Detailed Description

This class is for testing the input managers.

In this context testing means reading in all the transactions of a transactional database. To select the best transaction reader run testers/input-tester with different parameters, and measure the times, for example by using /usr/bin/time.

The read in transactions are neither stored nor used for anything. A temporal transaction is always overwritten with the new transaction. Also, this class does not check if the transaction reader works properly. If you want to check, compile the program with DEBUG_LEVEL >= LEVEL_DBG (i.e. make input-reader DEBUG_LEVEL=255) and check if the output is the same as the tranasction database. For example:

./testers/input-tester stream simple ../data/T10I4D100K.dat 8000 1 | diff - ../data/T10I4D100K.dat

Note that a transaction reader may change the order of item in a transaction, or in some databases the white space after the last items of all/some transactions are ommited, and hence the output may differ from the transactional database.
