I'd suggest obtaining a copy of Design Patterns by Gamma et al - one of
the range of patterns it covers is the COMMAND pattern which:
"encapsulates a request as an object, thereby letting you parameterize
clients with different requests, queue or log requests, and support
undoable operations"
Aside from that, it's an excellent reference. Highly recommended.
