NAME

       Debian::Javahelper::Java - Javahelper core library.

SYNOPSIS

        use Debian::Javahelper::Java;

        my @paths = scan_javadoc("/usr/share/doc/libfreemarker-doc/api/");
        print "Freemarker is linked to the following APIs: \n - ",
              join("\n - ", @paths), "\n";
        my @packnames = find_package_for_existing_files("/bin/ls",
                        "/bin/bash");
        print "/bin/ls and /bin/bash are installed via: ",
              join(", ", @packnames), "\n";

DESCRIPTION

       This module is used by various javahelpers to share common code.

       Please note this API is not stable and backwards compatibility is not guaranteed at the
       current time. Please contact the maintainers if you are interested in a stable API.

   Methods
       scan_javadoc($path)
           Scans the javadoc at $path and returns a list of javadocs it is linked to on the
           system.

           Currently it ignores all javadocs linked via other locations than /usr/share/doc and
           it also makes an assumption that the linked javadoc is in
           /usr/share/doc/<package>/<dir-or-symlink>. Of course, all Java Policy compliant
           packages provide their javadoc from there.

           If /usr/share/doc/<package>/<dir-or-symlink> appears to be a symlink, then it is
           followed (except for default-jdk-doc).

       find_package_for_existing_files(@files)
           Consults dpkg(1) to see which packages provides @files and returns this list. All
           entries in @files must exists (but is not required to be files) and should not be used
           on a directory.

           Furthermore all entries must be given with absolute path.

       parse_manifest_fd($fd, $filename)
           Parses a manifest from $fd, which must be a readable filehandle, and returns a
           Debian::Javahelper::Manifest.

           $filename is only used to report parsing errors and should be something that
           identifies the source of $fd.

       write_manifest_fd($manifest, $fd, $filename)
           Writes $manifest to the writable filehandle $fd. $manifest must be a
           Debian::Javahelper::Manifest.

           $filename is only used to report errors and should be something that identifies $fd.

       write_manifest_section_fd($section, $fd, $filename)
           Writes $section to the writable filehandle $fd. $section must be a
           Debian::Javahelper::ManifestSection.

           $filename is only used to report errors and should be something that identifies $fd.

           NB: Helper - Not exported.

       slurp_file($file)
           Reads all lines in $file and returns them as a list.

           NB: Helper - Not exported.
