Method Detail

add

void add(Comparable e)

freeze

ArrayTable.Column freeze(int ordinal,
                         int[] sources)

Freezes the contents of this value set into a column, optionally re-ordering if sources is specified.

chooseRep

ArrayTable.Representation chooseRep(int ordinal)

toLong

private long toLong(Object o)

canBeLong

private boolean canBeLong(Object o)

chooseFixedRep

private ArrayTable.Representation chooseFixedRep(int ordinal,
                                                 Primitive p,
                                                 long min,
                                                 long max)

Chooses a representation for a fixed-precision primitive type (boolean, byte, char, short, int, long).

Parameters:

ordinal - Ordinal of this column in table

p - Type that values are to be returned as (not necessarily the same as they will be stored)

min - Minimum value to be encoded

max - Maximum value to be encoded (inclusive)

abs2

private static int abs2(int v)

Two's complement absolute on int value.

abs2

private static long abs2(long v)

Two's complement absolute on long value.
