Method Detail

newLogger

protected org.slf4j.Logger newLogger(java.lang.String name,
                                     LoggerContext context)

Description copied from class: AbstractLoggerAdapter

Creates a new named logger for a given LoggerContext.

Specified by:

newLogger in class AbstractLoggerAdapter<org.slf4j.Logger>

Parameters:

name - the name of the logger to create

context - the LoggerContext this logger will be associated with

Returns:

the new named logger

getContext

protected LoggerContext getContext()

Description copied from class: AbstractLoggerAdapter

Gets the LoggerContext that should be used to look up or create loggers. This is similar in spirit to the ContextSelector class in log4j-core. However, implementations can rely on their own framework's separation of contexts instead (or simply use a singleton).

Specified by:

getContext in class AbstractLoggerAdapter<org.slf4j.Logger>

Returns:

the LoggerContext to be used for lookup and creation purposes

LogManager.getContext(ClassLoader, boolean), LogManager.getContext(String, boolean)

getMarkerFactory

Log4jMarkerFactory getMarkerFactory()

validateContext

private LoggerContext validateContext(LoggerContext context)
