Intro

Knee is a Kotlin compiler plugin and companion runtime tools that provides seamless communication between Kotlin/Native binaries and Kotlin/JVM, using a thin and efficient layer around the JNI interface.

With Knee, you can write idiomatic Kotlin/Native code, annotate it and then invoke it transparently from JVM as if they were running on the same environment.

For a brief overview of Knee's capabilities and to see sample code, we recommend checking the features page where you'll learn about all supported features such as:

• Ability to call functions, get or set properties across JNI
• Suspend functions with two-way cancellation, holding structured concurrency together
• Exception support, including custom exception types
• Built-in serialization of language primitives: numbers, strings, nullables, Unit, Nothing
• Built-in serialization of collection types: lists, sets, efficient arrays
• Serialization of enums, classes and objects
• Serialization of interfaces for two-way invocations
• Lambdas and generics support
• No-copy buffers, mapping java.nio buffers to CPointer on native
