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.

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.

Exception Summary

IntrospectionException Thrown when an exception happens during Introspection.
PropertyVetoException A PropertyVetoException is thrown when a proposed change to a property represents an unacceptable value.
