newLogger
protected org.slf4j.Logger newLogger(java.lang.String name, LoggerContext context)
Description copied from class:AbstractLoggerAdapter
Creates a new named logger for a givenLoggerContext
.- Specified by:

- Parameters:
name
- the name of the logger to createcontext
- the LoggerContext this logger will be associated with- Returns:
- the new named logger

getContext
protected LoggerContext getContext()
Description copied from class:AbstractLoggerAdapter
Gets theLoggerContext
that should be used to look up or create loggers. This is similar in spirit to theContextSelector
class inlog4j-core
. However, implementations can rely on their own framework's separation of contexts instead (or simply use a singleton).- Specified by:
getContext
in classAbstractLoggerAdapter<org.slf4j.Logger>
- Returns:
- the LoggerContext to be used for lookup and creation purposes
- See Also:
LogManager.getContext(ClassLoader, boolean)
,LogManager.getContext(String, boolean)
