Constructor Detail

PersistenceElementImpl

public PersistenceElementImpl()

Create new PersistenceElementImpl with no corresponding name. This constructor should only be used for cloning and archiving.

PersistenceElementImpl

public PersistenceElementImpl(String name)

Creates new PersistenceElementImpl with the corresponding name

Parameters:

name - the name of the element

Method Detail

attachToElement

public void attachToElement(PersistenceElement element)

Called to attach the implementation to a specific element. Will be called in the element's constructor. Allows implementors of this interface to store a reference to the holder class, useful for implementing the property change listeners.

Specified by:

attachToElement in interface PersistenceElement.Impl

Parameters:

element - the element to attach to

firePropertyChange

protected void firePropertyChange(String name,
                                  Object o,
                                  Object n)

Fires property change event.

Parameters:

name - property name

o - old value

n - new value

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener l)

Add a property change listener.

Specified by:

addPropertyChangeListener in interface PersistenceElement.Impl

Parameters:

l - the listener to add

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener l)

Remove a property change listener.

Specified by:

removePropertyChangeListener in interface PersistenceElement.Impl

Parameters:

l - the listener to remove

fireVetoableChange

protected void fireVetoableChange(String name,
                                  Object o,
                                  Object n)
                           throws PropertyVetoException

Fires vetoable change event.

Parameters:

name - property name

o - old value

n - new value

Throws:

PropertyVetoException - when the change is vetoed by a listener

addVetoableChangeListener

public void addVetoableChangeListener(VetoableChangeListener l)

Add a vetoable change listener.

Specified by:

addVetoableChangeListener in interface PersistenceElement.Impl

Parameters:

l - the listener to add

removeVetoableChangeListener

public void removeVetoableChangeListener(VetoableChangeListener l)

Remove a vetoable change listener.

Specified by:

removeVetoableChangeListener in interface PersistenceElement.Impl

Parameters:

l - the listener to remove

getName

public String getName()

Get the name of this persistence element.

Specified by:

getName in interface PersistenceElement.Impl

Returns:

the name

setName

public void setName(String name)
             throws ModelException

Set the name of this persistence element.

Specified by:

setName in interface PersistenceElement.Impl

Parameters:

name - the name

Throws:

ModelException - if impossible
