public class cp_info
extends ClassConstants
cp_info is a class that represents a constant pool entry from a java class file. This class also has the ability to read its entry from a class file and write its entry to a class file.

The information used to write this class was obtained from the book "The Java Virtual Machine Specification", pages 84 - 118.

Note: The use of all lower-case variable names with underscores is done to show an exact translation from the Virtual Machine Specification.
