Class LogbackLoggingSupport

java.lang.Object

org.apache.cassandra.utils.logging.LogbackLoggingSupport

All Implemented Interfaces:

LoggingSupport

public class LogbackLoggingSupport
extends java.lang.Object
implements LoggingSupport

Encapsulates all logback-specific implementations in a central place. Generally, the Cassandra code-base should be logging-backend agnostic and only use slf4j-api. This class MUST NOT be used directly, but only via LoggingSupportFactory which dynamically loads and instantiates an appropriate implementation according to the used slf4j binding.
