close

public void close()

Description copied from class: Logger

Perform whatever cleanup is required of the underlying object..

Resource.close()

fatal

public void fatal(java.lang.String message)

Description copied from class: Logger

Log a message w/ a fatal priority. Fatal messages are usually not recoverable & will precede an application shutdown. Actual support for this priority is log implementation specific, but should be available in most packages. (e.g. Log4J, JDK1.4)

Specified by:

fatal in class Logger

Parameters:

message -

See Also:

Logger.fatal(String)

fatal

public void fatal(java.lang.String message,
                  java.lang.Throwable t)

Description copied from class: Logger

Log a message w/ a fatal priority. Fatal messages are usually not recoverable & will precede an application shutdown. Actual support for this priority is log implementation specific, but should be available in most packages. (e.g. Log4J, JDK1.4)

Specified by:

fatal in class Logger

Parameters:

message -

t -

See Also:

com.rhi.architecture.logging.Logger#fatal(String, Exception)

error

public void error(java.lang.String message)

Description copied from class: Logger

Log a message w/ an error priority. Errors are used for problems found during processing that are not fatal. Actual support for this priority is log implementation specific, but should be available in most packages. (e.g. Log4J, JDK1.4)

Specified by:

error in class Logger

Parameters:

message -

Logger.error(String)

error

public void error(java.lang.String message,
                  java.lang.Throwable t)

Description copied from class: Logger

Log a message w/ an error priority. Errors are used for problems found during processing that are not fatal. Actual support for this priority is log implementation specific, but should be available in most packages. (e.g. Log4J, JDK1.4)

Specified by:

error in class Logger

Parameters:

message -

t -

See Also:

com.rhi.architecture.logging.Logger#error(String, Exception)

warning

public void warning(java.lang.String message)

Description copied from class: Logger

Log a message w/ a warning priority. Warnings are useful for messages that signal an error in the future if not corrected. (e.g. low disk space) or potential errors that may not be a problem depending on context that the logging component does not have. Actual support for this priority is log implementation specific, but should be available in most packages. (e.g. Log4J, JDK1.4)

Specified by:

warning in class Logger

Parameters:

message -

See Also:

Logger.warning(String)

isWarningEnabled

public boolean isWarningEnabled()

Description copied from class: Logger

Check whether this category is enabled for the WARNING Level.

Specified by:

isWarningEnabled in class Logger

Returns:

boolean

See Also:

Logger.isWarningEnabled()

info

public void info(java.lang.String message)

Description copied from class: Logger

Log a message w/ an informational priority. Informational messages will include things like operational statistics, which are nice to have, but don't signal an error of any kind in the application. The number of informational messages used in a process should be very low. Actual support for this priority is log implementation specific, but should be available in most packages. (e.g. Log4J, JDK1.4)

Specified by:

info in class Logger

Parameters:

message -

See Also:

Logger.info(String)

isInfoEnabled

public boolean isInfoEnabled()

Description copied from class: Logger

Check whether this category is enabled for the INFO Level.

Specified by:

isInfoEnabled in class Logger

Returns:

boolean

See Also:

Logger.isInfoEnabled()

debug

public void debug(java.lang.String message)

Description copied from class: Logger

Log a message w/ a debug priority. Debug messages are normally be disabled in production environments, but can be quite useful during development.

Specified by:

debug in class Logger

Parameters:

message -

See Also:

Logger.debug(String)

isDebugEnabled

public boolean isDebugEnabled()

Description copied from class: Logger

Check whether this category is enabled for the DEBUG Level.

Specified by:

isDebugEnabled in class Logger

Returns:

boolean

See Also:

Logger.isDebugEnabled()

trace

public void trace(java.lang.String message)

Description copied from class: Logger

Log a message w/ a trace priority. Trace messages are the most granular and will normally be disabled in production environments, but can be quite useful during development. If the underlying logging implementation does not support this level, trace messages should be logged w/ the most verbose logging level available.

Specified by:

trace in class Logger

Parameters:

message -

See Also:

Logger.trace(String)

isTraceEnabled

public boolean isTraceEnabled()

Description copied from class: Logger

Check whether this category is enabled for the TRACE Level.

Specified by:

isTraceEnabled in class Logger

Returns:

boolean

See Also:

Logger.isTraceEnabled()
