Value Engineer Factory

Implementing a Value Engineer

Interface: de.espirit.firstspirit.client.access.editor.ValueEngineerFactory
Developer API documentation: ValueEngineerFactory<T, F extends GomFormElement>

The value engineer factory class is responsible for instantiating an object of a type which implements ValueEngineer<T>, binding the input component's GOM form element definition class to the input component's value engineer class.

Parameterization:

  • T must correspond to the component value type used as the working value in the input component.
  • F extends GomFormElement must correspond to the GOM form element definition used for the input component.

Example

/**
* Value engineer factory that creates a value engineer for the input component "Point"
* and configures that value engineer object with a fitting value engineer context object.
*
* Point: Working component value used by SiteArchitect and ContentCreator gadget classes for the input component
* GomPoint: GOM form definition class for "Point"
* PointValueEngineer: Value engineer class for "Point"
*/
public class PointValueEngineerFactory implements ValueEngineerFactory<Point, GomPoint> {

@Override
public Class<Point> getType() {
return Point.class;
}

@Override
public ValueEngineer<Point> create(final ValueEngineerContext<GomPoint> context) {
return new PointValueEngineer(context);
}
}
