Interface Summary

AppletInitializer	This interface is a mechanism for the initialization of a Java Bean that is also an Applet.
BeanInfo	BeanInfo can be implemented in order to provide explicit information to the Introspector.
Customizer	You may explicitly provide a Customizer for your Bean class, which allows you complete control of the editing of the Bean.
DesignMode	BeanContextChild implementors implement this to get information about whether they are in a design time or runtime environment.
ExceptionListener	This interface allows a class to monitor internal exceptions, to try to recover from them.
PropertyChangeListener	PropertyChangeListener allows a class to monitor properties of a Bean for changes.
PropertyEditor	PropertyEditors are custom GUI editors for specific types of values.
VetoableChangeListener	VetoableChangeListener allows a class to monitor proposed changes to properties of a Bean and, if desired, prevent them from occurring.
Visibility	Visibility is an interface a Bean may implement so that the environment can tell the Bean whether there is a GUI or not, and so that the Bean can tell the environment whether it needs one or can run without one.

Class Summary

BeanDescriptor	BeanDescriptor describes general information about a Bean, plus stores the Bean's Class and it's customizer's Class.
Beans	Beans provides some helper methods that allow the basic operations of Bean-ness.
DefaultPersistenceDelegate	DefaultPersistenceDelegate is a PersistenceDelegate implementation that can be used to serialize objects which adhere to the Java Beans naming convention.
Encoder
EventHandler	EventHandler forms a bridge between dynamically created listeners and arbitrary properties and methods.
EventSetDescriptor	EventSetDescriptor describes the hookup between an event source class and an event listener class.
Expression	An Expression captures the execution of an object method that returns a value.
FeatureDescriptor	FeatureDescriptor is the common superclass for all JavaBeans Descriptor classes.
IndexedPropertyChangeEvent	This is like a PropertyChangeEvent, but also carries with it the index of the property which changed.
IndexedPropertyDescriptor	IndexedPropertyDescriptor describes information about a JavaBean indexed property, by which we mean an array-like property that has been exposed via a pair of get and set methods and another pair that allows you to get to the property by an index.
Introspector	Introspector is the class that does the bulk of the design-time work in Java Beans.
MethodDescriptor	MethodDescriptor describes information about a JavaBeans method.
ParameterDescriptor	ParameterDescriptor represents a single parameter to a method.
PersistenceDelegate	A PersistenceDelegate describes how a another object has to constructed and transformed in order to create a complete replicate.
PropertyChangeEvent	PropertyChangeEvents are fired in the PropertyChange and VetoableChange event classes.
PropertyChangeListenerProxy	This class provides an extension to PropertyChangeListener - associating a name with the listener.
PropertyChangeSupport	PropertyChangeSupport makes it easy to fire property change events and handle listeners.
PropertyDescriptor	PropertyDescriptor describes information about a JavaBean property, by which we mean a property that has been exposed via a pair of get and set methods.
PropertyEditorManager	PropertyEditorManager is used to find property editors for various types (not necessarily Beans).
PropertyEditorSupport	PropertyEditorSupport helps with PropertyEditors, implementing base functionality that they usually must have but which is a pain to implement.
SimpleBeanInfo	SimpleBeanInfo is a class you may extend to more easily provide select information to the Introspector.
Statement	A Statement captures the execution of an object method.
VetoableChangeListenerProxy	This class provides an extension to VetoableChangeListener - associating a name with the listener.
VetoableChangeSupport	VetoableChangeSupport makes it easy to fire vetoable change events and handle listeners.
XMLDecoder	The XMLDecoder reads XML data that is structured according to this DTD and creates objects according to the content.
XMLEncoder	This class uses the PersistenceDelegate and Encoder infrastructure to generate an XML representation of the objects it serializes.

Exception Summary

IntrospectionException	IntrospectionException is thrown when the Introspector fails.
PropertyVetoException	PropertyVetoException is thrown when a VetoableChangeListener doesn't like the proposed change.

Annotation Types Summary

ConstructorProperties	An annotation used to associate the parameters of a constructor with the accessor methods that later provide access to these values.
Transient	Indicates that an attribute called "transient" should be declared with the given value when the Introspector constructs a PropertyDescriptor or EventSetDescriptor classes associated with the annotated code element.
