Sets¶
difference¶
Description |
Examples |
|---|---|
Arguments:
VALUES1(value-expression{1})
VALUES2(value-expression{1})
Returns the difference of the values in VALUES1 and VALUES2, i.e. the values
that are in VALUES1, but not in VALUES2. The values in VALUES1 that does not exist in
VALUES2 are kept in their original relative positions.
|
["difference",["list", "A", "B"], ["list", "B"]]Returns
["A"].["difference", "A", ["list", "B", "C"]]Returns
["A"].["difference",["list", "A", "B", "C", "D"],["list", "A", "B", "E"]]Returns
["C", "D"].["difference",["list", "D", "A", "D", "E", "B"],["list", "A", "F", "F", "B", "C"]]Returns
["D", "D", "E"]. |
intersection¶
Description |
Examples |
|---|---|
Arguments:
VALUES1(value-expression{1})
VALUES2(value-expression{1})
Returns the intersection of the values in VALUES1 and VALUES2, i.e. the values
that are in both VALUES1 and VALUES2. The values in VALUES1 that exist in
VALUES2 are kept in their original relative positions.
|
["intersection",["list", "A", "B"], ["list", "B", "C"]]Returns
["B"].["intersection", "B", ["list", "B", "C"]]Returns
["B"].["intersection", "A", ["list", "B", "C"]]Returns
[].["intersection",["list", "B", "C", "B", "D", "A"],["list", "A", "F", "F", "B", "E", "B", "C"]]Returns
["B", "C", "B", "A"]. |
intersects¶
Description |
Examples |
|---|---|
Arguments:
VALUES1(value-expression{1})
VALUES2(value-expression{1})
Same as
intersection, but returns a boolean value. Returns true if the two
arguments have values in common. |
["intersects",["list", "A", "B"], ["list", "B", "C"]]Returns
true.["intersects", "B", ["list", "B", "C"]]Returns
true.["intersects", "A", ["list", "B", "C"]]Returns
false. |
union¶
Description |
Examples |
|---|---|
Arguments:
VALUES1(value-expression{1})
VALUES2(value-expression{1})
Returns the union of the values in VALUES1 and VALUES2, i.e. the values that
are either in VALUES1 or in VALUES2. The values in VALUES1 are returned first and kept
in their original relative positions and after that the values in VALUES2 are kept in
their original relative positions. Only the first occurrence of a value is returned.
|
["union",["list", "A", "B"], ["list", "B", "C"]]Returns
["A", "B", "C"].["union", "A", ["list", "B", "C"]]Returns
["A", "B", "C"].["union",["list", "B", "C", "B", "D", "A"],["list", "A", "F", "F", "B", "E", "B", "C"]]Returns
["B", "C", "D", "A", "F", "E"]. |
