Here is the call graph for this function:

GetIsolate()

template<typename T >

Isolate * v8::WeakCallbackInfo< T >::GetIsolate ( ) const

inline

GetParameter()

template<typename T >

T * v8::WeakCallbackInfo< T >::GetParameter ( ) const

inline

SetSecondPassCallback()

template<typename T >

void v8::WeakCallbackInfo< T >::SetSecondPassCallback ( Callback  callback ) const

inline

When a weak callback is first invoked the embedders must Reset() the handle which triggered the callback. The handle itself is unusable for anything else. No other V8 API calls may be called in the first callback. Additional work requires scheduling a second invocation via SetSecondPassCallback() which will be called some time after all the initial callbacks are processed.

The second pass callback is prohibited from executing JavaScript. Embedders should schedule another callback in case this is required.
