Annotation Type EnableExpiration.ExpirationPolicy

public static @interface EnableExpiration.ExpirationPolicy

Definition for a specific Expiration policy that can be applied to 1 or more Regions. An Expiration policy defines the expiration timeout and expiration action to take when an Region entry times out. Additionally, the Expiration policy defines the algorithm to use (e.g. Idle Timeout (TTI) or Time-To-Live (TTL), or both) to determine if and when an Region entry has timed out.

Element Detail

timeout

public abstract int timeout

Specifies the timeout used to determine when a Region entry expires. This value of this attribute determines the "default" timeout used if no specific timeout was specified. A specific timeout is determined by Expiration.timeout(), IdleTimeoutExpiration.timeout() or TimeToLiveExpiration.timeout() attribute on the application domain object.

action

public abstract ExpirationActionType action

Specifies the action taken when a Region entry expires. This value of this attribute determines the "default" action taken if no specific action was specified. The specific action is determined by Expiration.action(), IdleTimeoutExpiration.action() or TimeToLiveExpiration.action() attribute on the application domain object.
