tuple_symmdiff
— Compute the symmetric difference set of two input tuples.
tuple_symmdiff
returns the symmetric difference set from
Set1
and Set2
in SymmDiff
. For example,
if Set1
contains the values [0,1,3,3,5] and Set2
contains the values [2,3,5,10], the output SymmDiff
is [0,1,2,10].
The operator also allows mixed types of elements in the input tuples.
However, the elements with different types will be considered as
different elements, i.e. 1.0 and 1 are different. Also, this means, if
Set1
and Set2
have different types of elements, their
symmetric difference set could be the union. For example, if Set1
contains the values [2,5,3] and Set2
contains the values [2.0,5.0],
the output SymmDiff
is [2,5,3,2.0,5.0].
If both of the input tuples are empty, the operator returns an empty tuple. If one of the input tuples is empty and the other is not, the output corresponds to the input tuple that is not empty.
HDevelop provides an in-line operation for tuple_symmdiff
,
which can be used in an expression in the following syntax:
SymmDiff := symmdiff(Set1, Set2)
Set1
(input_control) tuple(-array) →
(integer / real / string / handle)
Input tuple.
Set2
(input_control) tuple(-array) →
(integer / real / string / handle)
Input tuple.
SymmDiff
(output_control) tuple(-array) →
(integer / real / string / handle)
The symmetric difference set of two input tuples.
If the parameters are valid, the operator
tuple_symmdiff
returns the value 2 (H_MSG_TRUE).
