    public abstract class AbstractPropertyBindingResult

extends AbstractBindingResult

Abstract base class for `BindingResult` implementations that work with Spring's `PropertyAccessor` mechanism. Pre-implements field access through delegation to the corresponding PropertyAccessor methods.

Constructor Detail

### AbstractPropertyBindingResult

    protected AbstractPropertyBindingResult(String objectName)

  Create a new AbstractPropertyBindingResult instance.

  Parameters:
    `objectName` - the name of the target object
  See Also:
    `DefaultMessageCodesResolver`

Method Detail

### initConversion

    public void initConversion(ConversionService conversionService)

### getPropertyEditorRegistry

    public PropertyEditorRegistry getPropertyEditorRegistry()

  Returns the underlying PropertyAccessor.

  Specified by:
    `getPropertyEditorRegistry` in interface `BindingResult`
  Overrides:
    `getPropertyEditorRegistry` in class `AbstractBindingResult`
  Returns:
    the PropertyEditorRegistry, or `null` if none available for this BindingResult
  See Also:
    `getPropertyAccessor()`

### canonicalFieldName

    protected String canonicalFieldName(String field)

  Returns the canonical property name.

  Overrides:
    `canonicalFieldName` in class `AbstractErrors`
  Parameters:
    `field` - the original field name
  Returns:
    the canonical field name
  See Also:
    `PropertyAccessorUtils.canonicalPropertyName(java.lang.String)`

### getFieldType

    public Class<?> getFieldType(String field)

  Determines the field type from the property type.

  Specified by:
    `getFieldType` in interface `Errors`
  Overrides:
    `getFieldType` in class `AbstractBindingResult`
  Parameters:
    `field` - the field name
  Returns:
    the type of the field, or `null` if not determinable
  See Also:
    `getPropertyAccessor()`

### getActualFieldValue

    protected Object getActualFieldValue(String field)

  Fetches the field value from the PropertyAccessor.

  Specified by:
    `getActualFieldValue` in class `AbstractBindingResult`
  Parameters:
    `field` - the field to check
  Returns:
    the current value of the field
  See Also:
    `getPropertyAccessor()`

### formatFieldValue

    protected Object formatFieldValue(String field,
                                      Object value)

  Formats the field value based on registered PropertyEditors.

  Overrides:
    `formatFieldValue` in class `AbstractBindingResult`
  Parameters:
    `field` - the field to check
    `value` - the value of the field (either a rejected value other than from a binding error, or an actual field value)
  Returns:
    the formatted value
  See Also:
    `getCustomEditor(java.lang.String)`

### getCustomEditor

    protected PropertyEditor getCustomEditor(String fixedField)

  Retrieve the custom PropertyEditor for the given field, if any.

  Parameters:
    `fixedField` - the fully qualified field name
  Returns:
    the custom PropertyEditor, or `null`

### findEditor

    public PropertyEditor findEditor(String field,
                                     Class<?> valueType)

  This implementation exposes a PropertyEditor adapter for a Formatter, if applicable.

  Specified by:
    `findEditor` in interface `BindingResult`
  Overrides:
    `findEditor` in class `AbstractBindingResult`
  Parameters:
    `field` - the path of the property (name or nested path), or `null` if looking for an editor for all properties of the given type
    `valueType` - the type of the property (can be `null` if a property is given but should be specified in any case for consistency checking)
  Returns:
    the registered editor, or `null` if none

### getPropertyAccessor

    public abstract ConfigurablePropertyAccessor getPropertyAccessor()

  Provide the PropertyAccessor to work with, according to the concrete strategy of access.

  Note that a PropertyAccessor used by a BindingResult should always have its "extractOldValueForEditor" flag set to "true" by default, since this is typically possible without side effects for model objects that serve as data binding target.

    `ConfigurablePropertyAccessor.setExtractOldValueForEditor(boolean)`
