Parameters
keySize:int

The size of the key, measure in Integer#BYTES.

addKeyback to summary
pack-priv static <KType> void addKey(KType key, IntArrayList segmentData)

Adds the first key of the current segment to the segment data bytes.

addKeyback to summary
pack-priv static void addKey(int key, IntArrayList segmentData)

Adds the first key of the current segment to the segment data bytes.

addKeyback to summary
pack-priv static void addKey(float key, IntArrayList segmentData)

Adds the first key of the current segment to the segment data bytes.

addKeyback to summary
pack-priv static void addKey(long key, IntArrayList segmentData)

Adds the first key of the current segment to the segment data bytes.

addKeyback to summary
pack-priv static void addKey(double key, IntArrayList segmentData)

Adds the first key of the current segment to the segment data bytes.

addSlopeback to summary
pack-priv static void addSlope(double slope, IntArrayList segmentData, int keySize)

Adds the slope of the current segment to the segment data bytes. The intercept is stored as a float for a key size equal to 1, otherwise it is stored as a double.
