/**
|
|
* Contains logic for storing and checking rules on entities
|
|
*
|
|
* RulesCheckers are used by Table classes to ensure that the
|
|
* current entity state satisfies the application logic and business rules.
|
|
*
|
|
* RulesCheckers afford different rules to be applied in the create and update
|
|
* scenario.
|
|
*
|
|
* ### Adding rules
|
|
*
|
|
* Rules must be callable objects that return true/false depending on whether
|
|
* the rule has been satisfied. You can use RulesChecker::add(), RulesChecker::addCreate(),
|
|
* RulesChecker::addUpdate() and RulesChecker::addDelete to add rules to a checker.
|
|
*
|
|
* ### Running checks
|
|
*
|
|
* Generally a Table object will invoke the rules objects, but you can manually
|
|
* invoke the checks by calling RulesChecker::checkCreate(), RulesChecker::checkUpdate() or
|
|
* RulesChecker::checkDelete().
