Interface MdmObjectVisitor

All Known Subinterfaces:: Mdm10_1_0_3_ObjectVisitor, Mdm11_2_ObjectVisitor, Mdm11_ObjectVisitor

All Known Implementing Classes:: MdmBaseObjectVisitor

public interface MdmObjectVisitor

A visitor object that can execute operations on some of the 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.

MdmObjectVisitor has a visit method for most 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 MdmObjectVisitor. The acceptVisitor method passes the MdmObject and the context to the visit method. For example, you could call the acceptVisitor method on an MdmSchema and pass it your MdmObjectVisitor and context objects. The acceptVisitor method would then pass the MdmSchema and the context you passed it to the visitMdmSchema method of your MdmObjectVisitor.

A visit method of your MdmObjectVisitor 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 visitMdmSchema method might call the getSubSchemas method on the MdmSchema, 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.
