Work in progress

Features are grouped according to the interested actor :

• The end user uses existing discoverers through Eclipse workspace features
  
• The adopter uses existing discoverers through a dedicated Eclipse/Java API
  
• The adopter develop new discoverers through a dedicated Eclipse/Java API

Developing a new Discoverer

Basics concepts

The framework proposes a Java interface org.eclipse.modisco.infra.discoverymanager.core.Discoverer<T> that every discoverer must implement.

 public interface Discoverer<T> {
    public boolean isApplicableTo(final T source);
    public IStatus discoverElement(final T source) throws DiscoveryException;
 }

• isApplicableTo method : Determines if the source object can be handled by the discoverer. Each discoverer has to implement this method with its own criteria to filter the selected object. If the source object is managed by this discoverer, the discoverer menu will be available in the pop-up menu when users click with the contextual button (at the condition there is no parameter with required property value to true), and in the discoverer launch configuration types.
• discoverElement method : Generic method for launching a discovery from a source element.
• additional discovery parameters values (input or output) should be managed using fields and methods annotated with org.eclipse.modisco.infra.discoverymanager.core.annotations.Parameter annotation.

Annotating your method/field as parameters of the discovery will enable generic catalog API (see below) and so some client generic behavior (e.g. launchconfig feature for end user).
