public static java.lang.String PROPERTY_DATUMRANGE

Constructor Detail

DataRange

public DataRange(DasAxis parent,
                 Datum min,
                 Datum max,
                 boolean log)

Method Detail

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object

isLog

public boolean isLog()

resetRange

public void resetRange(DatumRange range)

setLog

public void setLog(boolean log)

set the log property. If log is true and max or min is zero or negative, then the values are reset to make them valid.

Parameters:

getDatumRange

public DatumRange getDatumRange()

setUnits

public void setUnits(Units newUnits)

setMinimum

public void setMinimum(Datum min)

setMaximum

public void setMaximum(Datum max)

clearHistory

public void setRangeForward()

addPropertyChangeListener

public void addPropertyChangeListener(java.lang.String propertyName,
                                      java.beans.PropertyChangeListener listener)

removePropertyChangeListener

public void removePropertyChangeListener(java.lang.String propertyName,
                                         java.beans.PropertyChangeListener listener)

firePropertyChange

protected void firePropertyChange(java.lang.String propertyName,
                                  double oldValue,
                                  double newValue)

firePropertyChange

protected void firePropertyChange(java.lang.String propertyName,
                                  boolean oldValue,
                                  boolean newValue)

firePropertyChange

protected void firePropertyChange(java.lang.String propertyName,
                                  java.lang.Object oldValue,
                                  java.lang.Object newValue)

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

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)
