NAME

       Debian::Javahelper::Manifest - Javahelper representation of a Jar Manifest

SYNOPSIS

	use Debian::Javahelper::Java;

	my $manifest = ...;
	my $main_sec = $manifest->get_section(MAIN_SECTION);
	# Create if it does not exist.
	my $file_sec = $manifest->get_section("java/lang/Object.class", 1);

DESCRIPTION

       This module is used to represent a Java Manifest.

   Constants
       MAIN_SECTION
	   A constant denoting the main section of the manifest.

	   Exported by default.

   Methods
       Debian::Javahelper::Manifest->new()
	   Creates a new manifest. It will only contain the main section with the Manifest-Version attribute.

       $manifest->get_section($name[, $create])
	   Returns the section denoted by $name. If this section does not exist, then it will either return undef or (if $create is a truth-value)
	   create a new empty section with that name.

	   Use the MAIN_SECTION constant to access the main section of the manifest.

       $manifest->get_sections()
	   Returns a list of all sections in $manifest. The main section will always be the first in the list, but the remaining sections can come
	   in any order (and this order can change in later invocations).

	   Modifying the list will not change which sections are present in $manifest, but modifying a section in this list will also update the
	   section in the manifest.

       $manifest->merge($other)
	   Merge all entries in $other into $manifest. All sections in $other will be added to $manifest if they are not already present.

	   If an attribute in a given section is only present in one of the two manifests, then that attribute and its value will be in $manifest
	   after merge returns.

	   If the attribute in a given section is present in both manifests, then the value from $other will be used.

	   This can be used to make a deep copy a manifest:

	    my $copy = Debian::Javahelper::Manifest->new();
	    $copy->merge($orig);
