tuple_replace — Replaces one or more elements of a tuple.
tuple_replace( : : Tuple, Index, ReplaceTuple : Replaced)
tuple_replace replaces one or more elements of the
input tuple Tuple and returns them with Replaced.
At this, Index determines the indices of the elements
and ReplaceTuple the corresponding values to replace.
The parameter Index must contain one or more integer values
(any floating point number must represent an integer value without
fraction). Indices of tuple elements start at 0. Therefore, the first
tuple element has got the index 0. If ReplaceTuple contains only
one value, this value will be replaced at all indices of Index.
If a value of Index is greater than the length of the input
tuple Tuple, Replaced will be extended accordingly and
initialized with zeros. For example, if Tuple contains [1],
Index contains the values [2,4], and ReplaceTuple
contains the values [3,5], Replaced will be [1,0,3,0,5].
It is allowed to mix strings and numbers in the input tuples
Tuple and ReplaceTuple.
If either Index or ReplaceTuple is empty and the other is
not, an exception is raised. If both are empty, the output tuple
Replaced corresponds to the input Tuple. If both are
empty, but the input Tuple is not, the empty tuple will be
extended as described above.
HDevelop provides an in-line operation for tuple_replace,
which can be used in an expression in the following syntax:
Replaced := replace(Tuple, Index, ReplaceTuple)
Tuple (input_control) tuple(-array) → (integer / real / string)
Input tuple.
Index (input_control) integer(-array) → (integer)
Index/Indices of elements to be replaced.
ReplaceTuple (input_control) tuple(-array) → (integer / real / string)
Element(s) to replace.
Replaced (output_control) tuple-array → (integer / real / string)
Tuple with replaced elements.
