Make

@SharedPtr
public static Comparator Make(Type.type physical_type,
                                          SortOrder.type sort_order,
                                          int type_length)

\brief Create a comparator explicitly from physical type and sort order

Parameters:

physical_type - [in] the physical type for the typed comparator

sort_order - [in] either SortOrder::SIGNED or SortOrder::UNSIGNED

type_length - [in] for FIXED_LEN_BYTE_ARRAY only
