Examples of com.bbn.openmap.layer.vpf.LibrarySelectionTable

com.bbn.openmap.layer.vpf.LibrarySelectionTable
Reads the VPF LibraryAttribute table and constructs CoverageAttributeTables for each of the library coverages (north america, browse, etc) that exist.
NOTE: This class maintains a whole bunch of cached information, and also hangs onto references to classes that cache even more information. When using this class, you are much better off sharing an instance of this class, rather than creating multiple instantiations of it for the same VPF data directory. @see CoverageAttributeTable
