    • toJvmName

      public static String toJvmName(String javaname)
      Generate the internal binary name (jvm name) for the provided type name, as provided by Class.getName().

      Class.getName() uses inconsistent format. Example: 

       int                      -> int
 int[]                    -> [I
 int[][]                  -> [[I
 java.lang.Integer        -> java.lang.Integer
 java.lang.Integer[]      -> [Ljava.lang.Integer;
 java.lang.Integer[][]    -> [Ljava.lang.Integer;
      Parameters:
      javaname - name returned by Java's Class.getName(...)
      Returns:

    • toJvmName

      public static String toJvmName(Class<?> c)
