        Specified by:
        properties in interface Pack200.Unpacker

      • unpack

        public void unpack​(java.io.InputStream in,
                   java.util.jar.JarOutputStream out)
            throws java.io.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:
        java.io.IOException - if an error is encountered.

      • unpack

        public void unpack​(java.io.File in,
                   java.util.jar.JarOutputStream out)
            throws java.io.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:
        java.io.IOException - if an error is encountered.
