The title of the speech is “Dynamic C++”; here is the description:<\/p>\n

The C++ static type system is beneficial in many ways; it can, however, also be a straitjacket. Is there a rationale for dynamic type layer on top of a statically typed language like C++? Given both historical (ANSI C union and void*, Microsoft<\/a> COM Variant<\/a>, boost::[variant<\/a>, any<\/a>, lexical_cast<\/a>]) and recent (boost::type_erasure<\/a>, Facebook<\/a> folly::dynamic<\/a>) development trends, the answer is a resounding “yes”.<\/p>\n

This presentation is based on Poco::Dynamic::Var (aka Poco::DynamicAny) – a dynamic-typing set of C++ classes; furthermore, it will show the simplicity and practical advantages of mapping ad-hoc generated data sets of unknown type, size, and structure to C++ data structures. Specifically, the presentation demonstrates how to:<\/p>\n

    \n
  1. Execute a generic “SELECT * FROM Table”;<\/li>\n
  2. Dynamically map returned data (row\/column count and types) to C++ data structures at runtime;<\/li>\n
  3. Format the result as [XML, JSON, HTML, your-favorite-data-format-here];<\/li>\n
  4. Stream the resulting formatted string to std::ostream compliant HTTP socket stream.<\/li>\n<\/ol>\n

    Surely, this must be very complicated to do in C++, right? Not at all – we’ll demonstrate all of the above done with a single line of code<\/em> and then peek under the hood to see where\/how does the magic happen. Portable? Of course. Scalable? You bet – it’s C++! The content of this presentation fits perfectly into modern AJAXian trends and we’ll prove it with an ExtJS<\/a> example; it prompts re-thinking of the rationale for (a) employing dynamic languages on the server side or (b) polluting HTML with server-side code.<\/p>\n<\/blockquote>\n

    If you are in the neighborhood or interested enough to travel, register online (it’s free) and stop by<\/a> for some good time and interesting presentations\/discussions. Also, if interested in my speech, indicate it on the Code Camp website<\/a> so I can gauge what audience size to expect. See you there!<\/p>\n","protected":false},"excerpt":{"rendered":"
