* InstallObject
|
|
* abstract class for things that get installed
|
|
* encapsulates a single action
|
|
* The way your subclass is used:
|
|
* Constructor should collect all the data needed to perform the action
|
|
* Prepare() does any lengthy set-up action (uncompressing, patching, etc.)
|
|
* Complete() is called to complete the action
|
|
* Abort() is called when update is aborted
|
|
* You are guaranteed to be called with Complete() or Abort() before finalize
|
|
* If your Complete() throws, you'll also get called with an Abort()
