Element Detail

jniConfig

public abstract Class<?> jniConfig

The native bridge configuration. The returned class must have an accessible static getInstance() method returning a JNIConfig instance. The returned JNIConfig instance is used for marshallers' lookup.

include

public abstract Class<? extends BooleanSupplier> include

If the supplier returns true, the bridge entry points are added automatically when building a shared library. This means the bridge entry points are root methods for compilation, and everything reachable from them is compiled too. The provided class must have a nullary constructor, which is used to instantiate the class. The BooleanSupplier.getAsBoolean()} function is called on the newly instantiated instance.

Default:

org.graalvm.nativeimage.c.function.CEntryPoint.AlwaysIncluded.class
