Interface Logger

All Superinterfaces:

org.apache.ojb.broker.util.configuration.Configurable, java.io.Serializable

All Known Implementing Classes:

CommonsLoggerImpl, Log4jLoggerImpl, PoorMansLoggerImpl, StringBufferLoggerImpl

public interface Logger
extends java.io.Serializable, org.apache.ojb.broker.util.configuration.Configurable

this interface defines the behaviour of a logging mechanism. This API corresponds closely to the LOG4J Category Api. By using this interface OJB remains free from Logger-Implementation specific code.
