public class Conversion
extends java.lang.Object
Static methods to convert a type into another, with endianness and bit ordering awareness.
The methods names follow a naming rule:
<source type>[source endianness][source bit ordering]To<destination type>[destination endianness][destination bit ordering]
Source/destination type fields is one of the following:
Endianness field: little endian is the default, in this case the field is absent. In case of
big endian, the field is "Be".
Bit ordering: Lsb0 is the default, in this case the field
is absent. In case of Msb0, the field is "Msb0".
Example: intBeMsb0ToHex convert an int with big endian byte order and Msb0 bit order into its hexadecimal string representation
Most of the methods provide only default encoding for destination, this limits the number of ways to do one thing. Unless you are dealing with data from/to outside of the JVM platform, you should not need to use "Be" and "Msb0" methods.
Development status: work on going, only a part of the little endian, Lsb0 methods implemented so far.
