A package fragment is a portion of the workspace corresponding to an entire package, or to a portion thereof. The distinction between a package fragment and a package is that a package with some name is the union of all package fragments in the class path which have the same name.

Package fragments elements need to be opened before they can be navigated or manipulated. The children are of type ICompilationUnit (representing a source file) or IClassFile (representing a binary class file). The children are listed in no particular order.
