Member Function Documentation

◆ Call() [1/2]

MaybeLocal< Value > v8::Function::Call	(	Local< Context >	context,
		Local< Value >	recv,
		int	argc,
		Local< Value >	argv[]
	)

◆ Call() [2/2]

MaybeLocal< Value > v8::Function::Call	(	v8::Isolate *	isolate,
		Local< Context >	context,
		Local< Value >	recv,
		int	argc,
		Local< Value >	argv[]
	)

◆ Cast()

static Function * v8::Function::Cast ( Value * value )

inlinestatic

◆ Experimental_IsNopFunction()

bool v8::Function::Experimental_IsNopFunction ( ) const

Returns true if the function does nothing. The function returns false on error. Note that this function is experimental. Embedders should not rely on this existing. We may remove this function in the future.

◆ FunctionProtoToString()

MaybeLocal< String > v8::Function::FunctionProtoToString ( Local< Context > context )

Calls builtin Function.prototype.toString on this function. This is different from Value::ToString() that may call a user-defined toString() function, and different than Object::ObjectProtoToString() which always serializes "[object Function]".

◆ GetBoundFunction()

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

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

◆ GetDebugName()

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

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

◆ 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.

◆ GetName()

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

◆ GetScriptColumnNumber()

int v8::Function::GetScriptColumnNumber ( ) const

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

◆ GetScriptLineNumber()

int v8::Function::GetScriptLineNumber ( ) const

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

◆ GetScriptOrigin()

ScriptOrigin v8::Function::GetScriptOrigin ( ) const

◆ GetScriptStartPosition()

int v8::Function::GetScriptStartPosition ( ) const

Returns zero based start position (character offset) of function body and kLineOffsetNotFound if no information available.

◆ New()

static MaybeLocal< 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.

◆ NewInstance() [1/2]

MaybeLocal< Object > v8::Function::NewInstance ( Local< Context > context ) const

inline

◆ NewInstance() [2/2]

MaybeLocal< Object > v8::Function::NewInstance	(	Local< Context >	context,
		int	argc,
		Local< Value >	argv[]
	)		const

◆ 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.

◆ ScriptId()

int v8::Function::ScriptId ( ) const

Returns scriptId.

◆ SetName()

void v8::Function::SetName ( Local< String > name )

Member Data Documentation

◆ kLineOffsetNotFound

const int v8::Function::kLineOffsetNotFound
