Member Function Documentation

◆ Call()

V8_WARN_UNUSED_RESULT MaybeLocal<Value> Call	(	Local< Context >	context,
		Local< Value >	recv,
		int	argc,
		Local< Value >	argv[]
	)

◆ Cast()

Function * Cast ( v8::Value * value )

static

Definition at line 12276 of file v8.h.

◆ FunctionProtoToString()

V8_WARN_UNUSED_RESULT MaybeLocal<String> 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> GetBoundFunction ( ) const

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

◆ GetDebugName()

Local<Value> GetDebugName ( ) const

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

◆ GetInferredName()

Local<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()

Local<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

◆ New()

static MaybeLocal<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]

V8_WARN_UNUSED_RESULT MaybeLocal<Object> NewInstance ( Local< Context > context ) const

inline

Definition at line 4719 of file v8.h.

References Function::NewInstance().

◆ NewInstance() [2/2]

V8_WARN_UNUSED_RESULT MaybeLocal<Object> NewInstance	(	Local< Context >	context,
		int	argc,
		Local< Value >	argv[]
	)		const

Referenced by Function::NewInstance().

◆ NewInstanceWithSideEffectType()

V8_WARN_UNUSED_RESULT MaybeLocal<Object> 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 ScriptId ( ) const

Returns scriptId.

◆ SetName()

void SetName ( Local< String > name )

◆ V8_DEPRECATED()

V8_DEPRECATED	(	"Use v8::Object::Get() instead to look up \"displayName\". " "V8 and DevTools no longer use \"displayName\" in stack " "	traces,
		but the standard \"name\" property. " "See http://crbug.com/1177685."
	)		const

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