Class BusinessRuleValidationTemplate

java.lang.Object
  org.mod4j.runtime.validation.BusinessRuleValidationTemplate

public class BusinessRuleValidationTemplate
extends java.lang.Object

Template class that simplifies business rule validation. The central method is execute(org.mod4j.runtime.validation.BusinessRuleValidationCallback), supporting validations implementing the BusinessRuleValidationCallback interface. It provides for the creation of an Errors object for storing all errors found while validating fields of a particular object in the BusinessRuleValidationCallback.doValidate(Object, Errors) method. After all validations are executed and the results collected in the Errors object and if one or more errors are found, a BusinessRuleException is thrown that wraps the the BindException object that implements the Errors object is thrown as an exception.
