Using a Logger Object
Once you retrieve a logger object from LogBox, you are ready to start sending messages. We already covered how to dynamically add/remove/list/check appenders from a logger, so let's look at the other methods we have available:
Instance Members
Every logger has access to the following public variables:
Utility Methods
Logging Methods
As you can probably tell, all logging methods take in a message string an a second argument called extraInfo
. This extraInfo
argument can be anything from a string, a structure, a query or whatever. This way you can send in a complex structure that the appenders will serialize into message form or log into the appropriate channel. Thus, extraInfo
can be very handy when you are building your own custom appenders.
I hope that by now you understand the basics of loggers and how easy it is to use them.
