§ intersect()

virtual std::unique_ptr<ArbiterRequirement> ArbiterRequirement::intersect ( const ArbiterRequirement & rhs ) const

pure virtual

Attempts to create a requirement which expresses the intersection of this requirement and the given one.

In other words, this attempts to find the loosest possible requirement which is a superset of the two inputs. Any version which passes the intersected requirement would also pass either one of the original inputs.

Returns nullptr if no intersection is possible.
