java.lang.Object

com.ergotech.secs.SecsTrigger

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

SecsMsg

public class SecsTrigger
extends java.lang.Object
implements java.io.Serializable

This object is the super class for all the SecsMessages. It is used by GEM as the basis for non-message based state changes. For example, GEM permits that some state changes can occur from the equipment, the user pushing a button for instance. In this case, the developer can use a SecsTrigger subclass to send the state change through the state diagram and effect this state change.

processSelf

public boolean processSelf(java.lang.Object messageHandler)
                    throws SecsException

Calls the message handle object. The message handle object may implement the method "processMessage" with one argument a SecsTrigger object. If this method is implemented then the incoming trigger will be passed to the "processMessage" method.

The SecsMsg subclass of this object provides for more functionality in handling incoming messages. If this method returns false, the gem diagram will ignore any possible changes to the state that would have accured by this message.

Throws:

SecsException
