Description

Interface Summary

BeanMetadataElement	Interface to be implemented by bean metadata elements that carry a configuration source object.
BeanWrapper	The central interface of Spring's low-level JavaBeans infrastructure.
ConfigurablePropertyAccessor	Interface that encapsulates configuration methods for a PropertyAccessor.
Mergeable	Interface representing an object whose value set can be merged with that of a parent object.
PropertyAccessor	Common interface for classes that can access named properties (such as bean properties of an object or fields in an object) Serves as base interface for BeanWrapper.
PropertyEditorRegistrar	Interface for strategies that register custom property editors with a property editor registry.
PropertyEditorRegistry	Encapsulates methods for registering JavaBeans PropertyEditors.
PropertyValues	Holder containing 0 or more PropertyValue objects, typically comprising one update.
TypeConverter	Interface that defines type conversion methods.

Class Summary

AbstractPropertyAccessor	Abstract implementation of the ConfigurablePropertyAccessor interface.
BeanUtils	Static convenience methods for JavaBeans: for instantiating beans, checking bean property types, copying bean properties, etc.
BeanWrapperImpl	Default BeanWrapper implementation that should be sufficient for all typical use cases.
CachedIntrospectionResults	Internal class that caches JavaBeans PropertyDescriptor information for a Java class.
DirectFieldAccessor	PropertyAccessor implementation that directly accesses instance fields.
MutablePropertyValues	Default implementation of the PropertyValues interface.
PropertyAccessorUtils	Utility methods for classes that perform bean property access according to the PropertyAccessor interface.
PropertyEditorRegistrySupport	Base implementation of the PropertyEditorRegistry interface.
PropertyValue	Class to hold information and value for an individual property.
PropertyValuesEditor	Editor for PropertyValues objects.
SimpleTypeConverter	Simple implementation of the TypeConverter interface that does not operate on any specific target object.

Exception Summary

BeanInstantiationException	Exception thrown when instantiation of a bean failed.
BeansException	Abstract superclass for all exceptions thrown in the beans package and subpackages.
FatalBeanException	Thrown on an unrecoverable problem encountered in the beans packages or sub-packages, e.g. bad class or field.
InvalidPropertyException	Exception thrown when referring to an invalid bean property.
MethodInvocationException	Thrown when a bean property getter or setter method throws an exception, analogous to an InvocationTargetException.
NotReadablePropertyException	Exception thrown on an attempt to get the value of a property that isn't readable, because there's no getter method.
NotWritablePropertyException	Exception thrown on an attempt to set the value of a property that isn't writable, because there's no setter method.
NullValueInNestedPathException	Exception thrown when navigation of a valid nested property path encounters a NullPointerException.
PropertyAccessException	Superclass for exceptions related to a property access, such as type mismatch or invocation target exception.
PropertyBatchUpdateException	Combined exception, composed of individual PropertyAccessException instances.
TypeMismatchException	Exception thrown on a type mismatch when trying to set a bean property.

Package org.springframework.beans Description

This package contains interfaces and classes for manipulating Java beans. It is used by most other Spring packages.

A BeanWrapper object may be used to set and get bean properties, singly or in bulk.

The classes in this package are discussed in Chapter 11 of Expert One-On-One J2EE Design and Development by Rod Johnson (Wrox, 2002).
