MonologLoggerFactory

public MonologLoggerFactory()
Method Detail

defineDefaultLevels

protected void defineDefaultLevels()
It initializes the default monolog level:


configure

public void configure(java.util.Properties prop)
               throws java.lang.Exception
This method permits to configure the factory.

Specified by:
configure in interface MonologFactory
Parameters:
prop - contains properties which describes the way to configure. In particular three properties could be used:
  • LOG_CONFIGURATION_TYPE
  • LOG_CONFIGURATION_FILE
  • LOG_CONFIGURATION_FILE_USE_CLASSPATH
    • Throws:
      java.lang.Exception

getLoggers

public Logger[] getLoggers()
Description copied from interface: LoggerFactory
It retrieves a list of all loggers.

Specified by:
getLoggers in interface LoggerFactory

getLogger

public Logger getLogger(java.lang.String key)
Description copied from interface: LoggerFactory
This method permits to fetch a Logger. If the Logger described by the parameters does not exist, then the LoggerFactory must return a new instance of Logger. The key parameter is a description of the expected Logger. In simple cases, the key is the initial topic of the Logger.

Specified by:
getLogger in interface LoggerFactory

getLogger

public Logger getLogger(java.lang.String key,
                        java.lang.String rbn)
Description copied from interface: LoggerFactory
This method permits to fetch a Logger. If the Logger described by the parameters does not exist, then the LoggerFactory must return a new instance of Logger. The key parameter is a description of the expected Logger. In simple cases, the key is the initial topic of the Logger. The resourceBundleName parameter allows specifying the name of a resource bundle in order to internationalise the logging.

Specified by:
getLogger in interface LoggerFactory

getResourceBundleName

public java.lang.String getResourceBundleName()
Description copied from interface: LoggerFactory
Accessors to a resource bundle name associated to a LoggerFactory.

Specified by:
getResourceBundleName in interface LoggerFactory

setResourceBundleName

public void setResourceBundleName(java.lang.String rbn)
Description copied from interface: LoggerFactory
Accessors to a resource bundle name associated to a LoggerFactory.

Specified by:
setResourceBundleName in interface LoggerFactory

defineLevel

public Level defineLevel(java.lang.String name,
                         int value)
Description copied from interface: LevelFactory
It defines a new Level with a name and an integer value.

Specified by:
defineLevel in interface LevelFactory
Parameters:
name - is the name of the new level
value - is the integer value of the new level
Returns:
a Level instance or a null value if It exists a Level with the same name but with another integer value.
