Description

tuple_symmdifftuple_symmdiffTupleSymmdiffTupleSymmdifftuple_symmdiff returns the symmetric difference set from Set1Set1Set1set1set_1 and Set2Set2Set2set2set_2 in SymmDiffSymmDiffSymmDiffsymmDiffsymm_diff. 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 SymmDiffSymmDiffSymmDiffsymmDiffsymm_diff is [0,1,2,10]. 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 symmetric difference set could be the union. For example, if Set1Set1Set1set1set_1 contains the values [2,5,3] and Set2Set2Set2set2set_2 contains the values [2.0,5.0], the output SymmDiffSymmDiffSymmDiffsymmDiffsymm_diff is [2,3,5,2.0,5.0]. Please note that the order of tuple elements resulting from tuple_symmdifftuple_symmdiffTupleSymmdiffTupleSymmdifftuple_symmdiff does not necessarily conform to the order in the input tuple.

Exception: Empty input tuples

If both of the input tuples are empty, the operator returns an empty tuple. If one of the input tuples is empty and the other is not, the output corresponds to the input tuple that is not empty.

HDevelop In-line Operation

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

SymmDiff := symmdiff(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.
