NativeUtil

Provides some methods that are possible in JNI, but not possible in Java (without using Unsafe etc.)

Note

• callTypeMethod and invokeType methods are 30x+ slower than reflection (68.447 ± 30.569 ns/op)
• Method with java.lang.Void parameter type is not supported and will crash the JVM when trying to invoke them
• You need to use BoxedValue class to pass the value of boxed primitive type to method, for example:

  NativeUtil/src/test/java/net/blueberrymc/nativeutil/NativeUtilTest.java

  Lines 40 to 43 in c194dd4

  	Method method2 = YouCannotCreateInstanceOfThisClass.class.getDeclaredMethod("calculate", Integer.class, Integer.class);
  	long method2id = NativeUtil.getMethodId(method2);
  	int i2 = NativeUtil.callInt(method2id, null, new BoxedValue(100000), new BoxedValue(15115));
  	assert i2 == 115115 : i2;
