tuple_intersectiontuple_intersectionTupleIntersectionTupleIntersectiontuple_intersection (Operator)

Name

tuple_intersectiontuple_intersectionTupleIntersectionTupleIntersectiontuple_intersection — Compute the intersection set of two input tuples.

Signature

Description

tuple_intersectiontuple_intersectionTupleIntersectionTupleIntersectiontuple_intersection returns the intersection set from Set1Set1Set1set1set_1 and Set2Set2Set2set2set_2 in IntersectionIntersectionIntersectionintersectionintersection. For example, if Set1Set1Set1set1set_1 contains the values [0,1,3,3,5] and Set2Set2Set2set2set_2 contains the values [2,3,5,10], the output IntersectionIntersectionIntersectionintersectionintersection is [3,5]. The operator also allows mixed types of elements in the input tuples. However, the elements with different types will be considered as different elements, i.e. 1.0 and 1 are different. Also, this means, if Set1Set1Set1set1set_1 and Set2Set2Set2set2set_2 have different types of elements, their intersection set could be empty. For example, if Set1Set1Set1set1set_1 contains the values [2,5,3] and Set2Set2Set2set2set_2 contains the values [2.0,5.0,0,10], the output IntersectionIntersectionIntersectionintersectionintersection is empty. Please note that the order of tuple elements resulting from tuple_intersectiontuple_intersectionTupleIntersectionTupleIntersectiontuple_intersection does not necessarily conform to the order in the input tuple.

Exception: Empty input tuples

If either or both of the input tuples are empty, the operator returns an empty tuple.

HDevelop In-line Operation

HDevelop provides an in-line operation for tuple_intersectiontuple_intersectionTupleIntersectionTupleIntersectiontuple_intersection, which can be used in an expression in the following syntax:

Intersection := intersection(Set1, Set2)

Execution Information

• Multithreading type: independent (runs in parallel even with exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Automatically parallelized on internal data level.

Parameters
