 Logger logger)

Method Details

setLevel

public void setLevel(Level level)

Sets the level for this logger.

Care is taken to use reflection to access logback-classic Level and Logger classes (to avoid hard runtime dependency when only the sl4j api is provided at runtime).

Of logback-classic is unavailable level cannot be changed programmatically.

Specified by:

setLevel in class LoggerAdapter

Parameters:

level - Standard logging level used to configure logger

getLevel

public Level getLevel()

Description copied from class: LoggerAdapter

Returns the level for this logger. Subclasses shall get this level from the external logging framework.

Specified by:

getLevel in class LoggerAdapter

isLoggable

public boolean isLoggable(Level level)

Description copied from class: LoggerAdapter

Returns true if the specified level is loggable.

Implementation tip
Given that Level.intValue() for all predefined levels are documented in the Level specification and are multiple of 100, given that integer divisions are rounded toward zero and given rule documented in this class javadoc, then logging levels can be efficiently mapped to predefined levels using switch statements as below. This statement has good chances to be compiled to the tableswitch bytecode rather than lookupswitch (see Compiling Switches in The Java Virtual Machine Specification).

Specified by:

isLoggable in class LoggerAdapter

log

public void log(Level level,
 String message)

Description copied from class: LoggerAdapter

Logs a record at the specified level. The default implementation delegates to one of the severe, warning, info, config, fine, finer or finest methods according the supplied level.

Overrides:

log in class LoggerAdapter

severe

Description copied from class: LoggerAdapter

Logs a SEVERE message.

Specified by:

severe in class LoggerAdapter

warning

public void warning(String message)

Description copied from class: LoggerAdapter

Logs a WARNING message.

Specified by:

warning in class LoggerAdapter

info

public void info(String message)

Description copied from class: LoggerAdapter

Logs an INFO message.

Specified by:

info in class LoggerAdapter

config

public void config(String message)

Description copied from class: LoggerAdapter
