Description

Pre-defined command execution skeletons.

Any command can be configured to use a specific handling pattern on invocation. Moreover, there is a default handling pattern for commands. These patterns define the steps necessary for getting the command actually invoked (template method pattern). A pattern may cause the command to be enqueued, registered for UNDO or dispatched into a background thread. To carry out the work, HandlingPattern implementations are allowed to invoke the CommandImpl API directly.

Todo:

it is not clear what's the difference between "throw" and "no-throw" pattern

any integration with the (yet undefined as of 9/09) SteamDispatcher is missing.
