## Class BindException

- java.lang.Object
- - java.lang.Throwable
  - - java.lang.Exception
    - - org.springframework.validation.BindException

All Implemented Interfaces:
  Serializable, BindingResult, Errors

    public class BindException
    extends Exception
    implements BindingResult

Thrown when binding errors are considered fatal. Implements the `BindingResult` interface (and its super-interface `Errors`) to allow for the direct analysis of binding errors.

As of Spring 2.0, this is a special-purpose class. Normally, application code will work with the `BindingResult` interface, or with a `DataBinder` that in turn exposes a BindingResult via `DataBinder.getBindingResult()`.

### Constructor Detail

#### BindException

    public BindException(BindingResult bindingResult)

Create a new BindException instance for a BindingResult.

Parameters:
  `bindingResult` - the BindingResult instance to wrap

#### BindException

    public BindException(Object target,
                 String objectName)

Create a new BindException instance for a target bean.

Parameters:
  `target` - target bean to bind onto
  `objectName` - the name of the target object
See Also:
  `BeanPropertyBindingResult`

### Method Detail

#### getBindingResult

    public final BindingResult getBindingResult()

Return the BindingResult that this BindException wraps. Will typically be a BeanPropertyBindingResult.

See Also:
  `BeanPropertyBindingResult`

#### getObjectName

    public String getObjectName()

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

Specified by:
  `getObjectName` in interface `Errors`

#### setNestedPath

    public void setNestedPath(String nestedPath)

Description copied from interface: `Errors`
Allow context to be changed so that standard validators can validate subtrees. Reject calls prepend the given path to the field names.

For example, an address validator could validate the subobject "address" of a customer object.

Specified by:
  `setNestedPath` in interface `Errors`
Parameters:
  `nestedPath` - nested path within this object, e.g. "address" (defaults to "", `null` is also acceptable). Can end with a dot: both "address" and "address." are valid.

#### getNestedPath

    public String getNestedPath()

Description copied from interface: `Errors`
Return the current nested path of this `Errors` object.

Returns a nested path with a dot, i.e. "address.", for easy building of concatenated paths. Default is an empty String.

Specified by:
  `getNestedPath` in interface `Errors`

#### pushNestedPath

    public void pushNestedPath(String subPath)

Description copied from interface: `Errors`
Push the given sub path onto the nested path stack.

A `Errors.popNestedPath()` call will reset the original nested path before the corresponding `pushNestedPath(String)` call.

Using the nested path stack allows to set temporary nested paths for subobjects without having to worry about a temporary path holder.

For example: current path "spouse.", pushNestedPath("child") -> result path "spouse.child."; popNestedPath() -> "spouse." again.

Specified by:
  `pushNestedPath` in interface `Errors`
Parameters:
  `subPath` - the sub path to push onto the nested path stack
See Also:
  `Errors.popNestedPath()`

#### popNestedPath

    public void popNestedPath()
                       throws IllegalStateException

Description copied from interface: `Errors`
Pop the former nested path from the nested path stack.

Specified by:
  `popNestedPath` in interface `Errors`
Throws:
  `IllegalStateException` - if there is no former nested path on the stack
See Also:
  `Errors.pushNestedPath(java.lang.String)`

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

#### getFieldType

    public Class<?> getFieldType(String field)

  the type of the field, or `null` if not determinable

#### getTarget

    public Object getTarget()

Description copied from interface: `BindingResult`
Return the wrapped target object, which may be a bean, an object with public fields, a Map - depending on the concrete binding strategy.

Specified by:
  `getTarget` in interface `BindingResult`

#### getModel

    public Map<String,Object> getModel()

Description copied from interface: `BindingResult`
Return a model Map for the obtained state, exposing a BindingResult instance as '`MODEL_KEY_PREFIX` + objectName' and the object itself as 'objectName'.

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 in a JSP, which needs access to the BindingResult instance. Spring's pre-built form controllers will do this for you when rendering a form view. When building the ModelAndView instance yourself, you need to include the attributes from the model Map returned by this method.

Specified by:
  `getModel` in interface `BindingResult`
