org.dataone.client.NodeLocator

org.dataone.client.v1.impl.NodeListNodeLocator

org.dataone.client.v1.impl.SettingsContextNodeLocator

public class SettingsContextNodeLocator
extends NodeListNodeLocator

This implementation of NodeLocator uses property defined in the configuration to determine the NodeList to use for the mapping NodeReferences to baseUrls. As with NodeListNodeLocator, these should be relied on instead of using the put methods. The MNode and CNode objects are instantiated the first time they are requested from the get methods. Use of the put methods will replace the current D1Node associated with the NodeReference, so should be used with care. While most applications require / desire to have only one instance of a NodeLocator, with Singleton or Monostate behavior, this class does not do that, to support applications that work across environments. See org.dataone.client.itk.D1Client for this.
