public class DefaultVariableResolver
extends java.util.HashMap
implements VariableResolver

The DefaultVariableResolver is a HashMap based default implementation of the VariableResolver interface. It may be used by plugins to implement the interface for the request and is also used by the WebConsoleUtil.getVariableResolver(javax.servlet.ServletRequest) as the variable resolver if none has yet been assigned to the request.
