Detailed Description

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

Definition at line 3995 of file v8.h.

Member Function Documentation

◆ GetBoundFunction()

Local< v8::Value > v8::Function::GetBoundFunction ( ) const

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

Definition at line 5158 of file api.cc.

◆ GetDebugName()

Local< Value > v8::Function::GetDebugName ( ) const

displayName if it is set, otherwise name if it is configured, otherwise function name, otherwise inferred name.

Definition at line 5063 of file api.cc.

◆ GetDisplayName()

Local< Value > v8::Function::GetDisplayName ( ) const

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

Definition at line 5075 of file api.cc.

◆ GetInferredName()

Local< Value > v8::Function::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.

Definition at line 5051 of file api.cc.

◆ GetScriptColumnNumber()

int v8::Function::GetScriptColumnNumber ( ) const

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

Definition at line 5128 of file api.cc.

◆ GetScriptLineNumber()

int v8::Function::GetScriptLineNumber ( ) const

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

Definition at line 5113 of file api.cc.

◆ New()

Local< Function > v8::Function::New ( Local< Context >  context,
FunctionCallback  callback,
Local< Value >  data = Local<Value>(),
int  length = 0,
ConstructorBehavior  behavior = ConstructorBehavior::kAllow,
SideEffectType  side_effect_type = SideEffectType::kHasSideEffect 
)
static

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

Definition at line 4919 of file api.cc.

◆ NewInstanceWithSideEffectType()

MaybeLocal< Object > v8::Function::NewInstanceWithSideEffectType ( Local< Context >  context,
int  argc,
Local< Value >  argv[],
SideEffectType  side_effect_type = SideEffectType::kHasSideEffect 
) const

When side effect checks are enabled, passing kHasNoSideEffect allows the constructor to be invoked without throwing. Calls made within the constructor are still checked.

Definition at line 4947 of file api.cc.

◆ ScriptId()

int v8::Function::ScriptId ( ) const

Returns scriptId.

Definition at line 5143 of file api.cc.
