61 * copies snapshot of reader's fifo buffer into its own buffer
63 * sets snapshot.begin() and .end() iterators to boundaries of valid entries
73 * calls dump(int, size_t, Snapshot)
74 * NBLog::Reader::dump(int, size, snapshot)
75 * iterates through snapshot's events and switches based on their type
