名称

tuple_is_string_elemtuple_is_string_elemTupleIsStringElemTupleIsStringElemtuple_is_string_elem — Test whether the types of the elements of a tuple are of type string.

签名

tuple_is_string_elem( : : T : IsString)

描述

tuple_is_string_elemtuple_is_string_elemTupleIsStringElemTupleIsStringElemTupleIsStringElemtuple_is_string_elem tests the elements of the input tuple TTTTtt separately. For all elements of type string the value 1 (true) is returned in IsStringIsStringIsStringIsStringisStringis_string, else 0 (false) is returned.

例外：空输入元组

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

HDevelop 内联操作

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

IsString := is_string_elem(T)

执行信息

Multithreading type: independent (runs in parallel even with exclusive operators).
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

TTTTtt (输入控制) tuple(-array) → (string / real / integer / handle)

Input tuple.

IsStringIsStringIsStringIsStringisStringis_string (输出控制) number(-array) → (integer)

Are the elements of the input tuple of type string?

示例（HDevelop）

tuple_is_string_elem ([3.1416,'pi',3], IsString)
* IsString = [false, true, false]

结果

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