Class DataCacheConnector

java.lang.Object

  +--netcharts.server.api.DataCacheConnector

public class DataCacheConnector

extends java.lang.Object

This class provides true local (single-JVM) and embedded server access to the data cache (note that remote data cache access is provided within NSWebToolkit). This shields toolkit classes from directly invoking the DataCache, which can cause problems in embedded mode when it is not in the client application classpath.
