| <div class="block"><h2>Sketching Core Library</h2> |
| <h3>Overview</h3> |
| |
| <p>The Sketching Core Library provides a range of stochastic streaming algorithms and closely |
| related java technologies that are particularly useful when integrating this technology into |
| systems that must deal with massive data. Click on the package links below for the package |
| introduction and APIs. |
| </p> |
| |
| <p>This library is divided into packages that constitute distinct groups of functionality:</p> |
| |
| <ul> |
| <li><b><a href="com/yahoo/sketches/frequencies/package-summary.html">Frequencies</a></b> |
| </li> |
| |
| <li><b><a href="com/yahoo/sketches/hash/package-summary.html">Hash</a></b> |
| </li> |
| |
| <li><b><a href="com/yahoo/sketches/hll/package-summary.html">HLL</a></b> |
| </li> |
| |
| <li><b><a href="com/yahoo/sketches/hllmap/package-summary.html">HLLMap</a></b> |
| </li> |
| |
| <li><b><a href="com/yahoo/sketches/quantiles/package-summary.html">Quantiles</a></b> |
| </li> |
| |
| <li><b><a href="com/yahoo/sketches/sampling/package-summary.html">Sampling</a></b> |
| </li> |
| |
| <li><b><a href="com/yahoo/sketches/theta/package-summary.html">Theta</a></b> |
| </li> |
| |
| <li><b><a href="com/yahoo/sketches/tuple/package-summary.html">Tuple</a></b> |
| </li> |
| </ul> |
| Note: In general, if the requirements or promises of any method's contract are not fulfilled |
| (that is, if there is a bug in either the method or its caller), |
| then an unchecked exception will be thrown. |
| The precise type of such an unchecked exception does not form part of any method's contract.</div> |
