Interface GraphNodeHooks

All Known Implementing Classes:

NetNode

public abstract interface GraphNodeHooks

extends Serializable

A set of methods that nodes in a GraphModel may implement. If the objects you use to represent nodes implement this interface, they will get the appropriate calls. NetNode implements these.

Method Detail

postConnect

public void postConnect(GraphModel gm,
                        Object anotherNode,
                        Object myPort,
                        Object otherPort)

Do some application specific action just after this node is connected to another node. the arguments contain some info about what ports were connected.

postDisconnect

public void postDisconnect(GraphModel gm,
                           Object anotherNode,
                           Object myPort,
                           Object otherPort)

Do some application specific action just after this node is disconnected from another node. the arguments contain some info about what ports were connected.

canConnectTo

public boolean canConnectTo(GraphModel gm,
                            Object otherNode,
                            Object otherPort,
                            Object myPort)

Allow foir application specific rules about which nodes can be connected to which other nodes. This is called from the NetPort, so the port has first say as to whether it can be connected to some other port. NetPort.canConnectTo() just calls NetNode.canConnectTo(). By default anything can be connected to anything.

postPlacement

public void postPlacement(Editor ed)

Do some application specific actions after the node is placed in a drawing area.

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener l)

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener l)

initialize

public void initialize(Hashtable props)

setHighlight

public void setHighlight(boolean b)

dispose

public void dispose()
