Constructor Summary

FloatSerializer()
Creates a FloatSerializer that allows uses 4 bytes to represent a float, with no loss of precision.

FloatSerializer(float precision, boolean optimizePositive)
Creates a FloatSerializer that allows uses 1-5 bytes to represent a float, with a loss of precision.

Method Summary

java.lang.Float	readObjectData(java.nio.ByteBuffer buffer, java.lang.Class type) Reads an object from the buffer.

Constructor Detail

FloatSerializer

public FloatSerializer()

Creates a FloatSerializer that allows uses 4 bytes to represent a float, with no loss of precision.

FloatSerializer

public FloatSerializer(float precision,
                       boolean optimizePositive)

Creates a FloatSerializer that allows uses 1-5 bytes to represent a float, with a loss of precision. The float is multiplied by the specified precision, then cast to an int and serialized with IntSerializer. IntSerializer uses 1-4 bytes from 0 to 268,435,455 with "optimize positive" and -134,217,728 to 134,217,727 without. If a float multiplied by the precision would fall outside these values, it will take 5 bytes to serialize and it may be better to use the other FloatSerializer constructor.
