org.apache.wsrp4j.log .Logger

All known Subclasses:   org.apache.wsrp4j.log .LoggerImpl,
Logger
public interface Logger (Code)
Logger defines the methods which are used to create logging messages.
Logging levels are:

ERROR
A serious failure in the execution of the application
WARN
An abnormal condition has been detected. The user may have to take action, but the running code is able to handle this condition without ultimately failing.
INFO
A condition that is worth noting but that does not require the user to perform an action.
TRACE_LOW
A low-detail trace message.
TRACE_MEDIUM
A medium-detail trace message.
TRACE_HIGH
A high-detail trace message.

Plain-text messages can be logged through the text(...) methods. These messages are generally hard-coded into the application.
These methods should only be used for logging trace data.
In addition, the following specialized methods are available to log trace information. Each of these trace methods is a convenience to the application programmer:

entry
Logs entry into a method.
exit
Logs exit from a method.
stackTrace
Logs the call stack.

For performance reasons the method isLogging(int logLevel) should be used to check if a given logging level is written at all to the output. The method should be used for the log message level entries, but is absolutely required to be called for trace messages to avoid unnecessary round-trips and object creation.

Field Summary
final public static int ERROR
     Defines an error message.
Use this type to inform the user of a serious failure in the execution of the application.
final public static int INFO
     Defines an informational message.
Use this type to indicate conditions that are worth noting but that do not require a user to take any precautions or perform an action.
final public static int TRACE_HIGH
     Defines a high-detail trace message.
final public static int TRACE_LOW
     Defines a low-detail trace message.
final public static int TRACE_MEDIUM
     Defines a medium-detail trace message.
final public static int WARN
     Defines a warning message.
Use this type to inform a user that an abnormal condition has been detected.

Field Detail
ERROR
final public static int ERROR(Code)
Defines an error message.
Use this type to inform the user of a serious failure in the execution of the application.

INFO
final public static int INFO(Code)
Defines an informational message.
Use this type to indicate conditions that are worth noting but that do not require a user to take any precautions or perform an action. Do not use this log level for repeating events.
An informational message is less severe than a warning message.

TRACE_HIGH
final public static int TRACE_HIGH(Code)
Defines a high-detail trace message.

TRACE_LOW
final public static int TRACE_LOW(Code)
Defines a low-detail trace message.

TRACE_MEDIUM
final public static int TRACE_MEDIUM(Code)
Defines a medium-detail trace message.

WARN
final public static int WARN(Code)
Defines a warning message.
Use this type to inform a user that an abnormal condition has been detected. The user may have to take action, but the running code is able to handle this condition without ultimately failing.
A warning message is less severe than an error message.
