public class FloatArrayCodec extends AbstractPrimitiveArrayCodec<float[]>
list<float> to the Java type float[].
Note that this codec is designed for performance and converts CQL lists directly to
float[], thus avoiding any unnecessary boxing and unboxing of Java primitive float values; it also instantiates arrays without the need for an intermediary Java List
object.
