TextRankOptions.GetHashCode

A hash consistent with the equality, in constant time.

public int GetHashCode()

Returns — a hash over the scalars and whether stop words are present.

Example — options equal as sets hash alike.

using Lodestar.Text.Keywords;

TextRankOptions left = new() { StopWords = ["the", "the"] };
TextRankOptions right = new() { StopWords = ["the"] };

bool alike = left.GetHashCode() == right.GetHashCode();  // => True

Remarks — the stop words contribute only their presence, never their count, because set equality does not preserve a count and equal objects must hash alike. An absent Words limit contributes -1, so it does not collide with a limit of zero.

Applies to — net10.0, netstandard2.0.
