Class RequestParamProducer

java.lang.Object
  org.jboss.seam.servlet.http.RequestParamProducer

public class RequestParamProducer
extends Object

A producer for a String bean qualified @RequestParam.

Provides a producer method that retrieves the value of the specified request parameter from ServletRequest.getParameter(String) and makes it available as a dependent-scoped bean of type String qualified @RequestParam. The name of the request parameter to lookup is either the value of the @RequestParam annotation or, if the annotation value is empty, the name of the injection point (e.g., the field name).

If the request parameter is not present, and the injection point is annotated with @DefaultValue, the value of the @DefaultValue annotation is returned instead. If @DefaultValue is not present, null is returned.
