[slf4j-dev] addChildLogger method

[Ceki Gülcü]

If POJOs can be injected Logger objects, why can't they be injected
LoggerFactory objects?

Let MyClass be written:

import org.slf4j.LoggerFactorAdapter;

  public class MyClass  {
       private MyOtherClass m_other1;
       private MyOtherClass m_other2;

        public MyClass( LoggerFactorAdapter loggerFactory )
        {
            Logger logger = loggerFactory.getLogger(MyClass.class);
            m_other1 = new MyOtherClass( loggerFactory, 10 );
            m_other2 = new MyOtherClass( loggerFactory, 20 );
        }
    }
