Method Detail

acceptsSource

public boolean acceptsSource(java.lang.Object edge,
                             java.lang.Object port)

Specified by:

acceptsSource in interface org.jgraph.graph.GraphModel

Overrides:

acceptsSource in class org.jgraph.graph.DefaultGraphModel

acceptsTarget

public boolean acceptsTarget(java.lang.Object edge,
                             java.lang.Object port)

Specified by:

acceptsTarget in interface org.jgraph.graph.GraphModel

Overrides:

acceptsTarget in class org.jgraph.graph.DefaultGraphModel

insert

public void insert(java.lang.Object[] roots,
                   java.util.Map attributes,
                   org.jgraph.graph.ConnectionSet cs,
                   org.jgraph.graph.ParentMap pm,
                   javax.swing.undo.UndoableEdit[] edits)

Extends DefaultGraphModel insert method to check for large changes and sets the undoDisabled flag to true. Disabling the undo provides large performance and memory footprint advantages on huge inserts.

Specified by:

insert in interface org.jgraph.graph.GraphModel

Overrides:

insert in class org.jgraph.graph.DefaultGraphModel

edit

public void edit(java.util.Map attributes,
                 org.jgraph.graph.ConnectionSet cs,
                 org.jgraph.graph.ParentMap pm,
                 javax.swing.undo.UndoableEdit[] edits)

Specified by:

edit in interface org.jgraph.graph.GraphModel

Overrides:

edit in class org.jgraph.graph.DefaultGraphModel
