hasNext(php\util\Regex $pattern): bool

---

next()

next(php\util\Regex $pattern): string|null

---

nextLine()

nextLine(): string|null

---

hasNextLine()

hasNextLine(): bool

---

nextInt()

nextInt(null|int $radix): int|null

---

hasNextInt()

hasNextInt(null|int $radix): bool

---

nextDouble()

nextDouble(): float|null

---

hasNextDouble()

hasNextDouble(): bool

---

skip()

skip(php\util\Regex $pattern): bool
