Detailed Description

template<Is_set Source_tp>
class mysql::sets::Optional_view_source_set< Source_tp >

Used to represent an optional source of a view, when that source is a set.

Provides the functions find, lower_bound, and upper_bound which work even if the optional source is absent, in which case they return the end iterator.
