IndexedPropertyChangeEvent sample code for java.beans.IndexedPropertyChangeEvent definition code for java.beans.IndexedPropertyChangeEvent An "IndexedPropertyChange" event gets delivered whenever a component that conforms to the JavaBeans specification (a "bean") changes a bound indexed property.
IndexedPropertyDescriptor sample code for java.beans.IndexedPropertyDescriptor definition code for java.beans.IndexedPropertyDescriptor An IndexedPropertyDescriptor describes a property that acts like an array and has an indexed read and/or indexed write method to access specific elements of the array.
Introspector sample code for java.beans.Introspector definition code for java.beans.Introspector The Introspector class provides a standard way for tools to learn about the properties, events, and methods supported by a target Java Bean.
MethodDescriptor sample code for java.beans.MethodDescriptor definition code for java.beans.MethodDescriptor A MethodDescriptor describes a particular method that a Java Bean supports for external access from other components.
ParameterDescriptor sample code for java.beans.ParameterDescriptor definition code for java.beans.ParameterDescriptor The ParameterDescriptor class allows bean implementors to provide additional information on each of their parameters, beyond the low level type information provided by the java.lang.reflect.Method class.
PersistenceDelegate sample code for java.beans.PersistenceDelegate definition code for java.beans.PersistenceDelegate The PersistenceDelegate class takes the responsibility for expressing the state of an instance of a given class in terms of the methods in the class's public API.
PropertyChangeEvent sample code for java.beans.PropertyChangeEvent definition code for java.beans.PropertyChangeEvent A "PropertyChange" event gets delivered whenever a bean changes a "bound" or "constrained" property.
PropertyChangeListenerProxy sample code for java.beans.PropertyChangeListenerProxy definition code for java.beans.PropertyChangeListenerProxy A class which extends the EventListenerProxy specifically for adding a named PropertyChangeListener.
PropertyChangeSupport sample code for java.beans.PropertyChangeSupport definition code for java.beans.PropertyChangeSupport This is a utility class that can be used by beans that support bound properties.
PropertyDescriptor sample code for java.beans.PropertyDescriptor definition code for java.beans.PropertyDescriptor A PropertyDescriptor describes one property that a Java Bean exports via a pair of accessor methods.
PropertyEditorManager sample code for java.beans.PropertyEditorManager definition code for java.beans.PropertyEditorManager The PropertyEditorManager can be used to locate a property editor for any given type name.
PropertyEditorSupport sample code for java.beans.PropertyEditorSupport definition code for java.beans.PropertyEditorSupport This is a support class to help build property editors.
SimpleBeanInfo sample code for java.beans.SimpleBeanInfo definition code for java.beans.SimpleBeanInfo This is a support class to make it easier for people to provide BeanInfo classes.
Statement sample code for java.beans.Statement definition code for java.beans.Statement A Statement object represents a primitive statement in which a single method is applied to a target and a set of arguments - as in "a.setFoo(b)".
VetoableChangeListenerProxy sample code for java.beans.VetoableChangeListenerProxy definition code for java.beans.VetoableChangeListenerProxy A class which extends the EventListenerProxy specifically for associating a VetoableChangeListener with a "constrained" property.
VetoableChangeSupport sample code for java.beans.VetoableChangeSupport definition code for java.beans.VetoableChangeSupport This is a utility class that can be used by beans that support constrained properties.
XMLDecoder sample code for java.beans.XMLDecoder definition code for java.beans.XMLDecoder The XMLDecoder class is used to read XML documents created using the XMLEncoder and is used just like the ObjectInputStream.
XMLEncoder sample code for java.beans.XMLEncoder definition code for java.beans.XMLEncoder The XMLEncoder class is a complementary alternative to the ObjectOutputStream and can used to generate a textual representation of a JavaBean in the same way that the ObjectOutputStream can be used to create binary representation of Serializable objects.
