Detailed Description

Represents a list of guards.

The primary purpose of this class is to provide exception handling around guard invocations. An exception thrown by any guard will be caught, allowing the other guards to execute. Notification of guard exceptions is also available. The execute() method returns true if all guards return true. If an exception is thrown by any guard, the execute() method returns false.
