Detailed Description

template<class TR = brBufferedTransactionReader< >>
class StatInput< TR >

An input manager class that collects some statistics (number of transactions, number of items, average size of the transactions) about the transation database.

This class is a wrapper around a transaction_reader. Collecting statistics needs resources thus do not use this class unless you are not interesred in performance.
