Class ELBinder

java.lang.Object

org.seedstack.seed.el.internal.ELBinder

public class ELBinder
extends Object

ELBinder provides methods to bind an ELInterceptor on a given annotation.

The evaluation of the EL provided by the annotation value will be evaluated regarding the ELBinder.ExecutionPolicy, ie. before the method is proceed, after, or both.

Example:

     public class MyModule extends AbstractModule {

         @Override
         protected void configure() {
             // the EL will be evaluated before the method proceed
             new ELBinder(this.binder())
                 .bindELAnnotation(MyELAnnotation.class, ELBinder.ExecutionPolicy.BEFORE);
         }
     }
 

By default, if no policy is given the EL will be evaluated after the method proceed.
