Public Methods

• ->concat<Tu super Tv>(Traversable<Tu> $traversable): ConstVector<Tu>
  Returns a ConstVector that is the concatenation of the values of the current ConstVector and the values of the provided Traversable
• ->filter((function(Tv): bool) $fn): ConstVector<Tv>
  Returns a ConstVector containing the values of the current ConstVector that meet a supplied condition
• ->filterWithKey((function(int, Tv): bool) $fn): ConstVector<Tv>
  Returns a ConstVector containing the values of the current ConstVector that meet a supplied condition applied to its keys and values
• ->firstKey(): ?int
  Returns the first key in the current ConstVector
• ->firstValue(): ?Tv
  Returns the first value in the current ConstVector
• ->keys(): ConstVector<int>
  Returns a ConstVector containing the keys of the current ConstVector
• ->lastKey(): ?int
  Returns the last key in the current ConstVector
• ->lastValue(): ?Tv
  Returns the last value in the current ConstVector
• ->linearSearch(mixed $search_value): int
  Returns the index of the first element that matches the search value
• ->map<Tu>((function(Tv): Tu) $fn): ConstVector<Tu>
  Returns a ConstVector containing the values after an operation has been applied to each value in the current ConstVector
• ->mapWithKey<Tu>((function(int, Tv): Tu) $fn): ConstVector<Tu>
  Returns a ConstVector containing the values after an operation has been applied to each key and value in the current ConstVector
• ->skip(int $n): ConstVector<Tv>
  Returns a ConstVector containing the values after the n-th element of the current ConstVector
• ->skipWhile((function(Tv): bool) $fn): ConstVector<Tv>
  Returns a ConstVector containing the values of the current ConstVector starting after and including the first value that produces true when passed to the specified callback
• ->slice(int $start, int $len): ConstVector<Tv>
  Returns a subset of the current ConstVector starting from a given key up to, but not including, the element at the provided length from the starting key
• ->take(int $n): ConstVector<Tv>
  Returns a ConstVector containing the first n values of the current ConstVector
• ->takeWhile((function(Tv): bool) $fn): ConstVector<Tv>
  Returns a ConstVector containing the values of the current ConstVector up to but not including the first value that produces false when passed to the specified callback
• ->toDArray(): darray<int, Tv>
• ->toVArray(): varray<Tv>
• ->values(): ConstVector<Tv>
  Returns a ConstVector containing the values of the current ConstVector
• ->zip<Tu>(Traversable<Tu> $traversable): ConstVector<Pair<Tv, Tu>>
  Returns a ConstVector where each element is a Pair that combines the element of the current ConstVector and the provided Traversable
