C++ (Cpp) iterator::dropAllReferences Beispiele

Beispiel #1

Datei: Module.cpp Projekt: Fininvest/llvm-mirror

// dropAllReferences() - This function causes all the subelements to "let go"
// of all references that they are maintaining.  This allows one to 'delete' a
// whole module at a time, even though there may be circular references... first
// all references are dropped, and all use counts go to zero.  Then everything
// is deleted for real.  Note that no operations are valid on an object that
// has "dropped all references", except operator delete.
