inserted - a set of roots that were inserted

Method Detail

handleEmptyGroups

protected void handleEmptyGroups(java.lang.Object[] groups)

Adds the groups that become empty to the cells that will be removed. (Auto remove empty cells.) Removed cells will be re-inserted on undo, and the parent- child relations will be restored.

isSignificant

public boolean isSignificant()

Specified by:

isSignificant in interface javax.swing.undo.UndoableEdit

getSource

public java.lang.Object getSource()

Returns the source of this change. This can either be a view or a model, if this change is a GraphModelChange.

Specified by:

getSource in interface GraphModelEvent.GraphViewChange

getChanged

public java.lang.Object[] getChanged()

Returns the cells that have changed. This includes the cells that have been changed through a call to getAttributes and the edges that have been changed with the ConnectionSet.

Specified by:

getChanged in interface GraphModelEvent.GraphViewChange

getContext

public java.lang.Object[] getContext()

Returns the objects that have not changed explicitly, but implicitly because one of their dependent cells has changed.

Specified by:

getContext in interface GraphModelEvent.GraphViewChange

getInserted

public java.lang.Object[] getInserted()

Returns the cells that were inserted.

Specified by:

getInserted in interface GraphModelEvent.GraphModelChange

getRemoved

Returns the cells that were inserted.

Specified by:

getRemoved in interface GraphModelEvent.GraphModelChange

getStoredAttributeMap

public java.util.Map getStoredAttributeMap()

Returns a map that contains (object, map) pairs of the attributes that have been stored in the model.

Specified by:

getStoredAttributeMap in interface GraphModelEvent.GraphModelChange

getAttributeMap

public java.util.Map getAttributeMap()

Returns a map of (object, view attributes). The objects are model objects which need to be mapped to views.

Specified by:

getAttributeMap in interface GraphModelEvent.GraphViewChange

redo

public void redo()
          throws javax.swing.undo.CannotRedoException

Redoes a change.

Specified by:
