Computing POM metrics using PADL is made easy by the helper class pom.helper.MetricsGenerator
. After having installed CPL, PADL, and POM, just go into the POM Tests
project and have a look at this class. It provides a main method with snippets of code to call one of the three methods:
computeMetricsFromDirectory
computeMetricsFromEclipse
computeMetricsFromJARs
which can be used to compute automatically metrics from various input sources. Also have a look at the constant array listing the metrics that must be computed or avoided: METRICS_TO_AVOID
and METRICS_TO_COMPUTE
.
