__construct(?iterable $elements = null)

add(string|int|float|bool $x): void

Add an element to the disjoint set (no-op if present). scipy DisjointSet.add.

find(string|int|float|bool $x): string|int|float|bool

The root element value of $x (scipy __getitem__ / find).

merge(string|int|float|bool $x, string|int|float|bool $y): bool

Merge the subsets containing $x and $y. The smaller subset is attached to the larger; on a tie the earlier-inserted root wins. Returns true iff they were in different subsets. scipy merge.

connected(string|int|float|bool $x, string|int|float|bool $y): bool

Whether $x and $y are in the same subset. scipy connected.

subset(string|int|float|bool $x): array

The subset containing $x, as a list of element values in the subset's internal circular order (scipy returns a Python set; order is not significant). scipy subset.

subsetSize(string|int|float|bool $x): int

The size of the subset containing $x, without materializing it. scipy subset_size.

subsets(): array

All subsets, each a list of element values, in the order subsets are first encountered scanning elements by insertion order. scipy subsets.

count(): int

getIterator(): Traversable
