An EventSetDescriptor describes a group of events that a given Java bean fires.class
AnExpression
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()"
.class
The FeatureDescriptor class is the common baseclass for PropertyDescriptor, EventSetDescriptor, and MethodDescriptor, etc.class
An "IndexedPropertyChange" event gets delivered whenever a component that conforms to the JavaBeans specification (a "bean") changes a bound indexed property.class
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.class
Thrown when an exception happens during Introspection.class
The Introspector class provides a standard way for tools to learn about the properties, events, and methods supported by a target Java Bean.class
A MethodDescriptor describes a particular method that a Java Bean supports for external access from other components.class
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.class
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.class
A "PropertyChange" event gets delivered whenever a bean changes a "bound" or "constrained" property.class
A class which extends theEventListenerProxy
specifically for adding aPropertyChangeListener
with a "bound" property.class
This is a utility class that can be used by beans that support bound properties.class
A PropertyDescriptor describes one property that a Java Bean exports via a pair of accessor methods.class
The PropertyEditorManager can be used to locate a property editor for any given type name.class
This is a support class to help build property editors.class
A PropertyVetoException is thrown when a proposed change to a property represents an unacceptable value.class
This is a support class to make it easier for people to provide BeanInfo classes.class
AStatement
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)"
.class
A class which extends theEventListenerProxy
specifically for adding aVetoableChangeListener
with a "constrained" property.class
This is a utility class that can be used by beans that support constrained properties.class
TheXMLDecoder
class is used to read XML documents created using theXMLEncoder
and is used just like theObjectInputStream
.class

class is a complementary alternative to theObjectOutputStream
and can used to generate a textual representation of a JavaBean in the same way that theObjectOutputStream
can be used to create binary representation ofSerializable
