org.springframework.beans.AbstractPropertyAccessor

org.springframework.beans.BeanWrapperImpl

All Implemented Interfaces:

BeanWrapper, ConfigurablePropertyAccessor, PropertyAccessor, PropertyEditorRegistry, TypeConverter

public class BeanWrapperImpl
extends AbstractPropertyAccessor
implements BeanWrapper

Default BeanWrapper implementation that should be sufficient for all typical use cases. Caches introspection results for efficiency.

Note: Auto-registers default property editors from the org.springframework.beans.propertyeditors package, which apply in addition to the JDK's standard PropertyEditors. Applications can call the PropertyEditorRegistrySupport.registerCustomEditor(Class, java.beans.PropertyEditor) method to register an editor for a particular instance (i.e. they are not shared across the application). See the base class PropertyEditorRegistrySupport for details.

BeanWrapperImpl will convert collection and array values to the corresponding target collections or arrays, if necessary. Custom property editors that deal with collections or arrays can either be written via PropertyEditor's setValue, or against a comma-delimited String via setAsText, as String arrays are converted in such a format if the array itself is not assignable.

NOTE: As of Spring 2.5, this is - for almost all purposes - an internal class. It is just public in order to allow for access from other framework packages. For standard application access purposes, use the PropertyAccessorFactory.forBeanPropertyAccess(java.lang.Object) factory method instead.
