Overview

Analysers are used to analyse the current state of the evolution at given stages. These objects may be used to gather data, calculate statistics and log information during the evolution.

Analysers may harness the outputs of attached analysers to supplement their input data. This ability can be exploited to perform multi-stage post-processing and to efficiently record information.

Instance Method Details

#run(stage, state) ⇒ Object

Runs this analyser at a given stage in the evolution.

Executes the input analysers to gather the input data which is then fed into the appropriate stage handler of this analyser.
