Method Summary

void	addPropertyChangeListener(java.beans.PropertyChangeListener l) Overridden to add a listener to the contained bean when the first change listener is added.
void	addPropertyChangeListener(java.lang.String propertyName, java.beans.PropertyChangeListener l) Adds a property change listener that will be notified whenever the specified property changes.

Constructor Detail

BeanMetaObject

public BeanMetaObject(java.lang.Object bean,
                      MetaClass metaClass)

Method Detail

release

public void release()

Releases any internal resources that may be held by the underlying implementation. This clears the internal data structures and releases any listeners that were added to the underlying bean.

Specified by:

release in interface MetaObject

Overrides:

release in class AbstractMetaObject

setProperty

public void setProperty(java.lang.String name,
                        java.lang.Object value)

Overridden to prevent redundant change notifications from being delivered by the bean.

Specified by:

setProperty in interface MetaObject

Overrides:

setProperty in class AbstractMetaObject

addPropertyChangeListener

public void addPropertyChangeListener(java.beans.PropertyChangeListener l)

Overridden to add a listener to the contained bean when the first change listener is added.

Specified by:

addPropertyChangeListener in interface MetaObject

Specified by:

addPropertyChangeListener in interface StandardBean

Overrides:

addPropertyChangeListener in class BeanChangeSupport

addPropertyChangeListener

public void addPropertyChangeListener(java.lang.String propertyName,
                                      java.beans.PropertyChangeListener l)

Adds a property change listener that will be notified whenever the specified property changes.

Specified by:

addPropertyChangeListener in interface MetaObject

Specified by:

addPropertyChangeListener in interface StandardBean

Overrides:

addPropertyChangeListener in class BeanChangeSupport

getBean

protected java.lang.Object getBean()

Provides access to the bean to local MetaKit and possibly subclasses.

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

propertyChanged

public void propertyChanged(java.lang.String name,
                            java.lang.Object oldValue)

Notifies listeners that the property value has changed outside of the BeanMetaObject's control.

dispatchEvent

protected void dispatchEvent(java.beans.PropertyChangeEvent event)

Back-door into the event delivery chain.

setPropertyValue

protected java.lang.Object setPropertyValue(java.lang.String name,
                                            java.lang.Object value)

Used a bean-inspector to set the property and does some checks to make sure property changes are propagated correctly even if the bean's internal reference hasn't changed.

Specified by:

setPropertyValue in class AbstractMetaObject

getPropertyValue

protected java.lang.Object getPropertyValue(java.lang.String name)

Overridden by subclasses to provide implementation-specific field-level access.

Specified by:

getPropertyValue in class AbstractMetaObject

createListMutator

protected ListMutator createListMutator(java.lang.String name,
                                        ListPropertyType type)

Creates a BeanListMutator that provides advanced access to multi-valued bean properties.

Overrides:

createListMutator in class AbstractMetaObject

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
