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.

Definition at line 93 of file v8-function-callback.h.

Member Function Documentation

Data()

template<typename T >

Local< Value > Data

The data argument specified when creating the callback.

Definition at line 440 of file v8-function-callback.h.

GetIsolate()

template<typename T >

Isolate * GetIsolate

The current Isolate.

Definition at line 445 of file v8-function-callback.h.

GetReturnValue()

template<typename T >

ReturnValue< T > GetReturnValue

The ReturnValue for the call.

Definition at line 450 of file v8-function-callback.h.

Holder()

template<typename T >

Local< Object > Holder

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 430 of file v8-function-callback.h.

IsConstructCall()

template<typename T >

bool IsConstructCall

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

Definition at line 455 of file v8-function-callback.h.

Length()

template<typename T >

int Length

The number of available arguments.

Definition at line 460 of file v8-function-callback.h.

NewTarget()

template<typename T >

Local< Value > NewTarget

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

Definition at line 435 of file v8-function-callback.h.

operator[]()

template<typename T >

Local< Value > operator[]

(

int

i

)

const

Accessor for the available arguments. Returns undefined if the index is out of bounds.

Definition at line 417 of file v8-function-callback.h.

References v8::Undefined().

This()

template<typename T >

Local< Object > This

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

Definition at line 424 of file v8-function-callback.h.
