public class ReflectiveVisitorHelper
extends Object

Helper implementation for a reflective visitor. Mainly for internal use within the framework.

To use, call invokeVisit, passing a Visitor object and the data argument to accept (double-dispatch). For example:

   public String styleValue(Object value) {
     reflectiveVistorSupport.invokeVisit(this, value)
   }
  
   // visit call back will be invoked via reflection
   String visit(<valueType> arg) {
     // process argument of type <valueType>
   }
 

See the DefaultValueStyler class for a concrete usage of this visitor helper.

Note: Copied from Spring 2.5 to avoid redoing work using this.

Since:

1.2.2
