Class DataRange

java.lang.Object

org.das2.graph.DataRange

All Implemented Interfaces:

java.lang.Cloneable

Direct Known Subclasses:

DataRange.Animation

public class DataRange
extends java.lang.Object
implements java.lang.Cloneable

A DataRange is a mutable object representing a range, used to bind to axes together. This creates something of a "hard link" between two axes, unlike the "soft link" which is created when BeansBinding is used. Note the DatumRange object, found in org.das2.datum is immutable.

addUpdateListener

public void addUpdateListener(DasUpdateListener l)

removeUpdateListener

public void removeUpdateListener(DasUpdateListener l)

fireUpdate

protected void fireUpdate()

popHistory

protected void popHistory(int ipop)

pop ipop items off the history list. This is used by the history menu

Parameters:

ipop - number of items to pop off the list.

getAnimationDataRange

public static DataRange getAnimationDataRange(DatumRange range,
                                              boolean log)

mutatorLock

protected DasAxis.Lock mutatorLock()

valueIsAdjusting

public boolean valueIsAdjusting()

true if a lock is out and an object is rapidly mutating the object. clients listening for property changes can safely ignore property changes while valueIsAdjusting is true, as they should receive a final propertyChangeEvent after the lock is released. (note it's not clear who is responsible for this. See http://www.das2.org/wiki/index.php/Das2.valueIsAdjusting)

Returns:

true if a lock is out and an object is rapidly mutating the object.
