+/*
+    This header file defines an object to help queue and serialize
+    asynchronous operations.
+
+    Background:
+
+    To perform an operation asynchronously in Media Foundation, an object
+    does one of the following:
+
+        1. Calls MFPutWorkItem(Ex), using either a standard work queue
+           identifier or a caller-allocated work queue. The work-queue
+           thread invokes the object's callback.
+
+        2. Creates an async result object (IMFAsyncResult) and calls
+           MFInvokeCallback to invoke the object's callback.
+
+    Ultimately, either of these cause the object's callback to be invoked
+    from a work-queue thread. The object can then complete the operation
+    inside the callback.
+
+    However, the Media Foundation platform may dispatch async callbacks in
+    parallel on several threads. Putting an item on a work queue does NOT
+    guarantee that one operation will complete before the next one starts,
+    or even that work items will be dispatched in the same order they were
+    called.
+
+    To serialize async operations that should not overlap, an object should
+    use a queue. While one operation is pending, subsequent operations are
+    put on the queue, and only dispatched after the previous operation is
+    complete.
+
+    The granularity of a single "operation" depends on the requirements of
+    that particular object. A single operation might involve several
+    asynchronous calls before the object dispatches the next operation on
+    the queue.
+

+// OpQueue class template
+//
+// Base class for an async operation queue.
+//
+// TOperation: The class used to describe operations. This class must
+//          implement IUnknown.
+//
+// The OpQueue class is an abstract class. The derived class must
+// implement the following pure-virtual methods:
+//
+// - IUnknown methods (AddRef, Release, QI)
+//
+// - DispatchOperation:
+//
+//      Performs the asynchronous operation specified by pOp.
+//
+//      At the end of each operation, the derived class must call
+//      ProcessQueue to process the next operation in the queue.
+//
+//      NOTE: An operation is not required to complete inside the
+//      DispatchOperation method. A single operation might consist
+//      of several asynchronous method calls.
+//
+// - ValidateOperation:
+//
+//      Checks whether the object can perform the operation specified
+//      by pOp at this time.
+//
+//      If the object cannot perform the operation now (e.g., because
+//      another operation is still in progress) the method should
+//      return MF_E_NOTACCEPTING.
