Class ByteArrayClassPath

java.lang.Object
javassist.ByteArrayClassPath
All Implemented Interfaces:
ClassPath
public class ByteArrayClassPath extends Object implements ClassPath
A ByteArrayClassPath contains bytes that is served as a class file to a ClassPool. It is useful to convert a byte array to a CtClass object.

For example, if you want to convert a byte array b into a CtClass object representing the class with a name classname, then do as following: 

 ClassPool cp = ClassPool.getDefault();
 cp.insertClassPath(new ByteArrayClassPath(classname, b));
 CtClass cc = cp.get(classname);

The ClassPool object cp uses the created ByteArrayClassPath object as the source of the class file.

A ByteArrayClassPath must be instantiated for every class. It contains only a single class file.
