Enclosing class:

GraphModelEvent

public static interface GraphModelEvent.GraphViewChange

Defines the interface for objects that may be used to represent a change to the view.

Method Summary

Map	getAttributes() Returns a map that contains (object, map) pairs which holds the new attributes for each changed cell.
Object[]	getChanged() Returns the objects that have changed.
Object[]	getContext() Returns the objects that have not changed explicitly, but implicitly because one of their dependent cells has changed.
Object	getSource() Returns the source of this change.

Method Detail

getSource

Object getSource()

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

getChanged

Object[] getChanged()

Returns the objects that have changed.

getAttributes

Map getAttributes()

Returns a map that contains (object, map) pairs which holds the new attributes for each changed cell. Note: This returns a map of (cell, map) pairs for an insert on a model that is not an attribute store. Use getStoredAttributeMap to access the attributes that have been stored in the model.

getContext

Object[] getContext()

Returns the objects that have not changed explicitly, but implicitly because one of their dependent cells has changed. This is typically used to return the edges that are attached to vertices, which in turn have been resized or moved.
