tuple_str_last_ntuple_str_last_nTupleStrLastNTupleStrLastNtuple_str_last_n (Operator)

Name

tuple_str_last_ntuple_str_last_nTupleStrLastNTupleStrLastNtuple_str_last_n — Cut all characters starting at position “n” out of a string tuple.

Signature

Description

tuple_str_last_ntuple_str_last_nTupleStrLastNTupleStrLastNtuple_str_last_n cuts all characters from position “n” to the end of the string out of each string of the input tuple StringStringStringstringValstring and returns them as new strings in the output tuple SubstringSubstringSubstringsubstringsubstring. The position “n” is determined by the second input tuple PositionPositionPositionpositionposition. If PositionPositionPositionpositionposition only contains one element, this element contains “n”. If StringStringStringstringValstring and PositionPositionPositionpositionposition have got the same number of elements, the first element of PositionPositionPositionpositionposition determines the start position for the first string of StringStringStringstringValstring, the second element of PositionPositionPositionpositionposition does so for the second string of StringStringStringstringValstring and so on. If PositionPositionPositionpositionposition contains more than one element and StringStringStringstringValstring contains only one string, tuple_str_last_ntuple_str_last_nTupleStrLastNTupleStrLastNtuple_str_last_n cuts more than one substrings out of this string. The elements of PositionPositionPositionpositionposition then determine the start positions for these substrings. If both input tuples contain more than one element but differ in the number of elements, tuple_str_last_ntuple_str_last_nTupleStrLastNTupleStrLastNtuple_str_last_n returns an error.

If both input tuples are empty, the operator returns an empty tuple. Similarly, if StringStringStringstringValstring is empty and PositionPositionPositionpositionposition is not, the operator returns an empty tuple. In contrast, if PositionPositionPositionpositionposition is empty and StringStringStringstringValstring is not, an exception is raised.

Unicode code points versus bytes

The position references Unicode code points. One Unicode code point may be composed of multiple bytes in the UTF-8 string. If the position should reference the raw bytes of the string, this operator can be switched to byte mode with set_system('tsp_tuple_string_operator_mode','byte')set_system("tsp_tuple_string_operator_mode","byte")SetSystem("tsp_tuple_string_operator_mode","byte")SetSystem("tsp_tuple_string_operator_mode","byte")set_system("tsp_tuple_string_operator_mode","byte"). If 'filename_encoding'"filename_encoding""filename_encoding""filename_encoding""filename_encoding" is set to 'locale'"locale""locale""locale""locale" (legacy), this operator always uses the byte mode.

HDevelop In-line Operation

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

Substring := str_lastn(String, Position)

Execution Information

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