#define IMPLEMENT_IOBJECT | ( | component | ) |
Helper macro to implement the IObject methods automatically.
Put this at the beginning of your class, specifiying the class name as the parameter, and it will automatically implement all the IObject methods. You also need to define an interface map.
Interface * get | ( | IObject * | aObj | ) |
XPLC equivalent to dynamic_cast.
This templated function is a typesafe way to call the getInterface method of a component and cast it properly. If the component does not support the interface, a NULL pointer will be returned.

References IObject::getInterface().
Interface * mutate | ( | IObject * | aObj | ) |
A version of get() that releases its parameter.
This templated function is very similar to the "get" one, except that it automatically releases the inbound reference, without regard whether the getInterface actually yielded something.
