Detailed Description

The TransactionConsumer wrapps the logging into a transaction.

From a begin of a logging transaction all log records will be kept in the memory. If the transaction will be commited all records of the transaction will be discarged. If the the transaction will be roll back all log records of the transaction will be written to the underlying consumer. The TransactionConsumer is usefull not to waste the log files with superflous information, but in case of an error situation give supporters full trace information about the situation.
