  See Also:
    `DefaultMessageCodesResolver`

    public void setMessageCodesResolver(MessageCodesResolver messageCodesResolver)

  Set the strategy to use for resolving errors into message codes. Default is DefaultMessageCodesResolver.

  See Also:
    `DefaultMessageCodesResolver`

### getMessageCodesResolver

    public MessageCodesResolver getMessageCodesResolver()

  Return the strategy to use for resolving errors into message codes.

### getObjectName

    public String getObjectName()

  Description copied from interface: `Errors`
  Return the name of the bound root object.

  Specified by:
    `getObjectName` in interface `Errors`

### reject

    public void reject(String errorCode,
                       Object[] errorArgs,
                       String defaultMessage)

  Description copied from interface: `Errors`
  Register a global error for the entire target object, using the given error description.

  Specified by:
    `reject` in interface `Errors`
  Parameters:
    `errorCode` - error code, interpretable as a message key
    `errorArgs` - error arguments, for argument binding via MessageFormat (can be `null`)
    `defaultMessage` - fallback default message

### rejectValue

    public void rejectValue(String field,
                            String errorCode,
                            Object[] errorArgs,
                            String defaultMessage)

  Description copied from interface: `Errors`
  Register a field error for the specified field of the current object (respecting the current nested path, if any), using the given error description.

  The field name may be `null` or empty String to indicate the current object itself rather than a field of it. This may result in a corresponding field error within the nested object graph or a global error if the current object is the top object.

  Specified by:
    `rejectValue` in interface `Errors`
  Parameters:
    `field` - the field name (may be `null` or empty String)

### addAllErrors

    public void addAllErrors(Errors errors)

  Description copied from interface: `Errors`

    the resolved message codes
  See Also:
    `setMessageCodesResolver(org.springframework.validation.MessageCodesResolver)`

### getFieldErrors

    public List getFieldErrors(String field)

  Description copied from interface: `Errors`
  Get all errors associated with the given field.

  Implementations should support not only full field names like "name" but also pattern matches like "na*" or "address.*".

  Specified by:
    `getFieldErrors` in interface `Errors`
  Overrides:

### getFieldValue

    public Object getFieldValue(String field)

  Description copied from interface: `Errors`
  Return the current value of the given field, either the current bean property value or a rejected update from the last binding.

  Allows for convenient access to user-specified field values, even if there were type mismatches.

  Specified by:
    `getFieldValue` in interface `Errors`
  Parameters:
    `field` - the field name
  Returns:
    the current value of the given field

### getFieldType

    public Class getFieldType(String field)

  This default implementation determines the type based on the actual field value, if any. Subclasses should override this to determine the type from a descriptor, even for `null` values.

  Specified by:
    `getFieldType` in interface `Errors`
  Overrides:
    `getFieldType` in class `AbstractErrors`
  Parameters:
    `field` - the field name
  Returns:
    the type of the field, or `null` if not determinable
  See Also:
    `getActualFieldValue(java.lang.String)`

### getModel

    public Map getModel()

  Return a model Map for the obtained state, exposing an Errors instance as '`MODEL_KEY_PREFIX` + objectName' and the object itself.

  Note that the Map is constructed every time you're calling this method. Adding things to the map and then re-calling this method will not work.

  The attributes in the model Map returned by this method are usually included in the ModelAndView for a form view that uses Spring's bind tag, which needs access to the Errors instance. Spring's SimpleFormController will do this for you when rendering its form or success view. When building the ModelAndView yourself, you need to include the attributes from the model Map returned by this method yourself.

  Specified by:
    `getModel` in interface `BindingResult`
  See Also:
    `getObjectName()`, `BindingResult.MODEL_KEY_PREFIX`, `ModelAndView`, `BindTag`, `SimpleFormController`

### getRawFieldValue

    public Object getRawFieldValue(String field)

  Description copied from interface: `BindingResult`
  Extract the raw field value for the given field. Typically used for comparison purposes.

  Specified by:
    `getRawFieldValue` in interface `BindingResult`
  Parameters:
    `field` - the field to check
  Returns:
    the current value of the field in its raw form, or `null` if not known

### findEditor

    public PropertyEditor findEditor(String field,
                                     Class valueType)

  This implementation delegates to the `PropertyEditorRegistry`'s editor lookup facility, if available.

  Specified by:
    `findEditor` in interface `BindingResult`
  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

### getPropertyEditorRegistry

    public PropertyEditorRegistry getPropertyEditorRegistry()

  This implementation returns `null`.

  Specified by:
    `getPropertyEditorRegistry` in interface `BindingResult`
  Returns:
    the PropertyEditorRegistry, or `null` if none available for this BindingResult

### recordSuppressedField

    public void recordSuppressedField(String field)

  Mark the specified disallowed field as suppressed.

  The data binder invokes this for each field value that was detected to target a disallowed field.

  Specified by:
    `recordSuppressedField` in interface `BindingResult`
  See Also:
    `DataBinder.setAllowedFields(java.lang.String[])`

### getSuppressedFields

    public String[] getSuppressedFields()

  Return the list of fields that were suppressed during the bind process.

  Can be used to determine whether any field values were targetting disallowed fields.

  Specified by:
    `getSuppressedFields` in interface `BindingResult`
  See Also:
    `DataBinder.setAllowedFields(java.lang.String[])`

### equals

    public boolean equals(Object other)

  Return the wrapped target object.

  Specified by:
    `getTarget` in interface `BindingResult`

### getActualFieldValue

    protected abstract Object getActualFieldValue(String field)

  Extract the actual field value for the given field.

  Parameters:
    `field` - the field to check
  Returns:
    the current value of the field

### formatFieldValue

    protected Object formatFieldValue(String field,
                                      Object value)

  Format the given value for the specified field.

  The default implementation simply returns the field value as-is.

  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
