java.lang.Object | +--oracle.olapi.metadata.mdm.MdmBaseObjectVisitor
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.
