LogWriterI18n (GemFire Java API Documentation)

```
public interface LogWriterI18n
```
Defines methods available to clients that want to write a log message to their GemFire distributed system log file.
Instances of this interface can be obtained by calling DistributedSystem.getLogWriter().
For any logged message the log file will contain:
- The message's level.
- The time the message was logged.
- The id of the thread that logged the message.
- The message itself which can be a string and/or an exception including the exception's stack trace.
A message always has a level. Logging levels are ordered. Enabling logging at a given level also enables logging at higher levels. The higher the level the more important and urgent the message.
The levels, in descending order, are:
- severe (highest value) is a message level indicating a serious failure. In general severe messages should describe events that are of considerable importance and which will prevent normal program execution. They should be reasonably intelligible to end users and to information managers.
- error In general error messages should describe events that are of considerable importance but will not prevent normal program execution. They should be reasonably intelligible to end users and to information managers. They are weaker than severe and stronger than warning.
- warning is a message level indicating a potential problem. In general warning messages should describe events that will be of interest to end users or information managers, or which indicate potential problems.
- info is a message level for informational messages. Typically info messages should be reasonably significant and should make sense to end users and system administrators.
- config is a message level for static configuration messages. config messages are intended to provide a variety of static configuration information, to assist in debugging problems that may be associated with particular configurations.
- fine is a message level providing tracing information. In general the fine level should be used for information that will be broadly interesting to developers. This level is for the lowest volume, and most important, tracing messages.
- finer indicates a fairly detailed tracing message. Logging calls for entering, returning, or throwing an exception are traced at the finer level.
- finest (lowest value) indicates a highly detailed tracing message. In general the finest level should be used for the most voluminous detailed tracing messages.
For each level methods exist that will request a message, at that level, to be logged. These methods are all named after their level.
For each level a method exists that returns a boolean indicating if messages at that level will currently be logged. The names of these methods are of the form: levelEnabled.

    Parameters:
    sourceClass - Name of class that issued the logging request.
    sourceMethod - Name of the method that issued the logging request.
  - exiting
```
void exiting(String sourceClass,
           String sourceMethod)

    Log a method return.
    The logging is done using the finer level. The string message will start with "RETURN" and include the class and method names.
    
    Parameters:
    sourceClass - Name of class that issued the logging request.
    sourceMethod - Name of the method that issued the logging request.
  - throwing
```
void throwing(String sourceClass,
            String sourceMethod,

```
    Log throwing an exception.
    Use to log that a method is terminating by throwing an exception. The logging is done using the finer level.
    This is a convenience method that could be done instead by calling finer(String, Throwable). The string message will start with "THROW" and include the class and method names.
    
    Parameters:
    sourceClass - Name of class that issued the logging request.
    sourceMethod - Name of the method that issued the logging request.
    thrown - The Throwable that is being thrown.
  - finestEnabled

```
void finest(String msg)
```
    Writes a message to this writer. The message level is "finest".
  - finest
```
void finest(Throwable ex)
```
    Writes an exception to this writer. The exception level is "finest".
  - getHandler
```
Handler getHandler()
```
    Returns a 1.4 logging handler that can be used to direct application output to this GemFire logger using the standard JDK logger APIs. Each time this method is called it creates a new instance of a Handler so care should be taken to not call this method too often.
  - convertToLogWriter
```
LogWriter convertToLogWriter()
```
    A mechanism for accessing the abstraction layer used for a plain logger.
    
    Returns:
    LogWriter
