This sequencer generates a graph structure that maps to the files and folders in the ZIP file. An example (listed in the JCR document view) from sequencing a ZIP file written into /a/foo and containing one file, /x/y/z.txt is provided below:

<foo jcr:primaryType="zip:file"

     jcr:mixinTypes="mode:derived"

     mode:derivedAt="2011-05-13T13:12:03.925Z"

     mode:derivedFrom="/files/docForReferenceGuide.xml" >

  <x jcr:primaryType="nt:folder" 

     jcr:created="2011-05-12T20:07Z"

     jcr:createdBy="currentJcrUser">

    <y jcr:primaryType="nt:folder" 

       jcr:created="2011-05-12T20:09Z"

       jcr:createdBy="currentJcrUser">

      <z.txt jcr:primaryType="nt:file">

        <jcr:content jcr:primaryType="nt:resource"

                     jcr:data="This is the file content"

                     jcr:lastModified="2011-05-12T20:12Z"

                     jcr:lastModifiedBy="currentJcrUser" 

                     jcr:mimeType="text/plain" />

      </z.txt>

    </y>

  </x>         

</foo>

The CND for the zip:file node type is listed below.

[zip:file] > nt:folder, mix:mimeType    

To use this sequencer, simply include the modeshape-sequencer-zip JAR in your application and configure the JcrConfiguration to use this sequencer using something similar to:

JcrConfiguration config = ...


config.sequencer("ZIP Sequencer")

      .usingClass("org.modeshape.sequencer.zip.ZipSequencer")

      .loadedFromClasspath()

      .setDescription("Sequences compressed files to extract the internal file and folder structure")

      .sequencingFrom("//(*.(zip|gz|jar|war|ear)[*])/jcr:content[@jcr:data]")

      .andOutputtingTo("/zips/$1");
