# Debian::Javahelper::ManifestSection(3)

Javahelper representation of a section in a Jar Manifest

## NAME

Debian::Javahelper::ManifestSection - Javahelper representation of a section in a Jar Manifest

## SYNOPSIS

```
 use Debian::Javahelper::Manifest;

 my $main_sec = $manifest->get_section(MAIN_SECTION, 1);
 # set the Main-Class attribute
 $main_sec->set_value('Main-Class', 'org.site.app.AppStarter');
 # read the classpath entry - may return undef if the attribute does not exist.
 my $cp = $main_sec->get_value('Class-Path');
 # same as above except $cp will be '' if the attribute does not exist.
 $cp = $main_sec->get_value('Class-Path',  1);
 # returns a list of [$name, $value] pairs - note $name will be in the original
 # case.
 my @att = $main_sec->get_values();
```

## DESCRIPTION

This module is used to represent a Section in a Java Manifest.

### Constants

- MAIN\_SECTION

  A constant denoting the main section of the manifest.

  Exported by default.

### Methods

- Debian::Javahelper::ManifestSection-\>new($name)

  Creates a new section - if **$name** is MAIN\_SECTION, then it will set "Manifest-Version" otherwise it will set "Name" to **$name**.

  Generally you should not need to use this directly! The Debian::Javahelper::Manifest will create sections as they are needed. There is no support for creating a section and then adding it to a manifest after wards.

- $section-\>set\_value($attr, $value)

  Sets the value of **$attr** to **$value**. If **$attr** did not exist in this section then it will be created. **$value** may not contain newlines.

  Note: **$attr** exists if an attribute matches **$attr** ignoring the case of the two. When **$attr** is created, the original case will be stored for later (for writing). Later updates to **$attr** will not affect the original case.

- $section-\>get\_value($attr\[, $empty\])

  Returns the value of **$attr**, long values are merged into a single line. **$attr** is looked up case-insensitively.

  Returns **undef** if **$attr** is not present in the section, unless **$empty** is a truth-value. In this case it will return ''.

- $section-\>**get\_values()**

  Returns all the values in the section in a list of \[$attr, `$value`\] pairs. "Manifest-Version" and "Name" will appear first in this list if they appear in this section, the remaining attributes appears in any order and this order may change.

  Modifying the list or the pairs will *not* affect the attributes in the section.

  Note: The **$attr** part will be the original case of the attribute.
