Class Conversion

edu.internet2.middleware.grouperClientExt.org.apache.commons.lang3.Conversion
public class Conversion extends 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:

  • binary: an array of booleans
  • byte or byteArray
  • int or intArray
  • long or longArray
  • hex: a String containing hexadecimal digits (lowercase in destination)
  • hexDigit: a Char containing a hexadecimal digit (lowercase in destination)
  • uuid

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.
