## info.bioinfweb.treegraph.document
Class Document

    java.lang.Object
      info.webinsel.util.ChangeMonitor
          info.webinsel.util.io.AbstractSaver
              info.webinsel.util.swing.SwingSaver
                  info.bioinfweb.treegraph.document.Document

All Implemented Interfaces:
  info.webinsel.util.ChangeMonitorable, info.webinsel.util.io.Savable, info.webinsel.util.swing.SwingSavable

    public class Document

extends info.webinsel.util.swing.SwingSaver
implements info.webinsel.util.ChangeMonitorable, info.webinsel.util.io.Savable, info.webinsel.util.swing.SwingSavable

Instances of this class contain the data for a tree and its formats as well as position-information for all `TreePositioner`s used with this `Document`.
Furthermore instances of this class contain lists of `TreePositioner`s and `TreeView`s which want to be alerted if the content of this `Document` is modified. `Document` acts as the model in MVC- paradigm used in the user-interface of TreeGraph 2.
