//entries.  It delegates responsibility for actually building the
//indvidual parameter entries to helper classes (DtTankParametersBuilder,
//DtWaypointParametersBuilder, etc.).  Parameters object returned by
//this class should be fully constructed and configured (all of their
//resources, components, parameter settings appropriate to the particular
//type of object are specified).
