Package orc.trace Description

Generate and query Orc trace files. An Orc trace file is a gziped sequence of serialized Event Handles. These trace files are written with OutputStreamTracer and read with InputStreamEventCursor. It's possible to define other kinds of tracers and trace formats by providing your own implementation of TokenTracer.
