Method Details
- properties
  
  public SortedMap<String,String> properties()
  
  Get the set of options for the pack and unpack engines.
  
  Specified by:
  
  properties in interface Pack200.Unpacker
  
  Returns:
  
  A sorted association of option key strings to option values.
- toString

  toString in class Object
- unpack
  
  public void unpack(InputStream in, JarOutputStream out) throws IOException
  
  Takes a packed-stream InputStream, and writes to a JarOutputStream. Internally the entire buffer must be read, it may be more efficient to read the packed-stream to a file and pass the File object, in the alternate method described below.
  Closes its input but not its output. (The output can accumulate more elements.)
  
  Specified by:
  
  unpack in interface Pack200.Unpacker
  
  Parameters:
  
  in - an InputStream.
  
  out - a JarOutputStream.
  
  Throws:
  
  IOException - if an error is encountered.
- unpack
  
  public void unpack(File in, JarOutputStream out) throws IOException
  
  Takes an input File containing the pack file, and generates a JarOutputStream.
  Does not close its output. (The output can accumulate more elements.)
  
  Specified by:
  
  unpack in interface Pack200.Unpacker
  
  Parameters:
  
  in - a File.
  
  out - a JarOutputStream.
  
  Throws:
  
  IOException - if an error is encountered.
