This technical article explains how the Java Mobile Sensor API (JSR 256 for Java Platform, Micro Edition) enables Java MIDlets to talk to the physical and virtual sensors available on a device.
Debian::Javahelper::Java(3) Javahelper Debian::Javahelper::Java(3)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:
- ",
join("
- ", @paths), "
";
my @packnames = find_package_for_existing_files("/bin/ls",
"/bin/bash");
print "/bin/ls and /bin/bash are installed via: ",
join(", ", @packnames), "
";
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.
