Class InMemoryNodeCache.MapCachePolicy<NodeType extends MapNode>

java.lang.Object
  org.modeshape.graph.connector.base.cache.InMemoryNodeCache.MapCachePolicy<NodeType>

Type Parameters:

NodeType - the node type that is being cached

All Implemented Interfaces:

Serializable, CachePolicy, NodeCachePolicy<UUID,NodeType>

Enclosing class:

InMemoryNodeCache<KeyType,NodeType extends Node>

public static class InMemoryNodeCache.MapCachePolicy<NodeType extends MapNode>
extends Object
implements NodeCachePolicy<UUID,NodeType>

Path cache policy implementation that caches all nodes in an in-memory cache.

As a result, this cache policy may not be safe for use with some large repositories as it does not attempt to limit cache attempts based on the size of the node or the current size of the cache.
