Class JNIJavaCallWrapperMethod

java.lang.Object

com.oracle.svm.jni.hosted.JNIJavaCallWrapperMethod

All Implemented Interfaces:

com.oracle.graal.pointsto.infrastructure.GraphProvider, AnnotatedElement, jdk.vm.ci.meta.InvokeTarget, jdk.vm.ci.meta.JavaMethod, jdk.vm.ci.meta.ModifiersProvider, jdk.vm.ci.meta.ResolvedJavaMethod

public final class JNIJavaCallWrapperMethod
extends Object

Generated code for calling a specific Java method from native code. The wrapper takes care of transitioning to a Java context and back to native code, for catching and retaining unhandled exceptions, and if required, for unboxing object handle arguments and boxing an object return value.
