Detailed Description

A JavaScript function object (ECMA-262, 15.3).

Definition at line 2544 of file v8.h.

Member Function Documentation

◆ Call()

Local<Value> Call ( Handle< Value recv,
int  argc,
Handle< Value argv[] 

◆ Cast()

Function * Cast ( v8::Value value)

Definition at line 6549 of file v8.h.

◆ GetBoundFunction()

Local<Value> GetBoundFunction ( ) const

Returns the original function if this function is bound, else returns v8::Undefined.

◆ GetDisplayName()

Handle<Value> GetDisplayName ( ) const

User-defined name assigned to the "displayName" property of this function. Used to facilitate debugging and profiling of JavaScript code.

◆ GetInferredName()

Handle<Value> GetInferredName ( ) const

Name inferred from variable or property assignment of this function. Used to facilitate debugging and profiling of JavaScript code written in an OO style, where many functions are anonymous but are assigned to object properties.

◆ GetName()

Handle<Value> GetName ( ) const

◆ GetScriptColumnNumber()

int GetScriptColumnNumber ( ) const

Returns zero based column number of function body and kLineOffsetNotFound if no information available.

◆ GetScriptLineNumber()

int GetScriptLineNumber ( ) const

Returns zero based line number of function body and kLineOffsetNotFound if no information available.

◆ GetScriptOrigin()

ScriptOrigin GetScriptOrigin ( ) const

◆ IsBuiltin()

bool IsBuiltin ( ) const

Tells whether this function is builtin.

◆ New()

static Local<Function> New ( Isolate isolate,
FunctionCallback  callback,
Local< Value data = LocalValue >(),
int  length = 0 

Create a function in the current execution context for a given FunctionCallback.

◆ NewInstance() [1/2]

Local<Object> NewInstance ( ) const

◆ NewInstance() [2/2]

Local<Object> NewInstance ( int  argc,
Handle< Value argv[] 
) const

◆ ScriptId()

int ScriptId ( ) const

Returns scriptId.

◆ SetName()

void SetName ( Handle< String name)
