Class: RuboCop::Cop::Metrics::PerceivedComplexity
- Includes:
- IfNode, RuboCop::Cop::MethodComplexity
- Defined in:
- lib/rubocop/cop/metrics/perceived_complexity.rb
Overview
This cop tries to produce a complexity score that's a measure of the
complexity the reader experiences when looking at a method. For that
reason it considers when
nodes as something that doesn't add as much
complexity as an if
or a &&
. Except if it's one of those special
case
/when
constructs where there's no expression after case
. Then
the cop treats it as an if
/elsif
/elsif
... and lets all the when
nodes count. In contrast to the CyclomaticComplexity cop, this cop
considers else
nodes as adding complexity.
