Fields

Modifier and Type	Field and Description
static Scope	DISTRIBUTED_ACK The region or cached object with this attribute is scoped to the distributed cached system; any distributed operation will not return until all the remote acknowledgments come back.
static Scope	DISTRIBUTED_NO_ACK The region or cached object with this attribute is scoped to the distributed cached system; any distributed operation will return without waiting for the remote acknowledgment.
static Scope	GLOBAL The region or cached object with this attribute is scoped to the distributed cached system; locking is used for all distributed operations on entries to guarantee consistency across the distributed caches.
static Scope	LOCAL The region with this attribute is scoped to this JVM only.
int	ordinal

Method Summary

Modifier and Type	Method and Description
static Scope	fromOrdinal(int ordinal) Return the Scope represented by specified ordinal
static Scope	fromString(String scope) Parse the given string into a Scope

The region or cached object with this attribute is scoped to the distributed cached system; any distributed operation will not return until all the remote acknowledgments come back.

GLOBAL

@Immutable
public static final Scope GLOBAL

The region or cached object with this attribute is scoped to the distributed cached system; locking is used for all distributed operations on entries to guarantee consistency across the distributed caches.
