DirectFieldAccessor

extends AbstractPropertyAccessor

java.lang.Object
↳	org.springframework.beans.PropertyEditorRegistrySupport
	↳	org.springframework.beans.AbstractPropertyAccessor
		↳	org.springframework.beans.DirectFieldAccessor

Class Overview

PropertyAccessor implementation that directly accesses instance fields. Allows for direct binding to fields instead of going through JavaBean setters.

This implementation just supports fields in the actual target object. It is not able to traverse nested fields.

A DirectFieldAccessor's default for the "extractOldValueForEditor" setting is "true", since a field can always be read without side effects.

Public Constructors

public DirectFieldAccessor (Object target)

Also: SpringBeans

Create a new DirectFieldAccessor for the given target object.

Parameters

target	the target object to access

Public Methods

public T convertIfNecessary (Object value, Class<T> requiredType, MethodParameter methodParam)

Throws

TypeMismatchException

public Class getPropertyType (String propertyName)

Also: SpringBeans

Determine the property type for the given property path.

Called by findCustomEditor(Class, String) if no required type has been specified, to be able to find a type-specific editor even if just given a property path.

The default implementation always returns null. BeanWrapperImpl overrides this with the standard getPropertyType method as defined by the BeanWrapper interface.

Parameters

propertyName	the property path to determine the type for

Returns

the type of the property, or null if not determinable

Throws

BeansException

public TypeDescriptor getPropertyTypeDescriptor (String propertyName)

Also: SpringBeans

Throws

BeansException

public Object getPropertyValue (String propertyName)

Also: SpringBeans

Actually get the value of a property.

Parameters

propertyName	name of the property to get the value of

Returns

the value of the property

Throws

BeansException

public boolean isReadableProperty (String propertyName)

Also: SpringBeans

Throws

BeansException

public boolean isWritableProperty (String propertyName)

Also: SpringBeans

Throws

BeansException

public void setPropertyValue (String propertyName, Object newValue)

Also: SpringBeans

Actually set a property value.

Parameters

propertyName	name of the property to set value of
newValue	the new value

Throws

BeansException
