org.springframework.webflow.engine.support.DefaultTransitionCriteria
Transition criteria that tests the value of an expression. The expression is used to express a condition that guards transition execution in a web flow. Expressions will be evaluated against the request context. Boolean, string, and custom TransitonCriteria evaluation results are supported. @author Keith Donald @author Erwin Vervaet
