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.
