FileController

public FileController(String pathToLogFile,
 int singleFileLogSize,
 int logFileRotations,
 boolean appendMode)
               throws IOException,
SecurityException

Pass-through constructor ensuring we will use the desired custom formatter, and match ALL records.

Parameters:

pathToLogFile - The pattern to match for the logfile's title.

singleFileLogSize - This is the max file size before the logger will rotate files (in regular Bytes).

logFileRotations - This is the max number of log files to keep in rotation before overwriting the first one.

appendMode - Should always be true to ensure we are in append mode.

Throws:

IOException - Thrown if we cannot find the location or there is an error getting it.

SecurityException - Thrown if we do not have the correct permissions to be writing to this location.
