QueryOp* mongo::QueryOp::createChild ( ) [inline]

Returns:: a copy of the inheriting class, which will be run with its own query plan. If multiple plan sets are required for an $or query, the QueryOp of the winning plan from a given set will be cloned to generate QueryOps for the subsequent plan set. This function should only be called after the query op has completed executing.
