Detailed Description

Base class for meta-iterators.

This base class shares code for concurrent and hybrid meta-iterators, where the former supports multi-start and Pareto set iteration and the latter supports sequential, embedded, and collaborative hybrids.

Member Function Documentation

void post_run

(

std::ostream &

s

)

[protected, virtual]

post-run portion of run (optional); verbose to print results; re-implemented by Iterators that can read all Variables/Responses and perform final analysis phase in a standalone way

Post-run phase, which a derived iterator may optionally reimplement; when not present, post-run is likely integrated into run. This is a virtual function; when re-implementing, a derived class must call its nearest parent's post_run(), typically _after_ performing its own implementation steps.

Reimplemented from Iterator.
