名称

tuple_sem_typeT_tuple_sem_typeTupleSemTypeTupleSemTypetuple_sem_type — Return the semantic type of a tuple.

参数签名

tuple_sem_type( : : T : SemType)

描述

tuple_sem_typetuple_sem_typeTupleSemTypeTupleSemTypeTupleSemTypetuple_sem_type returns the semantic type of the input tuple TTTTtt. The type is returned as a string value in the output parameter SemTypeSemTypeSemTypeSemTypesemTypesem_type.

If TTTTtt contains only valid handles of the same type, the corresponding semantic type of the handles is returned. If it contains only valid or invalid handles, or handles of different type, 'handle'"handle""handle""handle""handle""handle" is returned. If TTTTtt contains elements of different types, 'any'"any""any""any""any""any" is returned.

Exception: Empty input tuple

If the input tuple is empty, the operator returns 'any'"any""any""any""any""any".

HDevelop In-line Operation

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

SemType := sem_type(T)

运行信息

Multithreading type: independent (runs in parallel even with exclusive operators).
Multithreading scope: global (may be called from any thread).
Processed without parallelization.

参数表

TTTTtt (input_control) tuple(-array) → (handle / real / integer / string)

Input tuple.

SemTypeSemTypeSemTypeSemTypesemTypesem_type (output_control) string → (string)

Semantic type of the input tuple as a string.

例程 (HDevelop)

create_matrix (3, 3, 0, MatrixID)
tuple_sem_type (MatrixID, SemType)
* SemType == 'matrix' (Handle of specific type)
clear_handle (MatrixID)
tuple_sem_type (MatrixID, SemType)
* SemType == 'handle' (Cleared handle)
tuple_sem_type ([MatrixID,123], SemType)
* SemType == 'any' (Mixed types)

结果

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