Class Logger

java.lang.Object

NearOCR.Logger

public abstract class Logger
extends java.lang.Object

The logger is a client-agnostic way of reporting events and progress from the OCR manager to the interface. It notifies whatever is listening of time, severity and custom details of each event, which may be a success, failure or information.

Listeners must implement NearOCR.MessageListener and add themselves as message listeners in order to receive logger events
