名称

tuple_is_inttuple_is_intTupleIsIntTupleIsInttuple_is_int — Test if the internal representation of a tuple is of type integer.

描述

tuple_is_inttuple_is_intTupleIsIntTupleIsIntTupleIsInttuple_is_int tests if the internal representation of the input tuple TTTTtt is of type integer. In that case the value 1 (true) is returned in IsIntIsIntIsIntIsIntisIntis_int, otherwise the value 0 (false) is returned. If a tuple consists of integer elements only, IsIntIsIntIsIntIsIntisIntis_int can nevertheless be 0 in case the internal representation is H_TYPE_MIXED; see tuple_typetuple_typeTupleTypeTupleTypeTupleTypetuple_type for details.

例外：空输入元组

If the input tuple is empty, the operator returns 1.

HDevelop 内联操作

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

IsInt := is_int(T)

注意

Even if all tuple elements are of type integer, tuple_is_inttuple_is_intTupleIsIntTupleIsIntTupleIsInttuple_is_int returns 0 (false) if the internal representation of the tuple is of type H_TYPE_MIXED. To test if the elements of the tuple are of type integer the operator tuple_is_int_elemtuple_is_int_elemTupleIsIntElemTupleIsIntElemTupleIsIntElemtuple_is_int_elem should be used.

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）。
• 未采用并行化处理。

参数

示例（HDevelop）

tuple_is_int ([3.1416,'pi',3], IsIntA)
* IsIntA = false
tuple_is_int ([1,2,3], IsIntB)
* IsIntB = true
tuple_is_int ([], IsIntC)
* IsIntC = true

结果

如果参数有效，算子 tuple_is_inttuple_is_intTupleIsIntTupleIsIntTupleIsInttuple_is_int 返回值 2 ( H_MSG_TRUE )。
