Class WriterLogger

java.lang.Object

WriterLogger

All Implemented Interfaces:

Logger

public class WriterLogger
extends java.lang.Object
implements Logger

Provides an implementation of the Logger interface that sends output to the specified java.io.Writer.

Each log entry is formatted using the BasicLogFormatter.format(String level, String message, String loggerName) method.

Note that each logging level can be enabled independently in this implementation. All levels are enabled by default.

isErrorEnabled

public boolean isErrorEnabled()

Description copied from interface: Logger

Indicates whether logging is enabled at the ERROR level.

Specified by:

isErrorEnabled in interface Logger

Returns:

true if logging is enabled at the ERROR level, otherwise false.

setErrorEnabled

public void setErrorEnabled(boolean errorEnabled)

Sets whether logging is enabled at the ERROR level.

Parameters:

errorEnabled - determines whether logging is enabled at the ERROR level.

isWarnEnabled

public boolean isWarnEnabled()

Description copied from interface: Logger

Indicates whether logging is enabled at the WARN level.

Specified by:

isWarnEnabled in interface Logger

Returns:

true if logging is enabled at the WARN level, otherwise false.

setWarnEnabled

public void setWarnEnabled(boolean warnEnabled)

Returns:

true if logging is enabled at the INFO level, otherwise false.

setInfoEnabled

public void setInfoEnabled(boolean infoEnabled)

Parameters:

infoEnabled - determines whether logging is enabled at the INFO level.

isDebugEnabled

public boolean isDebugEnabled()

Description copied from interface: Logger

Indicates whether logging is enabled at the DEBUG level.

true if logging is enabled at the DEBUG level, otherwise false.

setDebugEnabled

public void setDebugEnabled(boolean debugEnabled)

Sets whether logging is enabled at the DEBUG level.

Parameters:

debugEnabled - determines whether logging is enabled at the DEBUG level.

log

protected void log(java.lang.String level,
                   java.lang.String message)

Logs the specified message at the specified level.

This method is called internally by the error(String), warn(String), info(String) and debug(String) methods, with the level argument set to the text "ERROR", "WARN", "INFO", or "DEBUG" respectively.

The default implementation of this method sends the the output of BasicLogFormatter.format(level,message,getName()) to the Writer specified in the class constructor, and then flushes it.

Overriding this method in a subclass provides a convenient means of logging to a Writer using a different format.

Parameters:

level - a string representing the level of the log message.

message - the message to log.
