public class LogLevel

extends java.lang.Object

LogLevels are required to filter the log messages based on their severity. When a
particular level is specified, the messages with levels lower than or equal to the
given value will be recorded. This can be configured in the source from where LogConfigReader
would read the configuration details. In this framework, by default, the LogConfigReader
reads the details from a file. So, this can be configured in the file logging.xml
through the parameter LogLevel. This parameter enables you to receive the messages
of required severity alone.

Categories of LogLevels :

Following are the three categories of LogLevel.

• Level1
• Level2
• Level3

Level1 - Indicates very important messages (i.e) Messages of crucial importance
Level2 - Indicates messages of intermediate importance (i.e) Messages that might
cause problems.
Level3 - Indicates normal messages. (i.e) Messages not so important. Messages of
informational type.

Note : If Level 3 is chosen, all messages belonging to Level 1, 2 and 3 will be written.

Apart from the above 3 levels, there is a fourth level with value 0. This level disables
Logging.

Setting logLevel

The LogLevel can be specified in the source from where LogConfigReader would read the configuration details. In this framework, by default LogConfigReader reads the details from the file logging.xml. So, you can set the LogLevel in that file.

Alternatively, LogLevel can be dynamically set or changed by calling the method setLogLevel(int i) in Logger. Also, you can have different LogLevels for different modules. To illustrate how different LogLevels for different modules can be set, an example has been provided below. In this example, LogLevels have been set for two different modules for receiving server output messages.
