| <h2>Overview</h2> |
| |
| <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> |

| 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> |
