public interface JConstant
extends JClassFileItem

An object of the JConstant interface represents a constant pool entry. (@see #fr.umlv.corosol.classfile.constant.JConstantPool).

A constant pool entry can takes up two entries (e.g. the Constant_Double and Constant_Long entries). Then, the getLength method returns the number of entries occupied by an entry in the constant pool.
