Detailed Description

Counted objects are objects that use a counter to keep track of how many other objects need them, and delete themselves when nobody needs them anymore. A counted object has an AddRef method that increments its counter, and a Release method that decrements it. When the value of the counter reaches zero, the object is deleted.

Take a look at TMCCountedCreateHelper to see how to create and return a counted object

Member Function Documentation

uint32 TMCSMPCountedObject::AddRef (   )  [inline, virtual]

Increments the reference count of the object Implements IMCUnknown. Reimplemented in TCountedTimeBased, TCountedRenderable, TCountedRenderingCallbacks, and TBasicSmpThread.

void TMCSMPCountedObject::Create (  TMCSMPCountedObject **  outObject  )  [static]

virtual MCErr MCCOMAPI TMCSMPCountedObject::QueryInterface (  const MCIID &  riid, void **  ppvObj )  [virtual]

Check if the object supports a given interface and returns a pointer to that interface if it does. Note that QueryInterface will increment the reference count of the object by one if the interface is found. Parameters: riid  GUID of the interface ppvObj  A pointer to the pointer being returned. Implements IMCUnknown. Reimplemented in TCountedTimeBased, TCountedRenderable, TCountedRenderingCallbacks, and TBasicSmpThread.

uint32 TMCSMPCountedObject::Release (   )  [inline, virtual]

Decrements the reference count of the object. If the reference count reaches zero, the object is destroyed. Implements IMCUnknown. Reimplemented in TCountedTimeBased, TCountedRenderable, TCountedRenderingCallbacks, and TBasicSmpThread.
