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.

Examples

process.cc, and shell.cc.

Member Function Documentation

Callee()

template<typename T >

Local< Function > v8::FunctionCallbackInfo< T >::Callee

inline

Data()

template<typename T >

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

inline

The data argument specified when creating the callback.

GetIsolate()

template<typename T >

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

inline

The current Isolate.

Examples

process.cc, and shell.cc.

GetReturnValue()

template<typename T >

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

inline

The ReturnValue for the call.

Examples

shell.cc.

Holder()

template<typename T >

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

inline

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

inline

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

Length()

template<typename T >

int v8::FunctionCallbackInfo< T >::Length

inline

The number of available arguments.

Examples

process.cc, and shell.cc.

NewTarget()

template<typename T >

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

inline

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

operator[]()

template<typename T >

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

inline

Accessor for the available arguments.

Here is the call graph for this function:

This()

template<typename T >

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

inline

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