VMHelper
public class VMHelper (Code)
Core class for DRLVM's vmmagic based helpers. Resolved and initilized during VM startup Note: All classes with vmmagic based helpers registred in VM are also resolved and initialized at VM startup Note: If you need to initialize another DRLVM's specific utility class related to vmmagic infrastructure refer to it from static section of this class: and it will also be automatically initialized
