Writing your own processor

Writing processor is as easy as implementing com.cognifide.slice.mapper.api.processor.FieldProcessor interface.

...

• accepts - this method decides if the field can be mapped by this processor
• mapResourceToField - this method returns a value which is set to specified field.

Registering your processor

 To register custom FieldProcessor insert following code in your implementation of com.google.inject.Module.

...

Writing your own post-processor

Writing post-processor is essentially the same as writing processor. Instead of implementing com.cognifide.slice.mapper.api.processor.FieldProcessor you should implement com.cognifide.slice.mapper.api.processor.FieldPostProcessor.

...

public class ReverseTextFieldPostProcessor implements FieldPostProcessor {

   @Override
   public boolean accepts(Resource resource, Field field, Object value) {
      return value instanceof String;
   }

   @Override
   public Object processValue(Resource resource, Field field, Object value) {
      return StringUtils.reverse((String) value);
   }
}

Registering your post-processor

To register custom FieldPostProcessor insert following code in your implementation of com.google.inject.Module.
