang::FileEntryRef::getName ( ) const

inline

The name of this FileEntry.

If a VFS uses 'use-external-name', this is the redirected name. See getRequestedName().

◆ getNameAsRequested()

StringRef clang::FileEntryRef::getNameAsRequested ( ) const

inline

The name of this FileEntry, as originally requested without applying any remappings for VFS 'use-external-name'.

FIXME: this should be the semantics of getName(). See comment in FileManager::getFileRef().

bool clang::FileEntryRef::isSameRef ( const FileEntryRef & RHS ) const

inline

Check if RHS referenced the file in exactly the same way.

Definition at line 132 of file FileEntry.h.

Referenced by llvm::DenseMapInfo< clang::FileEntryRef >::isEqual().

◆ operator const FileEntry *()

clang::FileEntryRef::operator const FileEntry * ( ) const

inline

Allow FileEntryRef to degrade into 'const FileEntry*' to facilitate incremental adoption.

The goal is to avoid code churn due to dances like the following:

// Old code.
lvalue = rvalue;
 
// Temporary code from an incremental patch.
lvalue = &rvalue.getFileEntry();
 
// Final code.
lvalue = rvalue;

FIXME: Once FileEntryRef is "everywhere" and FileEntry::LastRef and FileEntry::getName have been deleted, delete this implicit conversion.
