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 > Data

(

)

const

The data argument specified when creating the callback.

Definition at line 639 of file v8-function-callback.h.

References v8::api_internal::GetFunctionTemplateData(), and GetIsolate().

GetIsolate()

template<typename T>

Isolate * GetIsolate

(

)

const

The current Isolate.

GetReturnValue()

template<typename T>

ReturnValue< T > GetReturnValue

(

)

const

The ReturnValue for the call.

Definition at line 650 of file v8-function-callback.h.

IsConstructCall()

template<typename T>

bool IsConstructCall

(

)

const

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

Definition at line 655 of file v8-function-callback.h.

References NewTarget().

Length()

template<typename T>

int Length

(

)

const

The number of available arguments.

Referenced by operator[]().

NewTarget()

template<typename T>

Local< Value > NewTarget

(

)

const

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

int

i

)

const

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