public class LogOutputStream
extends LineProcOutputStream

Class LogOutputStream defines an output stream that sends data to a LogFile object. 7/1/2003 -- [HS] Initial version. 7/9/2003 -- [ET] Fixed extra-newline added to each line of output; added 'closeLogFile()' and 'setCloseLogFileFlag()' methods; added overridden 'close()' method.

Field Summary

protected boolean	closeLogFileFlag Flag set 'true' to close LogFile when this output stream is closed.
protected int	logLevel The logging level to use.
protected LogFile	outFile The LogFile object to use.

Constructor Summary

LogOutputStream(LogFile logFileObj)
Creates an output stream that sends data to a LogFile object.

Method Summary

void	callBackMethod(java.lang.String s) Implements the CallbackStringParam interface.
void	close() Overidden version that also flushes any buffered data and closes the LogFile object (if 'closeLogFileFlag' is 'true').
void	closeLogFile() Closes the LogFile used by this object.
LogFile	getLogfile() Returns a reference to the logfile in use.
void	setCloseLogFileFlag(boolean flgVal) Configures whether or not the 'LogFile' object held by this output stream will be closed when the stream is closed.
void	setLoggingLevel(int newLevel) Set the logging level used for outputs to the log file.

Implements the CallbackStringParam interface.

Parameters:

s - string parameter to use.

getLogfile

public LogFile getLogfile()

Returns a reference to the logfile in use.

Returns:

the LogFile instance that this instance logs to.

setLoggingLevel

public void setLoggingLevel(int newLevel)

Set the logging level used for outputs to the log file.

Parameters:

newLevel - the new logging level.

setCloseLogFileFlag

public void setCloseLogFileFlag(boolean flgVal)

Configures whether or not the 'LogFile' object held by this output stream will be closed when the stream is closed. The default behavior is for the 'LogFile' object to be closed.

Parameters:

flgVal - true to close the 'LogFile' object when this output stream is closed; false to not.
