Class ShimConfig

java.lang.Object
  com.novell.nds.dirxml.shimhost.ShimConfig

All Implemented Interfaces:

ConfigElement, ShimHost.DriverPasswordCheck, ShimHost.StateListener, ShimParams.ReferenceResolver

public class ShimConfig

extends Object

implements ShimParams.ReferenceResolver, ShimHost.StateListener, ShimHost.DriverPasswordCheck, ConfigElement

Class encapsulating the DirXML shim configuration information necessary for running a shim.

The primary use of this class is the construction of initialization documents for the shim init() methods. However, it may also be useful as the back end for a configuration editor.

The ShimConfig class is designed to read and write all the configuration data from a single XML document. However, ShimConfig can also be used as an aggregator for configuration data from multiple sources. In either case, a ShimConfig instance can be used to construct XML documents to be used as parameters to shim init() methods.
