Lua Set

This work is devoted to God.

A library for working with sets. This library can save add-on developers some work.

Things included

• Set.new: a constructor for creating a new set.
• Set.create: a function for creating a set. Functionally the same as Set.new.

The following functions / methods can be called in two ways:

• When a set has been created with Set.new or Set.create then "add" for example can be called like this:

local set = Set.create()
set:add(1)

• Or by passing the set as first argument.

local set = Set.create()
set.add(set, 1)

This method also works for tables which fit the structure of set tables (just called set in other places in this documentation).

Functions / Methods:

• add: adds an element to the set.
• copy: copies a set.
• iterator: creates an iterator for the set.
• toList: creates a list out of the set.
• size: returns the number of elements in the set.
• contains: checks if the set contains a value.
• containsWhichFulfillsCondition: checks if the set contains an element which fulfills specific conditions.
• remove: removes an element from the set.
• intersect: creates an intersection of multiple sets.
• equals: checks if two sets are equal.
• union: creates a union of a set.
• hasElements: checks if a set has any elements.
• isEmpty: checks if a set is empty.
