Package org.geotoolkit.metadata.iso.extent Description

Extent implementation. An explanation for this package is provided in the OpenGIS® javadoc. The remaining discussion on this page is specific to the Geotk implementation.

Overview
For a global overview of metadata in Geotk, see the Metadata page on the project web site.

Parameterized types
In GeoAPI interfaces, most collections are typed with wildcards, for example Collection<? extends Citation>. The Geotk implementation removes the wildcards and declares Collection<Citation> instead. This allows collections to be live. Consequently it is possible to add new elements directly in an existing collection using code like getCitations().add(myCitation) instead than setting the collection as a whole with setCitations(myCitations).
