IlvDefaultPropertyManager

public IlvDefaultPropertyManager(Object sourceBean)

Method Detail

setProperty

public Object setProperty(String key,
                          Object value)

Changes one of the properties of this object. If the value has changed, a PropertyChangeEvent is sent to property change listeners.

Specified by:

setProperty in interface IlvPropertyManager

Parameters:

key - The non-null property key.

value - An Object value. If it is equal to null, the property with the specified key will be removed.

Returns:

The previous value of the property.

getProperty

public Object getProperty(String key)

removePropertyChangeListener(java.beans.PropertyChangeListener)

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener listener)

Removes the specified PropertyChangeListener from the listener list, so that it no longer receives PropertyChangeEvent.

Specified by:

removePropertyChangeListener in interface IlvPropertyManager

Parameters:

listener - The listener to remove.

See Also:

addPropertyChangeListener(java.beans.PropertyChangeListener)

firePropertyChange

public void firePropertyChange(String key,
                               Object oldValue,
                               Object newValue)

Support method for notifying bound property changes. If oldValue and newValue are equal, this method does nothing. Otherwise, a PropertyChange event is fired to each listener.

In an implementing class, it is recommended to provide methods for accessing main properties, taking care to trigger the corresponding PropertyChange event. For example, here's how to write a bound property method changing the value of a Name string property.

 public void setName(String newName) {
     Stirng oldName = name;
     name = newName;
     firePropertyChange(NAME_PROPERTY, oldName, newName);
 }
 static final String NAME_PROPERTY = "Name";
 private string name;
 

Parameters:

key - The key of the property that was changed.

oldValue - The old value of the property.

newValue - The new value of the property.
