getPropertyChangeListeners

public PropertyChangeListener[] getPropertyChangeListeners(String propertyName)

hasListeners

public boolean hasListeners(String propertyName)

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener listener)

removePropertyChangeListener

public void removePropertyChangeListener(String propertyName,
                                         PropertyChangeListener listener)

setProperty

public void setProperty(String key,
                        Object value)

Set property key to value.

This implementation checks that a write method is not available for the property using JavaBeans introspection, and stores the property in UnboundBean.properties only if a write method does not exist. This implementation also fires a PropertyChangeEvent for the property.

Specified by:

setProperty in interface BeanInterface

Overrides:

setProperty in class UnboundBean

Parameters:

key -

value -
