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