Scanner

Scanner is essentially¹ a parser that produces Tokens from a stream of characters. The tokens it produces are typically passed to parsers in TokenParsers.

Note: ¹ Scanner is really a Reader of Tokens

Linear Supertypes

Reader[Token], AnyRef, Any

Instance Constructors

new Scanner(in: String)

Convenience constructor (makes a character reader out of the given string)
new Scanner(in: Reader[Char])
