Detailed Description

concrete implementation of IEvtSelector for ByteStream

An event selector service that steps through Event Filter packed raw events by use of an event source object and an iterator object called EventIteratorByteStream. The type of event source is specified at run time. It

can be a single file, a set of files or the network.
