Class NamedMappingTransformer<T>

java.lang.Object

org.incenp.obofoundry.sssom.transform.NamedMappingTransformer<T>

Type Parameters:

T - The type of object to transform the mapping into.

All Implemented Interfaces:

IMappingTransformer<T>

public class NamedMappingTransformer<T>
extends Object
implements IMappingTransformer<T>

A mapping transformer that has a string representation. This class merely wraps an existing transformer. It is mostly intended for debugging, so that transformers created using lambda functions can still be displayed in a readable form.

Example, for a transformer that produces basic string representations of mappings:

 IMappingTransformer<String> myTransformer = new NamedMappingTransformer<String>("mapping-to-string",
         (mapping) -> String.format("%s -[%s]-> %s", mapping.getSubjectId(), mapping.getPredicateId(),
                 mapping.getObjectId()));
