  - ### Method Detail

    - #### getWrapperClass

          protected static Class<?> getWrapperClass​(Class<?> c)

      Get wrapper class for a given class. If the class is for a primitive number type, then the wrapper class will be returned. If it is no primitive number type, we return the class itself.

    - #### argumentClassIsParameterClass

          protected static boolean argumentClassIsParameterClass​(Class<?> argumentClass,
                                                                 Class<?> parameterClass)

      Realizes an unsharp equal for the class. In general we return true if the provided arguments are the same. But we will also return true if our argument class is a wrapper for the parameter class. For example the parameter is an int and the argument class is a wrapper.

    - #### replaceWithMoreSpecificType

          protected static MethodType replaceWithMoreSpecificType​(Object[] args,
                                                                  MethodType callSiteType)

      Replaces the types in the callSiteType parameter if more specific types given through the arguments. This is in general the case, unless the argument is null.

    - #### isIntCategory

          protected static boolean isIntCategory​(Class<?> x)

    - #### isLongCategory

          protected static boolean isLongCategory​(Class<?> x)

    - #### isBigDecCategory

          protected static boolean isBigDecCategory​(Class<?> x)

    - #### isDoubleCategory

          protected static boolean isDoubleCategory​(Class<?> x)
