Member Function Documentation

virtual unsigned int Waitable::GetMaxWaitObjectCount ( ) const

pure virtual

Maximum number of wait objects that this object can return.

Returns

the maximum number of wait objects

Implemented in BufferedTransformation, and Redirector.

virtual void Waitable::GetWaitObjects ( WaitObjectContainer &  container, CallStack const &  callStack  )

pure virtual

Retrieves waitable objects.

Parameters

container	the wait container to receive the references to the objects.
callStack	CallStack object used to select waitable objects

GetWaitObjects is usually called in one of two ways. First, it can be called like something.GetWaitObjects(c, CallStack("my func after X", 0));. Second, if in an outer GetWaitObjects() method that itself takes a callStack parameter, it can be called like innerThing.GetWaitObjects(c, CallStack("MyClass::GetWaitObjects at X", &callStack));.

Implemented in BufferedTransformation, and Redirector.

bool Waitable::Wait	(	unsigned long	milliseconds,
		CallStack const &	callStack
	)

Wait on this object.

Returns

true if the wait succeeded, false otherwise

Wait() is the same as creating an empty container, calling GetWaitObjects(), and then calling Wait() on the container.
