Class CMSCompressedDataParser

  • public class CMSCompressedDataParser
extends CMSContentInfoParser
    Class for reading a CMS Compressed Data stream. 
         CMSCompressedDataParser cp = new CMSCompressedDataParser(inputStream);
      
     process(cp.getContent(new ZlibExpanderProvider()).getContentStream());
    Note: this class does not introduce buffering - if you are processing large files you should create the parser with: 
          CMSCompressedDataParser     ep = new CMSCompressedDataParser(new BufferedInputStream(inputStream, bufSize));
    where bufSize is a suitably large buffer size.
