Member Function Documentation

allUsesReplacedWith()

template<typename KeyT, typename ValueT, typename Config>

void llvm::ValueMapCallbackVH< KeyT, ValueT, Config >::allUsesReplacedWith ( Value * )

inlineoverridevirtual

Callback for Value RAUW.

Called when this->getValPtr()->replaceAllUsesWith(new_value) is called, before any of the uses have actually been replaced. If WeakTrackingVH were implemented as a CallbackVH, it would use this method to call setValPtr(new_value). AssertingVH would do nothing in this method.

Reimplemented from llvm::CallbackVH.

Definition at line 275 of file ValueMap.h.

deleted()

template<typename KeyT, typename ValueT, typename Config>

void llvm::ValueMapCallbackVH< KeyT, ValueT, Config >::deleted ( )

inlineoverridevirtual

Callback for Value destruction.

Called when this->getValPtr() is destroyed, inside ~Value(), so you may call any non-virtual Value method on getValPtr(), but no subclass methods. If WeakTrackingVH were implemented as a CallbackVH, it would use this method to call setValPtr(NULL). AssertingVH would use this method to cause an assertion failure.

All implementations must remove the reference from this object to the Value that's being destroyed.

Reimplemented from llvm::CallbackVH.
