ppamltracer is a lightweight, portable tracing library designed for * explicit instrumention of generated code. If you're writing a compiler and * need hard data on your optimizer's efficacy, ppamltracer is the library for * you. This Java package provides bindings to the libppamltracer C API. * *

This package's usage can be summed up in a few lines: * *

 *   // Create report.
 *   Tracer tracer = new ExplicitlyConfiguredTracer("/tmp/my_report");
 *
 *   // Register phase 1 and do stuff.
 *   Phase phase = tracer.createPhase("phase 1");
 *   phase.start();
 *   doStuff();
 *   phase.stop();
 *   phase.close();
 *
 *   // Register phase 2 and do different stuff.
 *   phase = tracer.createPhase("phase 2");
 *   // Other stuff
 *   phase.start();
 *   doOtherStuff();
 *   phase.stop();
 *   // Yet more stuff
 *   phase.start();
 *   doYetMoreStuff();
 *   phase.stop();
 *
 *   // Clean up.
 *   phase.close();
 *   tracer.close();
 * 
* *

This creates a report with the total runtime of doStuff * recorded as "phase 1" and the total runtime of doOtherStuff and * doYetMoreStuff combined as "phase 2". * *

com.galois.ppaml.tracer.examples.Simple, included in the * distribution, contains a more lengthy example. * *

ppamltracer writes trace logs in the * Open Trace Format, a free and * open standard developed by the Zentrum für Informationsdienste und * Hochleistungsrechnen (Center for Information Services and High-Performance * Computing) at the Technical University of Dresden. * *

We developed ppamltracer as part of DARPA's * Probabilistic * Programming for Advancing Machine Learning (PPAML) project. * * @author Galois, Inc. * * @version 0.2.1 */ package com.galois.ppaml.tracer;
