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

◆ 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]).

◆ HolderSoonToBeDeprecated()

template<typename T >
Local< Object > v8::FunctionCallbackInfo< T >::HolderSoonToBeDeprecated
inline

◆ 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. Returns undefined if the index is out of bounds.

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.
