Public Methods

• ->concat<Tu super Tv>(Traversable<Tu> $traversable): ConstVector<Tu>
  Returns a ConstVector that is the concatenation of the values of the current ConstSet and the values of the provided Traversable
• ->filter((function(Tv): bool) $fn): ConstSet<Tv>
  Returns a ConstSet containing the values of the current ConstSet that meet a supplied condition applied to each value
• ->filterWithKey((function(arraykey, Tv): bool) $fn): ConstSet<Tv>
  Returns a ConstSet containing the values of the current ConstSet that meet a supplied condition applied to its "keys" and values
• ->firstKey(): ?arraykey
  Returns the first "key" in the current ConstSet
• ->firstValue(): ?Tv
  Returns the first value in the current ConstSet
• ->keys(): ConstVector<arraykey>
  Returns a ConstVector containing the values of the current ConstSet
• ->lastKey(): ?arraykey
  Returns the last "key" in the current ConstSet
• ->lastValue(): ?Tv
  Returns the last value in the current ConstSet
• ->map<Tu as arraykey>((function(Tv): Tu) $fn): ConstSet<Tu>
  Returns a ConstSet containing the values after an operation has been applied to each value in the current ConstSet
• ->mapWithKey<Tu as arraykey>((function(arraykey, Tv): Tu) $fn): ConstSet<Tu>
  Returns a ConstSet containing the values after an operation has been applied to each "key" and value in the current Set
• ->skip(int $n): ConstSet<Tv>
  Returns a ConstSet containing the values after the n-th element of the current ConstSet
• ->skipWhile((function(Tv): bool) $fn): ConstSet<Tv>
  Returns a ConstSet containing the values of the current ConstSet starting after and including the first value that produces true when passed to the specified callback
• ->slice(int $start, int $len): ConstSet<Tv>
  Returns a subset of the current ConstSet starting from a given key up to, but not including, the element at the provided length from the starting key
• ->take(int $n): ConstSet<Tv>
  Returns a ConstSet containing the first n values of the current ConstSet
• ->takeWhile((function(Tv): bool) $fn): ConstSet<Tv>
  Returns a ConstSet containing the values of the current ConstSet up to but not including the first value that produces false when passed to the specified callback
• ->toDArray(): darray<Tv, Tv>
• ->toVArray(): varray<Tv>
• ->values(): ConstVector<Tv>
  Returns a ConstVector containing the values of the current ConstSet
• ->zip<Tu>(Traversable<Tu> $traversable): ConstSet<nothing>
  Returns a ConstSet where each value is a Pair that combines the value of the current ConstSet and the provided Traversable
