Language interoperability is the capability of two different programming languages to natively interact as part of the same system and operate on the same kind of data structures. [1] There are many ways programming languages are interoperable with one another. HTML, CSS, and JavaScript are interoperable as they are used in tandem in webpages.
Standard mappings exist for Ada, C, C++, C++11, COBOL, Java, Lisp, PL/I, Object Pascal, Python, Ruby, and Smalltalk. Non-standard mappings exist for C#, Erlang, Perl, Tcl, and Visual Basic implemented by object request brokers (ORBs) written for those languages. Versions of IDL have changed significantly with annotations replacing some pragmas.
In JNI, for example, C code which "holds on to" object references that it receives from Java must communicate this information successfully to the Java virtual machine or Java Runtime Environment (JRE), otherwise, Java may delete objects before C finishes with them. (The C code must also explicitly release its link to any such object once C has ...
In software design, the Java Native Interface (JNI) is a foreign function interface programming framework that enables Java code running in a Java virtual machine (JVM) to call and be called by [1] native applications (programs specific to a hardware and operating system platform) and libraries written in other languages such as C, C++ and assembly.
Probably the most commercially important recent object-oriented languages are Java, developed by Sun Microsystems, as well as C# and Visual Basic.NET (VB.NET), both designed for Microsoft's .NET platform. Each of these two frameworks shows, in its way, the benefit of using OOP by creating an abstraction from implementation.
Blittable types are data types in the Microsoft .NET Framework that have an identical presentation in memory for both managed and unmanaged code. Understanding the difference between blittable and non-blittable types can aid in using COM Interop or P/Invoke, two techniques for interoperability in .NET applications.
