public abstract class MdmBaseObjectVisitor

extends java.lang.Object

implements MdmObjectVisitor

An implementation of the MdmObjectVisitor interface that adds methods for visiting more classes in the MdmObject class hierarchy. With your visitor, you can implement polymorphic behavior without having access to the internal code of MdmObject or its subclasses.

MdmBaseObjectVisitor has a visit method for each of the classes in the MdmObject class hierarchy. MdmObject and its subclasses have an acceptVisitor method. The acceptVisitor method takes as its input parameters an MdmObjectVisitor and a context object. When you call the acceptVisitor method on an MdmObject, the acceptVisitor method calls the corresponding visit method on your MdmBaseObjectVisitor. The acceptVisitor method passes the MdmObject and the context to the visit method. For example, you could call the acceptVisitor method on an MdmMeasure and pass it your MdmBaseObjectVisitor and context objects. The acceptVisitor method would then pass the MdmMeasure and the context you passed it to the visitMdmMeasure method of your MdmObjectVisitor.

A visit method of your MdmBaseObjectVisitor can perform whatever operations you want on the MdmObject it receives, and your context object can be anything you want it to be. For example, a visitMdmMeasure method might call the getDimensions method on the MdmMeasure, and then call methods on the context object to format and display the resulting information. A visit method must return a Java Object, which can be whatever you want it to be.
