All Implemented Interfaces:

public class PkgMap
extends AbstractFileCreatorAdapter

pkgmap is an ASCII file that provides a complete listing of the package contents. It is automatically generated by pkgmk(1) using the information in the prototype(4) file. Representation of a package map file (called "pkgmap" on the filesystem). The pkgmap file is a packing list, where each item in the package is defined and its size and checksum are stored. The size and checksum help in determining that the package has not been tampered with. The various items in the pkgmap are recognized by their ftype entry as shown here. See sun docs http://www.cs.biu.ac.il/cgi-bin/man?pkgmap+4 and http://www.sun.com/bigadmin/features/techtips/package_components.jsp http://www.softpanorama.org/Solaris/Packages/index.shtml.
