All Implemented Interfaces:

LIRLowerable, Cloneable, Formattable, KindProvider

public final class DirectReadNode
extends FixedWithNextNode
implements LIRLowerable

A special purpose store node that differs from UnsafeStoreNode in that it is not a StateSplit and takes a computed address instead of an object.
