Field Detail

$TYPE

public static final Node.NType $TYPE

tool

protected Tool tool

The tool to which this tool node is associated.

Constructor Detail

ToolRoot

public ToolRoot()

Method Detail

attributeChanged

protected abstract void attributeChanged(Attribute[] b)

This method is invoked to notify the tool root about modifications of attributes of the tool target.

Parameters:

b - an array of attributes which have changed

executeWithWriteLock

public void executeWithWriteLock(Command command,
                        EditEvent event)

Executes the given command in the main thread of the workbench and with a write-lock on the graph. The context-argument of the command's run-method will be the given event, the arg-argument will be this.

Parameters:

command - a command to be executed

event - the event, it is used as Context

getToolTarget

public java.lang.Object getToolTarget()

Returns the target object of the tool.

Returns:

the target object of the tool

See Also:

Tool.getObject()

initialize

protected boolean initialize(Tool tool)

Initializes this tool root. This method initializes the field tool with the given tool.

Parameters:

tool - the tool to which this tool root is associated

Returns:

true if this tool root actually shall be used for the tool, false if it shall not be used (e.g., if the actual tool target cannot be manipulated by the tool graph of this tool root).

isTargetNode

public boolean isTargetNode()

Returns true iff the target object of the tool is a node.

Returns:

is the target object a node?
