- *
- * <B>Note:</B> This class returns and accepts types as Classes, even
- * primitive types; there are Class types defined that represent each
- * different primitive type. They are <code>java.lang.Boolean.TYPE,

- * The Method class represents a member method of a class. It also allows
- * dynamic invocation, via reflection. This works for both static and
- * instance methods. Invocation on Method objects knows how to do
- * widening conversions, but throws {@link IllegalArgumentException} if
- * a narrowing conversion would be necessary. You can query for information
- * on this Method regardless of location, but invocation access may be limited
- * by Java language access controls. If you can't do it in the compiler, you
- * can't normally do it here either.<p>
- *
- * <B>Note:</B> This class returns and accepts types as Classes, even
- * primitive types; there are Class types defined that represent each
- * different primitive type. They are <code>java.lang.Boolean.TYPE,
- * java.lang.Byte.TYPE,</code>, also available as <code>boolean.class,
- * byte.class</code>, etc. These are not to be confused with the
- * classes <code>java.lang.Boolean, java.lang.Byte</code>, etc., which are
- * real classes.<p>
- *
- * Also note that this is not a serializable class. It is entirely feasible
- * to make it serializable using the Externalizable interface, but this is
- * on Sun, not me.
