public class DefaultLogixManager
extends AbstractManager
implements LogixManager, PropertyChangeListener

Basic Implementation of a LogixManager.

Note that Logix system names must begin with IX, and be followed by a string, usually, but not always, a number. All alphabetic characters in a Logix system name must be upper case. This is enforced when a Logix is created.

The system names of Conditionals belonging to a Logix begin with the Logix's system name, then there is a capital C and a number.
