Class ObjectState

java.lang.Object

org.graalvm.compiler.virtual.phases.ea.ObjectState

public class ObjectState
extends Object

This class describes the state of a virtual object while iterating over the graph. It describes the fields or array elements (called "entries") and the lock count if the object is still virtual. If the object was materialized, it contains the current materialized value.
