Class ByteArrayClassPath

  • All Implemented Interfaces:

    public class ByteArrayClassPath
    extends java.lang.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.
