+/**
+ * A <code>ByteArrayClassPath</code> contains bytes that is served as
+ * a class file to a <code>ClassPool</code>.  It is useful to convert
+ * a byte array to a <code>CtClass</code> object.
+ *
+ * <p>For example, if you want to convert a byte array <code>b</code>
+ * into a <code>CtClass</code> object representing the class with a name
+ * <code>classname</code>, then do as following:
+ *
+ * <ul><pre>
+ * ClassPool cp = ClassPool.getDefault();
+ * cp.insertClassPath(new ByteArrayClassPath(classname, b));
+ * CtClass cc = cp.get(classname);
+ * </pre></ul>
+ *
+ * <p>The <code>ClassPool</code> object <code>cp</code> uses the created
+ * <code>ByteArrayClassPath</code> object as the source of the class file.
+ * 
+ * <p>A <code>ByteArrayClassPath</code> must be instantiated for every
+ * class.  It contains only a single class file.
