Detailed Description

Wrapper around OptionalDirectoryEntryRef that degrades to 'const DirectoryEntry*', facilitating incremental patches to propagate DirectoryEntryRef.

This class can be used as return value or field where it's convenient for an OptionalDirectoryEntryRef to degrade to a 'const DirectoryEntry*'. The purpose is to avoid code churn due to dances like the following:

// Old code.
lvalue = rvalue;
 
// Temporary code from an incremental patch.
OptionalDirectoryEntryRef MaybeF = rvalue;
lvalue = MaybeF ? &MaybeF.getDirectoryEntry() : nullptr;
 
// Final code.
lvalue = rvalue;

FIXME: Once DirectoryEntryRef is "everywhere" and DirectoryEntry::LastRef and DirectoryEntry::getName have been deleted, delete this class and replace instances with OptionalDirectoryEntryRef.
