## org.springframework.web.bind
Class EscapedErrors

    java.lang.Object
      org.springframework.web.bind.EscapedErrors

All Implemented Interfaces:
  Errors

    public class EscapedErrors

extends Object
implements Errors

Errors wrapper that adds automatic HTML escaping to the wrapped instance, for convenient usage in HTML views. Can be retrieved easily via RequestContext's `getErrors` method.

Note that BindTag does not use this class to avoid unnecessary creation of ObjectError instances. It just escapes the messages and values that get copied into the respective BindStatus instance.

Constructor Detail

### EscapedErrors

    public EscapedErrors(Errors source)

  Create a new EscapedErrors instance for the given source instance.

Method Detail

### getSource

    public Errors getSource()

### 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)`

### reject

    public void reject(String errorCode,

    public void rejectValue(String field,
                            String errorCode)

  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:
