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]. 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. For example, the union of [2,5,3] and [4.0,5.0] is [2,5,3,4.0,5.0].

例外：空输入元组

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 内联操作

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)

执行信息

• 多线程类型：独立（即使使用独占算子也能并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 在内部数据级别上自动并行化。
