Class LineInputStream

com.sun.mail.util.LineInputStream
- All Implemented Interfaces:
- Closeable
public class LineInputStream
- extends FilterInputStream
This class is to support reading CRLF terminated lines that
contain only US-ASCII characters from an input stream. Provides
functionality that is similar to the deprecated
DataInputStream.readLine()
. Expected use is to read
lines as String objects from a RFC822 stream.
It is implemented as a FilterInputStream, so one can just wrap
this class around any input stream and read bytes from this filter.

LineInputStream
public LineInputStream(InputStream in)
readLine
public String readLine()
throws IOException
- Read a line containing only ASCII characters from the input
stream. A line is terminated by a CR or NL or CR-NL sequence.
A common error is a CR-CR-NL sequence, which will also terminate
a line.
The line terminator is not returned as part of the returned
String. Returns null if no data is available.
This class is similar to the deprecated
DataInputStream.readLine()
- Throws:
IOException
