org.apache.derby.impl.sql.execute.AggregatorInfo
This is a simple class used to store the run time information needed to invoke an aggregator. This class is serializable because it is stored with the plan. It is serializable rather than externalizable because it isn't particularly complicated and presumbably we don't need version control on plans. @author jamie
