registerNatives

Registers native methods with the class specified by the receiver. The methods parameter specifies a list of triples that contain the names, signatures and function pointers of the native methods.

The function pointers nominally must have the following signature:

(env: JniEnv, objectOrClass: JObject, ...) -> JBoolean|Byte|JChar|Short|Int|Long|Float|Double|JObject|Unit

Be aware that registerNatives can change the documented behavior of the JVM (including cryptographic algorithms, correctness, security, type safety), by changing the native code to be executed for a given native Java method. Therefore, use applications that have native libraries utilizing the registerNatives function with caution.

Throws

Registers native methods with the class specified by the clazz argument.

The function pointers nominally must have the following signature:

(env: JniEnv, objectOrClass: JObject, ...) -> JBoolean|Byte|JChar|Short|Int|Long|Float|Double|JObject|Unit

Example:

clazz.registerNatives(1) {
    register("myGetStringBytes".utf8, "(Ljava/lang/String;II[B)V".utf8, staticCFunction { env: JniEnv, obj: JObject, jstr: JString, offset: Int, len: Int, buf: JByteArray ->
        ...
    })
}
