Overview

MavenJnlpFamily

Encapsulates a single MavenJnlp Family of versioned jnlps.

Jnlp::MavenJnlpFamily.new(base_url, family_path)

Example:

require 'jnlp'
mjf = Jnlp::MavenJnlpFamily.new('http://jnlp.concord.org', '/dev/org/concord/maven-jnlp/all-otrunk-snapshot')

mjf = Jnlp::MavenJnlpFamily.new('http://jnlp.concord.org', '/dev/org/concord/maven-jnlp/all-otrunk-snapshot', 
  { :versions => ['0.1.0-20100513.161426', '0.1.0-20100513.154925'] })

You can pass in an options hash to limit the number of versioned jnlps parsed:

Example

mjf = Jnlp::MavenJnlpFamily.new('http://jnlp.concord.org', '/dev/org/concord/maven-jnlp/all-otrunk-snapshot', 
     { :versions => ['0.1.0-20100513.161426', '0.1.0-20100513.154925'] })

mjf.versions.length
=> 2
