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.

GetIsolate()

template<typename T >

Isolate * v8::FunctionCallbackInfo< T >::GetIsolate

(

)

const

The current Isolate.

GetReturnValue()

template<typename T >

ReturnValue< T > v8::FunctionCallbackInfo< T >::GetReturnValue

(

)

const

The ReturnValue for the call.

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]).

IsConstructCall()

template<typename T >

bool v8::FunctionCallbackInfo< T >::IsConstructCall

(

)

const

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

Length()

template<typename T >

int v8::FunctionCallbackInfo< T >::Length

(

)

const

The number of available arguments.

NewTarget()

template<typename T >

Local< Value > v8::FunctionCallbackInfo< T >::NewTarget

(

)

const

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

operator[]()

template<typename T >

Local< Value > v8::FunctionCallbackInfo< T >::operator[]

(

int

i

)

const

Accessor for the available arguments.

This()

template<typename T >

Local< Object > v8::FunctionCallbackInfo< T >::This

(

)

const

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