tuple_intersectiontuple_intersectionTupleIntersectiontuple_intersectionTupleIntersectionTupleIntersection (Operator)

Name

tuple_intersectiontuple_intersectionTupleIntersectiontuple_intersectionTupleIntersectionTupleIntersection — Compute the intersection set of two input tuples.

Signature

Description

tuple_intersectiontuple_intersectionTupleIntersectiontuple_intersectionTupleIntersectionTupleIntersection returns the intersection set from Set1Set1Set1Set1Set1set1 and Set2Set2Set2Set2Set2set2 in IntersectionIntersectionIntersectionIntersectionIntersectionintersection. For example, if Set1Set1Set1Set1Set1set1 contains the values [0,1,3,3,5] and Set2Set2Set2Set2Set2set2 contains the values [2,3,5,10], the output IntersectionIntersectionIntersectionIntersectionIntersectionintersection 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 Set1Set1Set1Set1Set1set1 and Set2Set2Set2Set2Set2set2 have different types of elements, their intersection set could be empty. For example, if Set1Set1Set1Set1Set1set1 contains the values [2,5,3] and Set2Set2Set2Set2Set2set2 contains the values [2.0,5.0,0,10], the output IntersectionIntersectionIntersectionIntersectionIntersectionintersection is empty.

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_intersectionTupleIntersectiontuple_intersectionTupleIntersectionTupleIntersection, which can be used in an expression in the following syntax:

Intersection := intersection(Set1, Set2)

Parallelization

• 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

Result

If the parameters are valid, the operator tuple_intersectiontuple_intersectionTupleIntersectiontuple_intersectionTupleIntersectionTupleIntersection returns the value 2 (H_MSG_TRUE).
