Constructor Detail

BufferedLineReader

public BufferedLineReader(String last_line)

Buffer characters until a whole line can be read.

Parameters:

last_line - Used to detect the end of usable data (instead of a null).

BufferedLineReader

public BufferedLineReader(long inactivity_timeout,
                          String last_line)

Buffer characters until a whole line can be read, but insist that data is actively arriving.

Parameters:

inactivity_timeout - Max milliseconds to detect each line of data.

last_line - Used to detect the end of usable data (instead of a null).

Method Detail

write

public void write(int b)

Required public by the parent OutputStream class. Write one byte.

Parameters:

b - One byte.

createPrintStream

public PrintStream createPrintStream()

Allows for output to be read before execution completes.

Returns:

Given to the ProcessLauncher class.

readNextLine

public String readNextLine()
                    throws IOException

Read a whole line (an actual line terminator was found).

Returns:

A whole line.

Throws:

IOException - An error occured.

closeAll

public void closeAll()

Used to close prior to reading the lastLineInOutputStream.

getBufferedReader

private BufferedReader getBufferedReader()

getInputStream

private InputStream getInputStream()

readOneLineWithTimer

private String readOneLineWithTimer(long max_time_diff)
                             throws IOException,
                                    BufferedLineReader.InactivityException

Used only if the inactivity timeout is non-zero.

Throws:

IOException

BufferedLineReader.InactivityException
