# ABSTRACT: Used by CxnPools to create new Cxn instances.

=head1 DESCRIPTION

This class is used by the L<Search::Elasticsearch::Role::CxnPool> implementations
to create new L<Search::Elasticsearch::Role::Cxn>-based instances. It holds on
to all the configuration options passed to L<Elasticsearch/new()> so
that new Cxns can use them.

It contains no user serviceable parts.
