Package org.infinispan.container.entries

Class RemoteMetadata

java.lang.Object

org.infinispan.container.entries.RemoteMetadata

All Implemented Interfaces:

InternalMetadata, Metadata

public class RemoteMetadata
extends Object
implements InternalMetadata

This is a metadata type used by scattered cache during state transfer. The address points to node which has last known version of given entry: During key transfer RemoteMetadata is created and overwritten if another response with higher version comes. During value transfer the address is already final and we request the value + metadata only from this node.
