Enabling two or more disparate entities to work together.Why interoperability? No language or platform is good for everything. Fast inner loop Makes UX easy Has tooling for workload High performance Simplified Wrapper and Interface Generator (SWIG) – 1996 JVM – Java Native Interface (JNI) – 1997 .NET – Platform Invoke (P/Invoke), COM interop, C++/CLI – 2002, 2005 JVM – Java Native Access (JNA) – 2007 Go – scenarios with a Garbage Collector (GC). 1. Handles – Level of indirection. • Usually requires a “platform” API to use the memory. • .NET has GCHandle. • JVM, through JNI, exposes most memory as a handle
