Class ParameterMapExtractor

java.lang.Object
  org.glassfish.common.util.admin.ParameterMapExtractor

public class ParameterMapExtractor
extends java.lang.Object

Extracts a ParameterMap corresponding to the parameters defined on injected objects, such as AdminCommand or CommandParameters implementations.

This can be useful from a supplemental command which needs to create a new command invocation, with parameters similar to its own, for execution on a cluster.
