class StreamReader

[source: scala/util/parsing/input/StreamReader.scala]

sealed class StreamReader(seq : PagedSeq[Char], off : Int, lnum : Int): extends PagedSeqReader

A StreamReader reads from a character sequence, typically created as a PagedSeq from a java.io.Reader NOTE: StreamReaders do not really fulfill the new contract for readers, which requires a `source' CharSequence representing the full input. Instead source is treated line by line. As a consequence, regex matching cannot extend beyond a single line when a StreamReader are used for input. If you need to match regexes spanning several lines you should consider class PagedSeqReader instead.
