Type Alias

JSObjectInitializeCallback

The callback invoked when an object is first created.

Declaration

typealias JSObjectInitializeCallback = (JSContextRef?, JSObjectRef?) -> Void

Parameters

ctx

The execution context to use.

object

The JSObject being created.

Discussion

If you named your function Initialize, you would declare it like this:

void Initialize(JSContextRef ctx, JSObjectRef object);

Unlike the other object callbacks, the initialize callback is called on the least derived class (the parent class) first, and the most derived class last.
