Interface jclass.chart.Changeable

public interface Changeable
The Changeable interface is used as a template for objects that have a changed flag or changed semantic involving some kind of recalculation. This is very common inside JCChart. All ChartRegion derived objects make use of Changeable, either by directly implementing the interface or by deriving from TrackChange (an abstract class that implements Changeable).

Methods

o getChanged 
 public abstract boolean getChanged()
Gets the value of the Changed property. The Changed property determines whether the object needs to be recalculated.

Returns:
True if the object has been changed and needs recalculation, false otherwise.
o getChanged 
 public abstract boolean getChanged(int mask)
Checks the value of the ChangedFlag property for the existence of the specified mask. The ChangedFlag property determines the type of action (recalc, redraw) that needs to happen to the object.

Returns:
True if the ChangedFlag contains the given mask (e.g. RECALC, REDRAW, etc.), false otherwise.
o isChanged 
 public abstract boolean isChanged()
Gets the value of the Changed property. The Changed property determines whether the object needs to be recalculated.

Returns:
True if the object has been changed and needs recalculation, false otherwise.
o isChanged 
 public abstract boolean isChanged(int mask)
Checks the value of the ChangedFlag property for the existence of the specified mask. The ChangedFlag property determines the type of action (recalc, redraw) that needs to happen to the object.

Returns:
True if the ChangedFlag contains the given mask (e.g. RECALC, REDRAW, etc.), false otherwise.
o setChanged 
 public abstract void setChanged(boolean n,
                                 int cf)
Sets the value of the Changed property and updates the parent object. The Changed property determines whether the object needs to be recalculated.

Parameters:
n - New value for Changed.
cf - Or-ed series of bit flags indicating type of change.
o setChanged 
 public abstract void setChanged(boolean n,
                                 int cf,
                                 boolean updateParent)
Sets the value of the Changed property. The Changed property determines whether the object needs to be recalculated.

Parameters:
n - New value for Changed.
cf - Or-ed series of bit flags indicating type of change.
updateParent - If true, the parent is updated. Otherwise, the parent is not updated. The "update" semantics are up to the implementor
