Method Detail

blockCount

int blockCount()

The minimum number of long blocks to encode in a single call.

valueCount

int valueCount()

The number of values that can be stored in blockCount() long blocks.

encode

void encode(long[] values,
          int valuesOffset,

Parameters:

blocks - the long blocks that hold packed integer values

blocksOffset - the offset where to start writing blocks

values - the values buffer

valuesOffset - the offset where to start reading values

iterations - controls how much data to encode
