|class CDelayedOp : public CActive|
The base class for the delayed operations. All of the delayed operations must derive from it.

|IMPORT_C void||DoCancel||(||)||[private, virtual]|
Implements cancellation of an outstanding request.
This function is called as part of the active object's Cancel() .
It must call the appropriate cancel function offered by the active object's asynchronous service provider. The asynchronous service provider's cancel is expected to act immediately.
Derived classes must implement their asynchronous processing in this method. The GetPlugin method can only be used from within this method. Returns boolean: ETrue if op is yielding and needs to be called again, or EFalse if op is done.
|IMPORT_C CBasePlugin &||GetPlugin||(||)||[protected]|
Returns the plugin instance associated with this operation. Available only from within the ExecuteOpL method.
|IMPORT_C void||RunL||(||)||[private, virtual]|
Handles an active object's request completion event.
A derived class must provide an implementation to handle the completed request. If appropriate, it may issue another request.
The function is called by the active scheduler when a request completion event occurs, i.e. after the active scheduler's WaitForAnyRequest() function completes.
Before calling this active object's RunL() function, the active scheduler has:
1. decided that this is the highest priority active object with a completed request
2. marked this active object's request as complete (i.e. the request is no longer outstanding)
