Set Action Subsystem

mint.sm-meta.action.td.16 / Leon Starr / Version 0.1.0

The union, intersection, and difference set operations may be performed on Instance Flows similarly to the way they are handled in the Relational Action Subsystem.

Let's say you have one Instance Flow with references to Aircraft N1338Q and N1942B and another input Instance Flow with references to N9924L and N1138Q. If you flow them both into the UNION set action, an output Instance Flow will carry references to N1338Q, N1942B, and N9924L.

Whereas the correpsonding Relation Actions take Non Scalar Input Flows as input and output a Relation Flow, the Instance Set Actions take Instance Flow operands only yielding an Instance Flow output. Both inputs must be typed as the same Class with the resulting output also having the same Class type.
