Method Detail

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener l)

Description copied from interface: NamedBean

Request a call-back when a bound property changes. Bound properties are the known state, commanded state, user and system names.

Specified by:

addPropertyChangeListener in interface NamedBean

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener l)

Description copied from interface: NamedBean

Remove a request for a call-back when a bound property changes.

Specified by:

removePropertyChangeListener in interface NamedBean

getNumPropertyChangeListeners

public int getNumPropertyChangeListeners()

Number of current listeners. May return -1 if the information is not available for some reason.

Specified by:

getNumPropertyChangeListeners in interface NamedBean

getSystemName

public String getSystemName()

Description copied from interface: NamedBean

Get a system-specific name. This encodes the hardware addressing information.

Specified by:

getSystemName in interface NamedBean

getUserName

public String getUserName()

Specified by:

getUserName in interface NamedBean

setUserName

public void setUserName(String s)

Specified by:

setUserName in interface NamedBean

firePropertyChange

protected void firePropertyChange(String p,
                                  Object old,
                                  Object n)

dispose

public void dispose()

Description copied from interface: NamedBean

Deactivate this object, so that it releases as many resources as possible and no longer effects others.

For example, if this object has listeners, after a call to this method it should no longer notify those listeners. Any native or system-wide resources it maintains should be released, including threads, files, etc.

It is an error to invoke any other methods on this object once dispose() has been called. Note, however, that there is no guarantee about behavior in that case.

Afterwards, references to this object may still exist elsewhere, preventing its garbage collection. But it's formally dead, and shouldn't be keeping any other objects alive. Therefore, this method should null out any references to other objects that this NamedBean contained.
