Class InMemoryWorkspaceCache.InMemoryCachePolicy

java.lang.Object
  org.modeshape.graph.connector.path.cache.InMemoryWorkspaceCache.InMemoryCachePolicy

All Implemented Interfaces:

Serializable, CachePolicy, PathCachePolicy

Enclosing class:

InMemoryWorkspaceCache

public static class InMemoryWorkspaceCache.InMemoryCachePolicy
extends Object
implements PathCachePolicy

Trivial 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.
