      public HuffmanTable(int numberOfCodeStructuresInTable, int[] numberOfBitsInPrefix, int[] numberOfBitsInEntireCode, int[] tableModeSwitch, int[] baseValueRepresentedByBaseCode, long[] baseCode)

      Construct a Huffman Table from the supplied data as read from an SCP-ECG file.

      Parameters:
      numberOfCodeStructuresInTable - the number of codes (i.e. the size of all the array parameters)
      numberOfBitsInPrefix - for each code, the number of prefix bits for each code (i.e. the Huffman code)
      numberOfBitsInEntireCode - for each code, if > numberOfBitsInPrefix, used to find the number of original bits encoded
      tableModeSwitch - for each code, a flag to indicate to switch to another table (1 indicates no switch)
      baseValueRepresentedByBaseCode - for each code, the value that the code represents
      baseCode - the codes (with the order of bits reversed)
