Dynamic dispatch vs static dispatch

WebSep 6, 2013 · The idea is that, if the thing you're automating is a dynamic object (like the kind of object you have in Python or Javascript), rather than a static object (like the kind of object you have in C++ or Java), Visual Basic code can access its dynamic nature—enumerate, add, and remove members at runtime, etc. WebAlso dynamic dispatch has more of an OO flavor to it... it's the mechanism behind polymorphism, in which a reference to an object might point to one of multiple implementations. Dynamic dispatch decides at runtime which one to actually run. By contrast, late binding would be dropping in whole new methods that weren't there at …
