SciJava Common is a shared library for SciJava software. It provides a plugin framework, with an extensible mechanism for service discovery, backed by its own annotation processor, so that plugins can be loaded dynamically. It is used by downstream projects in the SciJava ecosystem, such as ImageJ and SCIFIO.

* from {@link ObjectDeletedEvent}s.

* This is useful to retrieve available objects of a particular type. For
* example, the {@link org.scijava.widget.InputHarvester} infrastructure uses it
* to provide a pool of available objects for widgets such as the
* {@link org.scijava.widget.ObjectWidget}, which provide the user with a
* multiple-choice selection.
