名称

tuple_uniontuple_unionTupleUnionTupleUniontuple_union — Compute the union set of two input tuples.

参数签名

描述

tuple_uniontuple_unionTupleUnionTupleUnionTupleUniontuple_union returns the union set from Set1Set1Set1Set1set1set_1 and Set2Set2Set2Set2set2set_2 in UnionUnionUnionUnionunionunion. For example, if Set1Set1Set1Set1set1set_1 contains the values [0,1,3,3,5] and Set2Set2Set2Set2set2set_2 contains the values [3,4], the output UnionUnionUnionUnionunionunion is [0,1,3,4,5]. 该算子 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. For example, the union of [2,5,3] and [4.0,5.0] is [2,5,3,4.0,5.0].

Exception: Empty input tuples

If both of the input tuples are empty, 该算子 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_uniontuple_unionTupleUnionTupleUnionTupleUniontuple_union, which can be used in an expression in the following syntax:

Union := union(Set1, Set2)

运行信息

• Multithreading type: independent (runs in parallel even with exclusive operators).
• 多线程作用域:全局(可以从任何线程调用)。
• Automatically parallelized on internal data level.
