public class UnfoldingReader
extends java.io.PushbackReader

 $Id$ [06-Apr-2004]
 

A reader which performs iCalendar unfolding as it reads. Note that unfolding rules may be "relaxed" to allow unfolding of non-conformant *.ics files. By specifying the system property "ical4j.unfolding.relaxed=true" iCalendar files created with Mozilla Calendar/Sunbird may be correctly unfolded.

To wrap this reader with a BufferedReader you must ensure you specify an identical buffer size to that used in the BufferedReader.
