Active object (Symbian OS)

An active object framework is a callback-based form of multitasking for computer systems. Specifically, it is a form of cooperative multitasking and is an important feature of the Symbian operating system. When the asynchronous task completes, the operating system identifies the thread containing the requesting active object, and wakes it up. An "active scheduler" in the thread identifies the object that made the request, and passes control back to that object.
