Interface ValueChangeListener

public interface ValueChangeListener

ValueChangeListener is used internally by JThreadKit. You will only use this interface on rare occasions when you need to access instances of ValueMonitor that have been constructed by a superclass you are extending.

Used to monitor changes in the value stored in a ValueMonitor. See addValueChangeListener.

Here's a typical use:

ValueMonitor valMon = //... valMon.addValueChangeListener(new ValueChangeListener() { public void valueChanged(ValueMonitor valMon, int newValue) { // Value changed, do something quickly... // ... } });

Method Summary

void	valueChanged(ValueMonitor valMon, int newValue) This method is called every time the value stored inside an instance of ValueMonitor changes.

Method Detail

valueChanged

public void valueChanged(ValueMonitor valMon,
                         int newValue)

This method is called every time the value stored inside an instance of ValueMonitor changes. This method is called by the thread that just changed the value--while calling this method, this thread continues to hold the exclusive lock on the object returned by ValueMonitor.getLockObject(). In light of this, implementations of this method should do their work quickly (and without making method calls that potentially block!).

Parameters:

valMon - the particular ValueMonitor that was just changed (a single listener can monitor multiple instances of ValueMonitor).

newValue - the new value as a result of this change (no need to query the instance).
