public class ActionErrors extends ActionMessages implements 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.
