Class WingDocument

java.lang.Object
  org.dspace.app.xmlui.wing.element.AbstractWingElement
      org.dspace.app.xmlui.wing.element.WingDocument

All Implemented Interfaces:

WingElement, WingMergeableElement

public class WingDocument
extends AbstractWingElement
implements WingMergeableElement

A class representing a WingDocument. Documents contain three elements and they are all mandatory: meta, body, and options. Because they are all mandatory they are created at construction time. Note: We called the class "WingDocument" instead of just plain old "Document" so that it won't conflict with all the other documents out there like DOM's document.
