Dynamic Ranguage Runtime (DLR)
- 2. What’s Dynamic Object Type isn’t known until runtime
- 3. Which Means
- 4. Member names and signatures aren’t known until runtime
- 5. Therefore
- 7. Call can fail dynamically
- 8. That’s too boring to deal with !!
- 10. Dynamic Structures such as XML or HTML DOM
- 12. Dynamic Language A high level language which, at runtime, execute many common programming behaviors that static programming languages perform during compilation
- 13. Dynamic languages such as Python and Ruby
- 14. Introducing a new Keyword in c# Dynamic
- 15. Dynamic is a Type
- 17. Statically declares an object to be dynamic
- 18. Replace compile-time type check with writing metadata about the call
- 19. Use metadata at runtime to resolve the call
- 25. Dynamic != var
- 27. DLR is a normal assembly hosted on the CLR
- 28. Dynamic Language A high level language which, at runtime, execute many common programming behaviors that static programming languages perform during compilation
- 29. CLR & DLR CLR: The CLR is the core set of services offered by .Net - a type system, JIT, a garbage collector. DLR: builds atop of this and offers services for dynamic languages: dynamic types, dynamic method dispatch, code generation
- 30. How is it Helpful • Provides support for dynamic features in statically typed languages. • Facilitates sharing of libraries and objects. • Provides support for dynamic method dispatch and invocation.
- 31. The DLR subsystem • Expression Trees To represent language semantics • Call site caching Method calls using dynamic objects are cached in the memory for faster dispatch. • Dynamic object interoperability The DLR enables interoperability between statically and dynamically typed languages.
- 32. The Dynamic Language Runtime includes a collection of types– classes and interfaces in the System.Dynamic.namespace
- 33. Language Binders The language binders in the DLR help it to talk to other languages. .Net Binder -- this is used to talk to .Net objects JavaScript Binder -- this is used to talk to objects created in JavaScript objects IronRuby Binder -- enables the DLR to talk to IronRuby objects IronPython Binder -- helps the DLR to talk to IronPython objects COM Binder -- this helps the DLR to talk to COM objects
