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

 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);

This module is used to represent a Java Manifest.

A constant denoting the main section of the manifest.

Exported by default.

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, and the remaining sections will be sorted in name order.

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);

Debian::Javahelper::Java(3) - had parse/write methods for manifests. Debian::Javahelper::ManifestSection(3) - for how sections are handled.
