sonar plugin : how to get sonar's metric

Question

I'm working on a Sonar project and I have to make a plugin in order to get metrics and to compute them.

In order to understand how it works, I'd like to try to do the following examples:

• Get the value (complexity) and to compute it as a double or a float value.
• Take the complexity value (MetricsCore.COMPLEXITY) and if it's more than 200, write a message to say that it's too complex.
• Take the number of comments lines and multiply it by 10.

I know that in these examples what I want to do is useless, but it's just to understand how to get the Metrics Core value and take their value, and to create new Metrics. I don't find a lot of documentation....

Thank you very much

For information, I will use Sonar-reference-plugin.

You can find our sample plugins here: https://github.com/SonarSource/sonar-examples/tree/master/plugins. "sonar-reference-plugin" should give you lots of information.

This should help you to better understand how things work.
