[commons-numbers] 02/03: Added examples module with a JMH examples
module.
Posted by ah...@apache.org.
This is an automated email from the ASF dual-hosted git repository.
aherbert pushed a commit to branch master
in repository https://gitbox.apache.org/repos/asf/commons-numbers.git
commit 4b8103f80d77d6af7a085478ebf4b5fed0376bbd
Author: Alex Herbert <ah...@apache.org>
AuthorDate: Mon Jan 13 16:03:28 2020 +0000
Added examples module with a JMH examples module.
The JMH module contains a benchmark for all operations in Complex.
The examples are currently not included in the standard build. Travis
has been configured to compile them and apply apache-rat:check and
checkstyle:check to maintain the code consistency.

+
+Examples of use of the "Commons Numbers" library.
+ Codes in this module and its sub-modules are not part of the library.
+ They provide checking, benchmarking tools to enhance the documentation

+
+Documentation
+-------------
+
+More information can be found on the [Apache Commons Numbers homepage](https://commons.apache.org/proper/commons-numbers).
+Questions related to the usage of Apache Commons Numbers should be posted to the [user mailing list][ml].
+
+Where can I get the latest release?
+-----------------------------------
+You can download source and binaries from our [download page](https://commons.apache.org/proper/commons-numbers/download_numbers.cgi).
+
+Contributing
+------------
+
+We accept Pull Requests via GitHub. The [developer mailing list][ml] is the main channel of communication for contributors.
+There are some guidelines which will make applying PRs easier for us:
++ No tabs! Please use spaces for indentation.
++ Respect the code style.
++ Create minimal diffs - disable on save actions like reformat source code or organize imports. If you feel the source code should be reformatted create a separate PR for this change.
++ Provide JUnit tests for your changes and make sure your changes don't break any existing tests by running ```mvn clean test```.
+
+If you plan to contribute on a regular basis, please consider filing a [contributor license agreement](https://www.apache.org/licenses/#clas).

+Apache Commons Numbers JMH Benchmark
+===================
+
+Code for running JMH benchmarks that assess performance.
+ Code in this module is not part of the public API.
+
+Documentation
+-------------
+
+More information can be found on the [Apache Commons Numbers homepage](https://commons.apache.org/proper/commons-numbers).
+Questions related to the usage of Apache Commons Numbers should be posted to the [user mailing list][ml].
+
+Where can I get the latest release?
+-----------------------------------
+You can download source and binaries from our [download page](https://commons.apache.org/proper/commons-numbers/download_numbers.cgi).
+
+Contributing
+------------
+
+We accept Pull Requests via GitHub. The [developer mailing list][ml] is the main channel of communication for contributors.
+There are some guidelines which will make applying PRs easier for us:
++ No tabs! Please use spaces for indentation.
++ Respect the code style.
++ Create minimal diffs - disable on save actions like reformat source code or organize imports. If you feel the source code should be reformatted create a separate PR for this change.
++ Provide JUnit tests for your changes and make sure your changes don't break any existing tests by running ```mvn clean test```.
+
+If you plan to contribute on a regular basis, please consider filing a [contributor license agreement](https://www.apache.org/licenses/#clas).
+You can learn more about contributing via GitHub in our [contribution guidelines](CONTRIBUTING.md).
