Class AbstractJavaToHostTransformer

java.lang.Object
  com.legstar.coxb.transform.AbstractTransformer
      com.legstar.coxb.transform.AbstractJavaToHostTransformer

All Implemented Interfaces:

IHostTransformer, IJavaToHostTransformer

public abstract class AbstractJavaToHostTransformer
extends AbstractTransformer
implements IJavaToHostTransformer

Generic methods to transform java value object to host data.

Implementing classes should inherit from AbstractJavaToHostTransformer and implement the getBinding method.

This is sample code with dynamic binding:

 public class JavaToHostLsfileaeTransformer extends
         AbstractJavaToHostTransformer {
     public ICobolComplexBinding getBinding() throws BindingException {
         try {
             CComplexReflectBinding binding = new CComplexReflectBinding(
                     new com.legstar.test.coxb.lsfileae.ObjectFactory(),
                     com.legstar.test.coxb.lsfileae.Dfhcommarea.class);
             return binding;
         } catch (ReflectBindingException e) {
             throw new BindingException(e);
         }
     }
 }
 

This is sample code with static binding:

 public class JavaToHostLsfileaeTransformer extends
         AbstractJavaToHostTransformer {
     public ICobolComplexBinding getBinding() throws BindingException {
         return new com.legstar.test.coxb.lsfileae.DfhcommareaBinding();
     }
 }
