Interface java.beans.beancontext.BeanContextChild

public interface BeanContextChild

JavaBeans wishing to be nested within, and obtain a reference to their execution environment, or context, as defined by the BeanContext sub-interface shall implement this interface.

Conformant BeanContexts shall as a side effect of adding a BeanContextChild object shall pass a reference to itself via the setBeanContext() method of this interface.

Note that a BeanContextChild may refuse a change in state by throwing PropertyVetoedException in response.

In order for persistence mechanisms to function properly on BeanContextChild instances across a broad variety of scenarios, implementing classes of this interface are required to define as transient, any or all fields, or instance variables, that may contain, or represent, references to the nesting BeanContext instance, Delegates indirectly obtained via the nesting BeanContext's java.util.Aggregate interface, or other resources obtained from the BeanContext via any unspecified mechanisms.

Since:

JDK1.2

BEANCONTEXT_PROPERTYNAME

addPropertyChangeListener(PropertyChangeListener)

add a property change listener to this bean child

addVetoableChangeListener(VetoableChangeListener)

add a vetoable change listener to this child

getBeanContext()

removePropertyChangeListener(PropertyChangeListener)

remove a property change listener to this bean child

removeVetoableChangeListener(VetoableChangeListener)

remove a vetoable change listener to this child

setBeanContext(BeanContext)

Objects that implement this interface, shall fire a java.beans.PropertyChangeEvent, with parameters:

public static final String BEANCONTEXT_PROPERTYNAME

public abstract void setBeanContext(BeanContext bc) throws PropertyVetoException

Objects that implement this interface, shall fire a java.beans.PropertyChangeEvent, with parameters:

Parameters:

propertyName - java.beans.BeanContextChild.PROPERTYNAME

oldValue - the previous nesting BeanContext instance, or null

newValue - the current nesting BeanContext instance, or null

A change in the value of the nesting BeanContext property of this BeanContextChild may be vetoed by throwing the appropriate exception.

public abstract BeanContext getBeanContext()
