|
|
* per-recipe behavior, and may implement _finalize for actions to be
|
|
* taken once after recipes are run.
|
|
*
|
|
* For actions that need to be taken once before recipes are run
|
|
* _preExecution may be overriden but the overridden method must
|
|
* call the parent method to ensure the appropriate checks occur.
|
|
*
|
|
* Other methods should be overridden with care, to maintain the life
|
|
* cycle events and error reporting implemented by this class.
