The purpose of the Eclipse-Tools project is to develop plugins for the Eclipse platform.
Currently, the project has released three plugins
The Call Hierarchy plugin is an Eclipse view for showing calls to or calls from a method.
The Implementors plugins add the possibility to jump to a method declaration in a implementation class instead of an interface.
The jumping to implementing methods works for plain Java files. In addition, when associating EJB deployment descriptors with a project, the plugin is made aware of the connection between the EJB interfaces and the implementation class, something which is not specified in the implementation class itself.
