    • setCompressionThreshold

      public void setCompressionThreshold(int to)
      Set the compression threshold to the given number of bytes. This transcoder will attempt to compress any data being stored that's larger than this.
      Parameters:
      to - the number of bytes
    • getCompressMode

      public CompressionMode getCompressMode()
    • setCompressionMode

      public void setCompressionMode(CompressionMode compressMode)
    • setCharset

      public void setCharset(String to)
      Set the character set for string value transcoding (defaults to UTF-8).
    • serialize

      protected byte[] serialize(Object o)
      Get the bytes representing the given serialized object.
    • deserialize

      protected Object deserialize(byte[] in)
      Get the object represented by the given serialized bytes.
    • compress

      public final byte[] compress(byte[] in)
      Compress the given array of bytes.
    • zipCompress

      private byte[] zipCompress(byte[] in)
    • gzipCompress

      private static byte[] gzipCompress(byte[] in)
    • decompress

      protected byte[] decompress(byte[] in)
      Decompress the given array of bytes.
      Returns:
      null if the bytes cannot be decompressed
    • zipDecompress

      private byte[] zipDecompress(byte[] in)
    • gzipDecompress

      private byte[] gzipDecompress(byte[] in)
    • decodeString

      protected String decodeString(byte[] data)
      Decode the string with the current character set.
    • encodeString

      protected byte[] encodeString(String in)
      Encode a string into the current character set.
