Examples of org.apache.tapestry5.services.ComponentMethodAdvice

org.apache.tapestry5.services.FieldValidatorSource
An object that receives control around an "advised" method of a component. The advise can query or even replace method parameters. After invoking {@link org.apache.tapestry5.services.ComponentMethodInvocation#proceed()}, the advice may query and override thrown exceptions or the return value of the invocation. @see TransformMethod#addAdvice(ComponentMethodAdvice) @see ComponentInstanceOperation @deprecated Deprecated in 5.3 @see org.apache.tapestry5.plastic.PlasticClass @see org.apache.tapestry5.plastic.PlasticMethod @see org.apache.tapestry5.plastic.MethodAdvice
