  • Constructor Details

    • XZCompressorOutputStream

      public XZCompressorOutputStream(OutputStream outputStream) throws IOException
      Creates a new XZ compressor using the default LZMA2 options. This is equivalent to XZCompressorOutputStream(outputStream, 6).
      Parameters:
      outputStream - the stream to wrap
      Throws:
      IOException - on error
    • XZCompressorOutputStream

      public XZCompressorOutputStream(OutputStream outputStream, int preset) throws IOException
      Creates a new XZ compressor using the specified LZMA2 preset level.

      The presets 0-3 are fast presets with medium compression. The presets 4-6 are fairly slow presets with high compression. The default preset is 6.

      The presets 7-9 are like the preset 6 but use bigger dictionaries and have higher compressor and decompressor memory requirements. Unless the uncompressed size of the file exceeds 8 MiB, 16 MiB, or 32 MiB, it is waste of memory to use the presets 7, 8, or 9, respectively.

      Parameters:
      outputStream - the stream to wrap
      preset - the preset
      Throws:
      IOException - on error
