               int bufferSize)

Creates a new LineInputStream to read data from the specified input stream.

Parameters:

in - the underlying input stream

bufferSize - the (initial) size of the internal buffer

Throws:

java.lang.IllegalArgumentException - if bufferSize <= 0

Method Detail

readLine

public java.lang.String readLine()
                          throws java.io.IOException

Reads a line of text. A line is considered to be terminated by any one of a line feed ('\n'), a carriage return ('\r'), or a carriage return followed immediately by a linefeed.

Returns:

a String containing the contents of the line, not including any line-termination characters, or null if the end of the stream has been reached

Throws:

java.io.IOException - if an I/O error occurs

getLineDelimiter

public byte[] getLineDelimiter()

Returns the line delimiter of the line just read.

Returns:

the line delimiter

getBuffer

public byte[] getBuffer()
                 throws java.io.IOException

Returns the data in the buffer.

Returns:

the data in the buffer

Throws:

java.io.IOException
