Class FieldError

java.lang.Object
  org.springframework.context.support.DefaultMessageSourceResolvable
      org.springframework.validation.ObjectError
          org.springframework.validation.FieldError

All Implemented Interfaces:: Serializable, MessageSourceResolvable

public class FieldError
extends ObjectError
extends ObjectError

Encapsulates a field error, that is, a reason for rejecting a specific field value.

See the DefaultMessageCodesResolver javadoc for details on how a message code list is built for a FieldError.

Since:: 10.03.2003
Author:: Rod Johnson, Juergen Hoeller
See Also:: DefaultMessageCodesResolver, Serialized Form

Constructor Summary

FieldError(String objectName, String field, Object rejectedValue, boolean bindingFailure, String[] codes, Object[] arguments, String defaultMessage)
          Create a new FieldError instance.

Method Summary

boolean equals(Object other)


String getField()
          Return the affected field of the object.

Object getRejectedValue()
          Return the rejected field value.

int hashCode()


boolean isBindingFailure()
          Return whether this error represents a binding failure (like a type mismatch); else, it is a validation failure.

String toString()
          Default implementation exposes the attributes of this MessageSourceResolvable.

Constructor Detail

FieldError

public FieldError(String objectName,
                  String field,
                  Object rejectedValue,
                  boolean bindingFailure,
                  String[] codes,
                  Object[] arguments,
                  String defaultMessage)

Create a new FieldError instance.

Parameters:: objectName - the name of the affected object; field - the affected field of the object; rejectedValue - the rejected field value; bindingFailure - whether this error represents a binding failure (like a type mismatch); else, it is a validation failure; codes - the codes to be used to resolve this message; arguments - the array of arguments to be used to resolve this message; defaultMessage - the default message to be used to resolve this message

Method Detail

getField

public String getField()

Return the affected field of the object.

getRejectedValue

public Object getRejectedValue()

Return the rejected field value.

isBindingFailure

public boolean isBindingFailure()

Return whether this error represents a binding failure (like a type mismatch); else, it is a validation failure.

toString

public String toString()

Description copied from class: DefaultMessageSourceResolvable

Default implementation exposes the attributes of this MessageSourceResolvable. To be overridden in more specific subclasses, potentially including the resolvable content through resolvableToString().

Overrides:: toString in class ObjectError

See Also:: DefaultMessageSourceResolvable.resolvableToString()

equals

public boolean equals(Object other)

Overrides:: equals in class ObjectError

hashCode

public int hashCode()

Overrides:: hashCode in class ObjectError
