Field Details

LEVEL_NONE

public static final int LEVEL_NONE

No logging at all.

See Also:

• Constant Field Values

LEVEL_ERROR

public static final int LEVEL_ERROR

Critical errors. The application may no longer work correctly.

See Also:

• Constant Field Values

LEVEL_WARN

public static final int LEVEL_WARN

Important warnings. The application will continue to work correctly.

See Also:

• Constant Field Values

LEVEL_INFO

public static final int LEVEL_INFO

Informative messages. Typically used for deployment.

See Also:

• Constant Field Values

LEVEL_DEBUG

public static final int LEVEL_DEBUG

Debug messages. This level is useful during development.

See Also:

• Constant Field Values

LEVEL_TRACE

public static final int LEVEL_TRACE

Trace messages. A lot of information is logged, so this level is usually only needed when debugging a problem.

See Also:

• Constant Field Values

level

private static int level

The level of messages that will be logged. Compiling this and the booleans below as "final" will cause the compiler to remove all "if (Log.info) ..." type statements below the set level.

ERROR

public static boolean ERROR

True when the ERROR level will be logged.

WARN

public static boolean WARN

True when the WARN level will be logged.

INFO

public static boolean INFO

True when the INFO level will be logged.

DEBUG

public static boolean DEBUG

True when the DEBUG level will be logged.

TRACE

public static boolean TRACE

True when the TRACE level will be logged.

logger

private static Log.Logger logger
