All Known Subinterfaces:

Logger

public interface Logger

The Logger interface defines application logging functions. A Logger can be obtained from a JwsContext or ControlContext instance. Logging may be enabled at one of four levels: "debug" (lowest level, results in highest volume of output), "info", "warn" or "error" (highest level, results in least output). Messages emitted below the current logging level are not logged.

Method Summary

void	debug(String message) Emit a "debug" level message.
void	debug(String message, Throwable throwable) Emit a "debug" level message with an associated Throwable.
void	error(String message) Emit a "error" level message.
void	error(String message, Throwable throwable) Emit a "error" level message with an associated Throwable.
void	info(String message) Emit a "info" level message.
void	info(String message, Throwable throwable) Emit a "info" level message with an associated Throwable.
boolean	isDebugEnabled() returns true if "debug" level logging is enabled.
boolean	isErrorEnabled() returns true if "error" level logging is enabled.
boolean	isInfoEnabled() returns true if "info" level logging is enabled.
boolean	isWarnEnabled() returns true if "warn" level logging is enabled.
void	warn(String message) Emit a "warn" level message.
void	warn(String message, Throwable throwable) Emit a "warn" level message with an associated Throwable.

warn

void warn(String message)

Emit a "warn" level message.

warn

void warn(String message,
          Throwable throwable)

Emit a "warn" level message with an associated Throwable.

Parameters:

message - the message to write to the log.

throwable - the Throwable (typically an Exception) to write to the log.

error

Parameters:

message - the message to write to the log.

throwable - the Throwable (typically an Exception) to write to the log.

isDebugEnabled

boolean isDebugEnabled()

returns true if "debug" level logging is enabled. "debug" level is only enabled if the current logging level is "debug".

isInfoEnabled

boolean isInfoEnabled()

returns true if "info" level logging is enabled. "info" level is enabled if the current logging level is "info" or "debug".

isWarnEnabled

boolean isWarnEnabled()

returns true if "warn" level logging is enabled. "warn" level is enabled if the current logging level is "warn", "info" or "debug".

isErrorEnabled

boolean isErrorEnabled()

returns true if "error" level logging is enabled. "error" level is enabled if the current logging level is "error", "warn", "info" or "debug".
