## Detailed Description

Interface for objects that can be waited on.

## Member Function Documentation

## ◆ GetMaxWaitObjectCount()

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.

## ◆ GetWaitObjects()

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.

## ◆ Wait()

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.
