Conversions

final public class Conversions (Code)

This class encapsulates methods to deal with arrays of numbers, converting from numbers to bytes and bytes to numbers.

Methods xxxToByte() convert a Java array of primitive numbers (int, short, ...) to a Java array of bytes. Methods byteToXxx() convert from a Java array of bytes into a Java array of primitive numbers (int, short, ...)

Variant interfaces convert a section of an array, and also can convert to sub-classes of Java Number.
