Constructor Detail

ClusterAccess

public ClusterAccess()

Constructs a new parameter cluster dump instance. The command line switches understood are registered here.

Method Detail

process

public boolean process(String[] arg)
                throws ParseException

Processes the command line arguments. After parsing, there must be a single reference to the binding name of an RmiParameterClustering instance (i.e. a single unmatched command parameter). This name is resolved into a reference to the parameter cluster to query. The both command-line switches understood either dump the entire set of parameter names to System.out (switch '-d') or query the value of a single parameter (switch '-q').

Returns:

True, if the request could be fulfilled.

Throws:

ParseException

main

public static void main(String[] arg)
                 throws ParseException

Performs a look-up operation on the binding name stated on the command line. If there is a valid binding and it binds a RmiParameterClustering instance either a single value is queried or the names of all parameters hosted are dumped to the command line.

Throws:

ParseException
