Public static (Shared in Visual Basic) members of this type are
safe for multithreaded operations. Instance members are not guaranteed to be
thread-safe.
Remarks
Programmers do not know, nor do they need to know, the names of the actual classes that implement the various link interfaces. They never call a constructor to create a link class. Instead, so-called "factory" methods are provided by the MathLinkFactory class to create the actual objects used.
