[source: scala/util/parsing/combinator/lexical/Scanners.scala]
class Scanner(in : Reader[Char])

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

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.
