Here is the call graph for this function:

GetIsolate()

template<typename T >

V8_INLINE Isolate * v8::WeakCallbackInfo< T >::GetIsolate ( ) const

inline

Definition at line 38 of file v8-weak-callback-info.h.

GetParameter()

template<typename T >

V8_INLINE T * v8::WeakCallbackInfo< T >::GetParameter ( ) const

inline

Definition at line 39 of file v8-weak-callback-info.h.

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.
