Class ActionErrors

java.lang.Object
  org.apache.struts.action.ActionMessages
      org.apache.struts.action.ActionErrors

All Implemented Interfaces:

java.io.Serializable

public class ActionErrors
extends ActionMessages
implements java.io.Serializable

A class that encapsulates the error messages being reported by the validate() method of an ActionForm. Validation errors are either global to the entire ActionForm bean they are associated with, or they are specific to a particular bean property (and, therefore, a particular input field on the corresponding form).

Each individual error is described by an ActionMessage object, which contains a message key (to be looked up in an appropriate message resources database), and up to four placeholder arguments used for parametric substitution in the resulting message.

IMPLEMENTATION NOTE - It is assumed that these objects are created and manipulated only within the context of a single thread. Therefore, no synchronization is required for access to internal collections.
