Method Detail

swap

void swap(long a,
          long b,
          int ngramOrder)

Swaps values at offsets a and b.

Parameters:

a -

b -

ngramOrder -

getCompressed

BitList getCompressed(long offset,
                      int ngramOrder)

Compresses the value at the given offset into a list of bits.

Parameters:

offset -

ngramOrder -

Returns:

decompress

void decompress(BitStream bits,
                int ngramOrder,
                boolean justConsume,
                V outputVal)

Reads and decompresses from the bit stream bits.

Parameters:

bits -

ngramOrder -

justConsume - If true, nothing is returned, and the function simply consumes the appropriate number of bits from the BitStream.

clearStorageAfterCompression

void clearStorageAfterCompression(int ngramOrder)
