    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.

Since:
  2.0

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.

  See Also:
    `ConfigurablePropertyAccessor.setExtractOldValueForEditor(boolean)`
