Class GsonFeature

java.lang.Object

com.oracle.svm.thirdparty.gson.GsonFeature

All Implemented Interfaces:

org.graalvm.nativeimage.hosted.Feature

public final class GsonFeature
extends Object
implements org.graalvm.nativeimage.hosted.Feature

Support for the Gson library on SubstrateVM.

Gson uses reflection to instantiate data classes and write properties. All such data classes need to be registered manually by the user using the runtime reflection support of Substrate VM. It is not feasible to automatically detect all necessary classes.

This feature registers parts of sun.misc.Unsafe as reflectively accessible. Gson uses it internally to instantiate classes that do not have a no-argument constructor.
