Enum Class CRIUSupport.HookMode

java.lang.Object

java.lang.Enum<CRIUSupport.HookMode>

org.eclipse.openj9.criu.CRIUSupport.HookMode

All Implemented Interfaces:

Serializable, Comparable<CRIUSupport.HookMode>, Constable

Enclosing class:

CRIUSupport

public static enum CRIUSupport.HookMode
extends Enum<CRIUSupport.HookMode>

A hook can be one of the following states: SINGLE_THREAD_MODE - a mode in which only the Java thread that requested a checkpoint is permitted to run. This means that global state changes are permitted without the risk of race conditions. It also implies that if one attempts to acquire a resource held by another Java thread a deadlock might occur, or a JVMCheckpointException or JVMRestoreException to be thrown if such an attempt is detected by JVM. CONCURRENT_MODE - a hook running when the SINGLE_THREAD_MODE is NOT enabled
