Class ClassInitializationFeature

java.lang.Object

com.oracle.svm.hosted.ClassInitializationFeature

All Implemented Interfaces:

org.graalvm.nativeimage.Feature, org.graalvm.nativeimage.impl.RuntimeClassInitializationSupport

public final class ClassInitializationFeature
extends Object
implements org.graalvm.nativeimage.Feature, org.graalvm.nativeimage.impl.RuntimeClassInitializationSupport

This class contains the hosted code to support initialization of select classes at runtime. It handles the registration (implementing the functionality of the RuntimeClassInitialization API) and prepares the ClassInitializationInfo objects that are used at runtime to do the initialization.
