org.jdaemon.era.xml
Class AbstractXMLCube  

java.lang.Object
  java.util.AbstractCollection
      org.jdaemon.era.AbstractCube
          org.jdaemon.era.xml.AbstractXMLCube

All Implemented Interfaces:

java.util.Collection, org.jdaemon.era.Cube, java.lang.Iterable, XMLCube

Direct Known Subclasses:

FilteredXMLCube

---

public abstract class AbstractXMLCube

extends org.jdaemon.era.AbstractCube

implements XMLCube

Abstract implementation of XMLCube. Extends AbstractCube (for completeness -- even though it does not reuse much -- may have to revise this class or AbstractCube). Note that AbstractCube more closely matches the requirements of the JavaCube than the XMLCube.
