      Parameters:
      theClass - class to test

    • objectIsPrimitiveArray

      public static boolean objectIsPrimitiveArray(Object o)
      Test whether an Object is an array of primitive types
      Parameters:
      o - object to test

    • classnameIsArray

      public static boolean classnameIsArray(String classname)
      Test whether a classname is an array
      Parameters:
      classname - classname string

    • classnameIsPrimitiveArray

      public static boolean classnameIsPrimitiveArray(String classname)
      Test whether a classname is a primitive array
      Parameters:
      classname - classname string

    • getPrimitiveArrayTypeCode

      public static char getPrimitiveArrayTypeCode(Class theClass)
      Return the primitive element type code for an array of primitive types. Same as getPrimitiveArrayTypeCode( theClass.getName() )
      Parameters:
      classname - the Class object

    • getPrimitiveArrayTypeCode

      public static char getPrimitiveArrayTypeCode(String classname)
      Return the primitive element type code for an array of primitive types.
      Parameters:
      classname - classname string

    • getArrayMemberClassName

      public static String getArrayMemberClassName(String classname)
      Get the classname for an array element.
      Parameters:
      classname - classname string

    • getClassFromName

      public static Class getClassFromName(String classname) throws ClassNotFoundException

    • isPrimitiveClass

      public static boolean isPrimitiveClass(Class theClass)
      Test whether a class is a primitive class.
      Parameters:
      theClass - the class to test
