Module set
Set implementation for Lua
Functions
| intersection (t, other) | Compute the set intersection between two tables. |
| union (t, other) | Compute the set union of two tables. |
| difference (t, other) | Compute the (non-symmetric) difference of two tables. |
| symmetric_difference (t, other) | Compute the symmetric difference of two tables. |
| issubset (t, other) | Returns a boolean indicating whether the first table is a subset of the second. |
| isdisjoint (t, other) | Returns a boolean indicating whether the first table is disjoint with respect to the second. |
| equal (t, other) | Returns a boolean indicating whether the first table is equal to the second. |
| makeset (input) | Create a new Set object that allows the set methods from this module to be called directly on the set. |
Functions
- intersection (t, other)
-
Compute the set intersection between two tables.
Parameters:
- t A table
- other Another table
Returns:
-
A new table which contains the intersection between the two tables
- union (t, other)
-
Compute the set union of two tables.
Parameters:
- t A table
- other Another table
Returns:
-
A new table which contains the union of the two tables
- difference (t, other)
-
Compute the (non-symmetric) difference of two tables.
Parameters:
- t A table
- other Another table
Returns:
-
A new table which contains the difference between the two tables
- symmetric_difference (t, other)
-
Compute the symmetric difference of two tables.
Parameters:
- t A table
- other Another table
Returns:
-
A new table which contains the symmetric difference between the two
tables
- issubset (t, other)
-
Returns a boolean indicating whether the first table is a subset of the
second.
Parameters:
- t A table
- other Another table
Returns:
-
A boolean value
- isdisjoint (t, other)
-
Returns a boolean indicating whether the first table is disjoint with
respect to the second.
Parameters:
- t A table
- other Another table
Returns:
-
A boolean value
- equal (t, other)
-
Returns a boolean indicating whether the first table is equal to the second.
Parameters:
- t A table
- other Another table
Returns:
-
A boolean value
- makeset (input)
-
Create a new Set object that allows the set methods from this module to be
called directly on the set. The set itself is a table, where the keys are
the values contained in the set, and the values are the boolean value
`true`. The returned Set object will also have a `tostring()` method that
prints the values contained.
Parameters:
- input An input value to initialize the set with. If this is a Set instance, then it will properly take the value of the set - otherwise, the input is assumed to be a list-like table, and the values in this table are added to the set.
