Class Resources

java.lang.Object

com.oracle.svm.core.jdk.Resources

public final class Resources
extends Object

Support for resources on Substrate VM. All resources that need to be available at run time need to be added explicitly during native image generation using Resources.registerResource(java.lang.String, java.io.InputStream). Registered resources are then available from DynamicHub#getResource classes and class loaders.
