Value Summary
protected var ccol : Int
var ch : Char
the last character returned by next. the value before the first call to next is undefined.
protected var cline : Int
var descr : java.lang.String
description of this source, default empty
protected abstract val iter : Iterator[Char]
the actual iterator
var nerrors : Int
var nwarnings : Int
var pos : Int
position of last character returned by next
var tabinc : Int
default col increment for tabs '\t', set to 4 initially
Method Summary
def getLine (line : Int) : java.lang.String
convenience method, returns given line (not including newline) from Source.
def getLines : Iterator[java.lang.String]
returns an iterator who returns lines (including newline character). a line ends in \n.
def hasNext : Boolean
Returns true if this source has more characters.
def next : Char
returns next character and has the following side-effects: updates position (ccol and cline) and assigns the character to ch
def report (pos : Int, msg : java.lang.String, out : java.io.PrintStream) : Unit
def reportError (pos : Int, msg : java.lang.String, out : java.io.PrintStream) : Unit
Reports an error message to the output stream out.
def reportWarning (pos : Int, msg : java.lang.String, out : java.io.PrintStream) : Unit
abstract def reset : Source
The reset() method creates a fresh copy of this Source.
