java.beans (Java Platform SE 6)

This documentation differs from the official API. Jadeite adds extra features to the API including: variable font sizes, constructions examples, placeholders for classes and methods, and auto-generated “See Also” links. Additionally it is missing some items found in standard Javadoc documentation, including: generics type information, “Deprecated” tags and comments, “See Also” links, along with other minor differences. Please send any questions or feedback to bam@cs.cmu.edu.

Package java.beans

Interface Summary
AppletInitializer	This interface is designed to work in collusion with java.beans.Beans.instantiate.
BeanInfo	A bean implementor who wishes to provide explicit information about their bean may provide a BeanInfo class that implements this BeanInfo interface and provides explicit information about the methods, properties, events, etc, of their bean.
Customizer	A customizer class provides a complete custom GUI for customizing a target Java Bean.
DesignMode	This interface is intended to be implemented by, or delegated from, instances of java.beans.beancontext.BeanContext, in order to propagate to its nested hierarchy of java.beans.beancontext.BeanContextChild instances, the current "designTime" property.
ExceptionListener	An ExceptionListener is notified of internal exceptions.
PropertyChangeListener	A "PropertyChange" event gets fired whenever a bean changes a "bound" property.
PropertyEditor	A PropertyEditor class provides support for GUIs that want to allow users to edit a property value of a given type.
VetoableChangeListener	A VetoableChange event gets fired whenever a bean changes a "constrained" property.
Visibility	Under some circumstances a bean may be run on servers where a GUI is not available.

Interface Summary

AppletInitializer

Customizer

A customizer class provides a complete custom GUI for customizing a target Java Bean.

DesignMode

This interface is intended to be implemented by, or delegated from, instances of java.beans.beancontext.BeanContext, in order to propagate to its nested hierarchy of java.beans.beancontext.BeanContextChild instances, the current "designTime" property.

ExceptionListener

An ExceptionListener is notified of internal exceptions.

Class Summary
BeanDescriptor	A BeanDescriptor provides global information about a "bean", including its Java class, its displayName, etc.
Beans	This class provides some general purpose beans control methods.
DefaultPersistenceDelegate	The `DefaultPersistenceDelegate` is a concrete implementation of the abstract `PersistenceDelegate` class and is the delegate used by default for classes about which no information is available.
Encoder	An `Encoder` is a class which can be used to create files or streams that encode the state of a collection of JavaBeans in terms of their public APIs.
EventHandler	The `EventHandler` class provides support for dynamically generating event listeners whose methods execute a simple statement involving an incoming event object and a target object.
EventSetDescriptor	An EventSetDescriptor describes a group of events that a given Java bean fires.
Expression	An `Expression` object represents a primitive expression in which a single method is applied to a target and a set of arguments to return a result - as in `"a.getFoo()"`.
FeatureDescriptor	The FeatureDescriptor class is the common baseclass for PropertyDescriptor, EventSetDescriptor, and MethodDescriptor, etc.
IndexedPropertyChangeEvent	An "IndexedPropertyChange" event gets delivered whenever a component that conforms to the JavaBeans specification (a "bean") changes a bound indexed property.
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	The Introspector class provides a standard way for tools to learn about the properties, events, and methods supported by a target Java Bean.
MethodDescriptor	A MethodDescriptor describes a particular method that a Java Bean supports for external access from other components.
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	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	A "PropertyChange" event gets delivered whenever a bean changes a "bound" or "constrained" property.
PropertyChangeListenerProxy	A class which extends the `EventListenerProxy` specifically for adding a named `PropertyChangeListener`.
PropertyChangeSupport	This is a utility class that can be used by beans that support bound properties.
PropertyDescriptor	A PropertyDescriptor describes one property that a Java Bean exports via a pair of accessor methods.
PropertyEditorManager	The PropertyEditorManager can be used to locate a property editor for any given type name.
PropertyEditorSupport	This is a support class to help build property editors.
SimpleBeanInfo	This is a support class to make it easier for people to provide BeanInfo classes.
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	A class which extends the `EventListenerProxy` specifically for associating a `VetoableChangeListener` with a "constrained" property.
VetoableChangeSupport	This is a utility class that can be used by beans that support constrained properties.
XMLDecoder	The `XMLDecoder` class is used to read XML documents created using the `XMLEncoder` and is used just like the `ObjectInputStream`.
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.
