tuple_sem_typeT_tuple_sem_typeTupleSemTypeTupleSemType (Operator)


tuple_sem_typeT_tuple_sem_typeTupleSemTypeTupleSemType — Return the semantic type of a tuple.


tuple_sem_type( : : T : SemType)

Herror T_tuple_sem_type(const Htuple T, Htuple* SemType)

void TupleSemType(const HTuple& T, HTuple* SemType)

HTuple HTuple::TupleSemType() const

HString HHandle::TupleSemType() const

static void HOperatorSet.TupleSemType(HTuple t, out HTuple semType)

HTuple HTuple.TupleSemType()

string HHandle.TupleSemType()


tuple_sem_typetuple_sem_typeTupleSemTypeTupleSemTypeTupleSemType returns the semantic type of the input tuple TTTTt. The type is returned as a string value in the output parameter SemTypeSemTypeSemTypeSemTypesemType.

If TTTTt 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" is returned. If TTTTt contains elements of different types, '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".

Execution Information


TTTTt (input_control)  tuple(-array) HTupleHTupleHtuple (handle / real / integer / string) (HHandle / double / int / long / string) (HHandle / double / Hlong / HString) (handle / double / Hlong / char*)

Input tuple.

SemTypeSemTypeSemTypeSemTypesemType (output_control)  string HTupleHTupleHtuple (string) (string) (HString) (char*)

Semantic type of the input tuple as a string.

Example (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)


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