Package org.springframework.beans

@NonNullApi @NonNullFields package org.springframework.beans

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).

InvalidPropertyException	Exception thrown when referring to an invalid bean property.
Mergeable	Interface representing an object whose value set can be merged with that of a parent object.
MethodInvocationException	Thrown when a bean property getter or setter method throws an exception, analogous to an InvocationTargetException.
MutablePropertyValues	The default implementation of the PropertyValues interface.
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 is not writable (typically because there is 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.
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.

TypeConverter	Interface that defines type conversion methods.
TypeConverterSupport	Base implementation of the TypeConverter interface, using a package-private delegate.
