Class AbstractBuilderNode

java.lang.Object
  com.virtuosotechnologies.lib.basiccommand.builder.AbstractBuilderNode

All Implemented Interfaces:

EventListener, PropertySetListener

Direct Known Subclasses:

AbstractBranchBuilderNode, AbstractElementBuilderNode

public abstract class AbstractBuilderNode

extends Object

implements PropertySetListener

A skeletal implementation for builder nodes. Note that this builder registers itself as a PropertySetListener on the CommandNode, so subclasses do not need to do so again.

AbstractBuilderNode

protected AbstractBuilderNode(CommandNode commandNode,
                              AbstractBranchBuilderNode parent,
                              int index)

Constructor

Method Detail

getParent

protected final AbstractBranchBuilderNode getParent()

Return the parent

getCommandNode

protected final CommandNode getCommandNode()

Return the command node

isHidden

protected final boolean isHidden()

Get the hidden state

isDisabled

protected final boolean isDisabled()

Get the grayed state

incMaskLevel

protected final void incMaskLevel()

Increment the mask level

decMaskLevel

protected final void decMaskLevel()

Decrement the mask level

incGrayLevel

protected final void incGrayLevel()

Increment the gray level

decGrayLevel

protected final void decGrayLevel()

Decrement the gray level

propertySetChanged

public void propertySetChanged(PropertySetEvent ev)

Model changed. If this is overridden, be sure to call the superclass.

Specified by:

propertySetChanged in interface PropertySetListener

Parameters:

ev - more information about the event

hiddenStateChanged

protected abstract void hiddenStateChanged(boolean nowHidden)

The hidden state has changed.

disabledStateChanged

protected abstract void disabledStateChanged(boolean nowDisabled)

The gray state has changed.

getCardinality

protected abstract int getCardinality()

Get the cardinality (number of swing objects this node represents). Most things have a cardinality of 1. Groups have variable cardinality. Containers have a cardinality of 1.

dump

public static void dump(AbstractBuilderNode node)

Dump subgraph to standard error
