Constructor & Destructor Documentation

JSFunction() [1/3]

JSFunction

(

)

Create an empty Function.

NOTE: It is OKAY to create this without calling SetJSContext() first.

JSFunction() [2/3]

JSFunction

(

const JSFunction &

other

)

Copy constructor (shallow copy, will point to same instance)

~JSFunction()

JSFunction() [3/3]

JSFunction ( JSContextRef ctx, JSValueRef val )

protected

Member Function Documentation

context()

JSContextRef context ( ) const

inline

Get the bound context for this JSFunction (it is cached at creation).

IsValid()

bool IsValid

(

)

const

Whether or not this is a valid, callable Function object.

operator JSObjectRef()

operator JSObjectRef ( ) const

inline

Get the underlying JSObjectRef (JavaScriptCore C API)

operator()() [1/2]

JSValue operator()

(

const JSArgs &

args

)

Call function (using Global Object for 'this') and return the result.

operator()() [2/2]

JSValue operator()	(	const JSObject &	thisObject,
		const JSArgs &	args )

Call function (with explicit object for 'this') and return the result.

operator=()

JSFunction & operator=

(

const JSFunction &

other

)

Assignment (shallow assignment, will point to same instance)

set_context()

void set_context ( JSContextRef context )

inline

Set the JSContext for this JSFunction.

Note

JSFunctions created from within a JSCallback have a temporary JSContext that is destroyed when the callback returns. You will need to "move" any JSFunctions created within these callbacks to the View's main context (call set_context() with the main context) before using them outside the callback.
