class Scanner

[source: scala/util/parsing/combinatorold/lexical/Scanners.scala]

class Scanner(in : Reader[Char]): extends Reader[Token]

Scanner is essentially(*) a parser that produces `Token's from a stream of characters. The tokens it produces are typically passed to parsers in TokenParsers.

Note: (*) Scanner is really a `Reader' of `Token's

Additional Constructor Summary
`def`	this (in : java.lang.String) : Scanner Convenience constructor (makes a character reader out of the given string)

Method Summary
`def`	atEnd : Boolean true iff there are no more elements in this reader
`def`	first : Token Returns the first element of the reader
`override def`	offset : Int
`def`	pos : Position The position of the first element in the reader
`def`	rest : Scanner Returns an abstract reader consisting of all elements except the first
`override def`	source : java.lang.CharSequence If this is a reader over character sequences, the underlying char sequence If not, throws a `NoSuchMethodError` exception.
