Interface ILogger

All Known Implementing Classes:

NopLogger

public interface ILogger

Logger interface that is used by the API to log messages. It separates the core API from any specific logger implementation.

Typical usage pattern:

 import org.snf4j.core.logger.ILogger;
 import org.snf4j.core.logger.LoggerFactory;
 
 class Foo {
     private ILogger log = LoggerFactory.getLogger(Foo.class);
     
     Foo(int arg1, Object arg2) {
         log.debug("Foo created with args: {} {}", arg1, arg2);
     }
 }
