---

hasNext()

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

---

useDelimiter()

---

getIOException()

getIOException(): IOException|null

Get the last io exception (if does not occur then returns null)

---

reset()

reset(): void

Resets this scanner.

current(): string

Uses the result of the last called next() method

---

key()
