The Set class
(No version information available, might only be in Git)
Einführung
A Set is a sequence of unique values. This implementation uses the same hash table as Ds\Map, where values are used as keys and the mapped value is ignored.
Strengths
- Values can be any type, including objects.
- Supports array syntax (square brackets).
- Insertion order is preserved.
- Automatically frees allocated memory when its size drops low enough.
- add(), remove() and contains() are all O(1).
Weaknesses
- Doesn’t support push(), pop(), insert(), shift(), or unshift().
- get() is O(n) if there are deleted values in the buffer before the accessed index, O(1) otherwise.
