Class Logging

java.lang.Object

com.bloomberglp.blpapi.Logging

public class Logging
extends Object

Provides a way to register a call back for logging

The call back is provided as an interface that needs to be implemented. The method Logging.Callback.onMessage(long, Level, Datetime, String, String) is called when a message that needs logging is available. Callback is only called for messages that have 'level' higher than or equal to the 'defaultThresholdLevel'. There can be only one callback that can be registered and if another callback is registered it will replace the previous one.

 Logging.Callback cb = new Logging.Callback() {
     public void onMessage(
             long threadId,
             Level level,
             Datetime dateTime,
             String loggerName,
             String message) {
             // Do some processing
     }
 };
 Logging.registerCallback(cb, Level.WARNING);
