public class Log

extends Object

Pluggable logging framework that allows a developer to log into storage using the file connector API. It is highly recommended to use this class coupled with Netbeans preprocessing tags to reduce its overhead completely in runtime.

Field Summary

static int	DEBUG Constant indicating the logging level Debug is the default and the lowest level followed by info, warning and error.
static int	ERROR Constant indicating the logging level Debug is the default and the lowest level followed by info, warning and error.
static int	INFO Constant indicating the logging level Debug is the default and the lowest level followed by info, warning and error.
static int	WARNING Constant indicating the logging level Debug is the default and the lowest level followed by info, warning and error.

Constructor Summary

Log()

Method Summary

protected Writer	createWriter() Default method for creating the output writer into which we write, this method creates a simple log file using the file connector.
static int	getLevel() Returns the logging level for printing log details, the lower the value the more verbose would the printouts be.
protected String	getThreadAndTimeStamp() Returns a simple string containing a timestamp and thread name.
static void	install(Log newInstance) Installs a log subclass that can replace the logging destination/behavior.
static void	p(String text) Default println method invokes the print instance method, uses DEBUG level.
static void	p(String text, int level) Default println method invokes the print instance method, uses given level.
protected void	print(String text, int level) Default log implementation prints to the console and the file connector if applicable.
static void	setLevel(int level) Sets the logging level for printing log details, the lower the value the more verbose would the printouts be.
static void	showLog() Places a form with the log as a TextArea on the screen, this method can be attached to appear at a given time or using a fixed global key.

text - the text to print

level - one of DEBUG, INFO, WARNING, ERROR

createWriter

protected Writer createWriter()
                       throws IOException

Default method for creating the output writer into which we write, this method creates a simple log file using the file connector.

Returns:

the output writer.

Throws:

IOException - if the output writer could not be created.

getThreadAndTimeStamp

protected String getThreadAndTimeStamp()

Returns a simple string containing a timestamp and thread name.

Returns:

the timestamp and thread name

setLevel

getLevel

public static int getLevel()

Returns the logging level for printing log details, the lower the value the more verbose would the printouts be.

Returns:

one of DEBUG, INFO, WARNING, ERROR

See Also:

setLevel(int)

showLog

public static void showLog()

Places a form with the log as a TextArea on the screen, this method can be attached to appear at a given time or using a fixed global key. Using this method might cause a problem with further log output.
