Constructor Detail

DoubleSerializer

public DoubleSerializer()

Creates a DoubleSerializer that allows uses 8 bytes to represent a double, with no loss of precision.

DoubleSerializer

public DoubleSerializer(double precision,
                        boolean optimizePositive)

Creates a DoubleSerializer that allows uses 1-10 bytes to represent a double, with a loss of precision. The double is multiplied by the specified precision, then cast to a long and serialized with LongSerializer. LongSerializer uses 1-8 bytes from 0 to 7205794037927935 with "optimize positive" and -3602897018963968 to 3602897018963967 without. If a double multiplied by the precision would fall out these values, it will take 9 or 10 bytes to serialize and it may be better to use the other DoubleSerializer constructor.
