Constructors
-
Forceset
()¶ Default constructor.
-
Forceset
(set) Copy constructor.
Parameters: set (BWAPI.Forceset) – The Forceset to copy.
-
Forceset
(tbl) Constructor to convert a Lua table to a set. Any values in the table that are of type
Force
are added to the set.Parameters: tbl (table) – A table containing Force
objects.
Member Functions
-
getPlayers
() → set¶ Retrieves the set of players that belong to this set of forces.
Returns: A Playerset
containing the players that are part of this Forceset.Return type: BWAPI.Playerset
-
iterator
() → iteratorFunction¶ Returns an iterator function intended to be used in
for
loops (e.g.for item in set:iterator() do
).Returns: An iterator function that will return the next value in the set with each successive call. Return type: function
-
asTable
() → table¶ Returns the values of the set as an array-like Lua table.
Note
The ordering of the returned table is arbitrary (due to sets being unordered in the C++ implementation).
Returns: An array-like Lua table containing each value in the set. Return type: table
-
count
(val) → int¶ Searches the set for elements with a value of
val
and returns the number of elements found. Because sets do not allow for duplicate values, this means that the function will return either1
or0
. Because of this, it’s recommended to usecontains()
instead.See also
-
contains
(val) → boolean¶ Checks if this set contains a specific value.
Returns: true
if the set contains the specified value, orfalse
otherwise.Return type: boolean
-
size
() → int¶ Returns: The number of values in the set. Return type: int Note
set:size()
is exactly equivalent to#set
-
empty
() → boolean¶ Returns: true
if the set is empty (size() == 0
), orfalse
otherwise.Return type: boolean
-
insert
(val)¶ Inserts the value into the set.
Note
Sets cannot contain duplicate values. If the value already exists in the set, the set will not be modified.
-
erase
(val) → numElementsErased¶ Removes
val
from the set if it exists.Returns: The number of elements removed. Because sets do not allow for duplicate values, this means that the function will return either 1
or0
.Return type: int
-
clear
()¶ Removes all elements from the set, leaving it with a size of 0.
-
eraseIf
(pred)¶ Iterates the set and erases each element x where pred(x) returns true. The set is modified in place.
Parameters: pred (function) – A predicate function that takes a value and returns true
for values that should be erased andfalse
otherwise.
-
filter
(pred)¶ Iterates the set and erases each element x where pred(x) returns false. The set is modified in place.
Parameters: pred (function) – A predicate function that takes a value and returns true
for values that should be kept andfalse
for elements that should be erased.
