Examples of TreeCache

Tree cache interface. A tree cache holds expression trees by expression strings. A tree cache implementation must be thread-safe. @author Christoph Beck
org.apache.curator.framework.recipes.cache.TreeCache

A utility that attempts to keep all data from all children of a ZK path locally cached. This class will watch the ZK path, respond to update/create/delete events, pull down the data, etc. You can register a listener that will get notified when changes occur.

IMPORTANT - it's not possible to stay transactionally in sync. Users of this class must be prepared for false-positives and false-negatives. Additionally, always use the version number when updating data to avoid overwriting another process' change.
