Detailed Description

template<typename T>
class v8::FunctionCallbackInfo< T >

The argument information given to function call callbacks. This class provides access to information about the context of the call, including the receiver, the number and values of arguments, and the holder of the function.

Member Function Documentation

◆ Data()

template<typename T >
Local< Value > v8::FunctionCallbackInfo< T >::Data ( ) const

The data argument specified when creating the callback.

Definition at line 9727 of file v8.h.

◆ GetIsolate()

template<typename T >
Isolate * v8::FunctionCallbackInfo< T >::GetIsolate ( ) const

The current Isolate.

Definition at line 9733 of file v8.h.

◆ GetReturnValue()

template<typename T >
ReturnValue< T > v8::FunctionCallbackInfo< T >::GetReturnValue ( ) const

The ReturnValue for the call.

Definition at line 9739 of file v8.h.

◆ Holder()

template<typename T >
Local< Object > v8::FunctionCallbackInfo< T >::Holder ( ) const

If the callback was created without a Signature, this is the same value as This(). If there is a signature, and the signature didn't match This() but one of its hidden prototypes, this will be the respective hidden prototype.

Note that this is not the prototype of This() on which the accessor referencing this callback was found (which in V8 internally is often referred to as holder [sic]).

Definition at line 9715 of file v8.h.

◆ IsConstructCall()

template<typename T >
bool v8::FunctionCallbackInfo< T >::IsConstructCall ( ) const

Indicates whether this is a regular call or a construct call.

Definition at line 9745 of file v8.h.

◆ Length()

template<typename T >
int v8::FunctionCallbackInfo< T >::Length ( ) const

The number of available arguments.

Definition at line 9751 of file v8.h.

◆ NewTarget()

template<typename T >
Local< Value > v8::FunctionCallbackInfo< T >::NewTarget ( ) const

For construct calls, this returns the "new.target" value.

Definition at line 9721 of file v8.h.

◆ operator[]()

template<typename T >
Local< Value > v8::FunctionCallbackInfo< T >::operator[] ( int  i) const

Accessor for the available arguments.

Definition at line 9702 of file v8.h.

◆ This()

template<typename T >
Local< Object > v8::FunctionCallbackInfo< T >::This ( ) const

Returns the receiver. This corresponds to the "this" value.

Definition at line 9709 of file v8.h.
