Class ExtendedObjectMetadata

java.lang.Object

com.scaleoutsoftware.soss.client.ObjectMetadata

com.scaleoutsoftware.soss.client.ExtendedObjectMetadata

All Implemented Interfaces:

java.io.Serializable

public class ExtendedObjectMetadata
extends ObjectMetadata

ExtendedObjectMetadata augments the user-specified ObjectMetadata values with additional read-only values maintained automatically by the StateServer. Instances of ExtendedObjectMetadata are returned by NamedCache.getMetadata(com.scaleoutsoftware.soss.client.CachedObjectId, com.scaleoutsoftware.soss.client.ReadOptions).

Method Summary

Modifier and Type	Method and Description
long	createTime() Returns the create time of the object.
boolean	getAbsoluteTimeout() Returns true if the StateServer object corresponding to this metadata instance will be removed from the store at a specific absolute time as opposed to a sliding expiration timeout due to a period of inactivity.
boolean	getAllowRemoteAccess() Returns true if the object can be accessed by the remote store, false otherwise.
boolean	getAllowReplication() Returns true if the StateServer object corresponding to this metadata instance can be replicated to remote stores.
BackingStoreAsyncPolicy	getBackingStoreAsyncPolicy() Returns the type of backing store operations (none, refresh-ahead or write-behind) performed on the StateServer object corresponding to this metadata instance.
TimeSpan	getBackingStoreInterval() Gets the interval between asynchronous backing store events (refresh-ahead, write-behind) for the StateServer object corresponding to this metadata instance.
CoherencyPolicy	getDefaultCoherencyPolicy() Gets the default coherency policy or null if no coherency policy is set.
IndexCollection	getIndexCollection() Gets the IndexCollection
int	getObjectSize() Returns the size in bytes of the StateServer object corresponding to this metadata
java.util.Set<CachedObjectId>	getParents() Return a read-only list containing the dependency parents specified for the StateServer object corresponding to this ObjectMetadata instance.
ObjectPreemptionPriority	getPreemptionPriority() Returns the preemption priority of the StateServer object corresponding to this metadata instance.
TimeSpan	getTimeout() Returns the expiration timeout value for the StateServer object corresponding to this metadata.
boolean	isProxy() Checks if the object is a proxy object for "pull" replication.
long	updateTime() Returns the update time of the object.
