Class StandardLogChannel  

java.lang.Object
  com.lutris.logging.StandardLogChannel

All Implemented Interfaces:

LogChannel

---

public class StandardLogChannel

extends java.lang.Object

implements LogChannel

Standard implementation of a channel associated with a logging facility. All messages for the facility are written using a channel. Care is take to avoid synchronization when possible for performance reasons.

---

Field Summary
private static java.text.SimpleDateFormat	dateFormatter           Format for the date.
private  java.lang.String	facility           Our symbolic name.
private  StandardLogger	logger           Logger object with which we are associated.

 

Constructor Summary
protected	StandardLogChannel(java.lang.String chanFacility, StandardLogger loggerObj)           Construct a new log channel.

 

Method Summary
private  void	doWrite(java.io.PrintWriter out, java.util.Date date, int level, java.lang.String msg)           Do the work of writting a log message.
int	getLevel(java.lang.String level)           Convert a symbolic level to an integer identifier.
LogWriter	getLogWriter(int level)           Create a LogWrite associated with a particular level.
LogWriter	getLogWriter(java.lang.String level)           Create a LogWrite associated with a particular level.
boolean	isEnabled(int level)           Determine if logging is enabled for the specified level.
boolean	isEnabled(java.lang.String level)           Determine if logging is enabled for the specified level.
void	write(int level, java.lang.String msg)           Write a string to the log file.
void	write(int level, java.lang.String msg, java.lang.Throwable throwable)           Write a string and exception to the log file.
void	write(java.lang.String level, java.lang.String msg)           Write a string to the log file.

Field Detail

facility

private java.lang.String facility

Our symbolic name.

---

dateFormatter

private static final java.text.SimpleDateFormat dateFormatter

Format for the date.

---

logger

private StandardLogger logger

Logger object with which we are associated.

Constructor Detail

StandardLogChannel

protected StandardLogChannel(java.lang.String chanFacility,
                             StandardLogger loggerObj)

Construct a new log channel.

Method Detail

getLevel

public int getLevel(java.lang.String level)

Description copied from interface: LogChannel

Convert a symbolic level to an integer identifier.

Specified by:

getLevel in interface LogChannel

---

getLogWriter

public LogWriter getLogWriter(java.lang.String level)

Description copied from interface: LogChannel

Create a LogWrite associated with a particular level. This is often an easier object to use than a LogChannel if limited levels are needed.

Specified by:

getLogWriter in interface LogChannel

---

getLogWriter

public LogWriter getLogWriter(int level)

Description copied from interface: LogChannel

Create a LogWrite associated with a particular level. This is often an easier object to use than a LogChannel if limited levels are needed.

Specified by:

getLogWriter in interface LogChannel

---

isEnabled

public boolean isEnabled(int level)

Description copied from interface: LogChannel

Determine if logging is enabled for the specified level. This is useful to prevent a series of unnecessary logging calls, as often encountered with debug logging, or a call where generating the message is expensive.

Specified by:

isEnabled in interface LogChannel

---

isEnabled

public boolean isEnabled(java.lang.String level)

Description copied from interface: LogChannel

Determine if logging is enabled for the specified level. This is useful to prevent a series of unnecessary logging calls, as often encountered with debug logging, or a call where generating the message is expensive.

Specified by:

isEnabled in interface LogChannel

---

doWrite

private void doWrite(java.io.PrintWriter out,
                     java.util.Date date,
                     int level,
                     java.lang.String msg)

Do the work of writting a log message. It should already be determined if the channel is enabled; but limited synchronization is required, as we ignore any error while writing. Handles multiline messages.

---

write

public void write(int level,
                  java.lang.String msg)

Description copied from interface: LogChannel

Write a string to the log file.

Specified by:

write in interface LogChannel

---

write

public void write(java.lang.String level,
                  java.lang.String msg)

Description copied from interface: LogChannel

Write a string to the log file.

Specified by:

write in interface LogChannel

---

write

public void write(int level,
                  java.lang.String msg,
                  java.lang.Throwable throwable)

Description copied from interface: LogChannel

Write a string and exception to the log file.

Specified by:

write in interface LogChannel

---

write

public void write(java.lang.String level,
                  java.lang.String msg,
                  java.lang.Throwable throwable)

Description copied from interface: LogChannel

Write a string and exception to the log file.

Specified by:

write in interface LogChannel
