Modifier and Type	Method	Description
protected Object	clone()	Answers a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.
boolean	equals(Object o)	Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison.
protected void	finalize()	Deprecated, for removal: This API element is subject to removal in a future version. May cause performance issues, deadlocks and hangs.
final Class<? extends Object>	getClass()	Answers the unique instance of java.lang.Class which represents the class of the receiver.
int	hashCode()	Answers an integer hash code for the receiver.
final void	notify()	Causes one thread which is waiting on the receiver to be made ready to run.
final void	notifyAll()	Causes all threads which are waiting on the receiver to be made ready to run.
String	toString()	Answers a string containing a concise, human-readable description of the receiver.
final void	wait()	Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by notify or notifyAll).
final void	wait(long time)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.

Method Details

getNodeDimensions

public abstract Rectangle getNodeDimensions(Object value,
 int row,
 int depth,
 boolean expanded,
 Rectangle bounds)

Returns, by reference in bounds, the size and x origin to place value at. The calling method is responsible for determining the Y location. If bounds is null, a newly created Rectangle should be returned, otherwise the value should be placed in bounds and returned.

Parameters:

value - the value to be represented

row - row being queried

depth - the depth of the row

expanded - true if row is expanded, false otherwise

bounds - a Rectangle containing the size needed to represent value

Returns:

a Rectangle containing the node dimensions, or null if node has no dimension
