Constructor Detail

ZipPacker.ZipPackerInputStream

public ZipPacker.ZipPackerInputStream(java.io.InputStream in,
                                      int bufferSize)

Creates a ZipPackerInputStream that wrapps an InputStream.

Parameters:

in - the InputStream that should be used to read the zipped data to from.

bufferSize - the initial size of the internal buffer. The size of the buffer is increased as needed. Each time the buffer needs to be resized its size is increased by bufferSize / 2 bytes.
