All Implemented Interfaces:

LineListener

Direct Known Subclasses:

AsListsLineListener

public class BasicLineListener

extends CustomLineListener

Simple implementation of LineListener that stores loaded data lines as a List of String[] arrays.

The easiest way to get your CSV data in this format is to use the CsvManager.load method.

This LineListener is a good one to use as a template for your own custom LineListeners.

BasicLineListener is designed to be subclassed. You can change the default implementation by calling the CsvManagerStore.setBasicLineListenerClass method, and providing a subclass of BasicLineListener. CsvManagerStore can be accessed using CsvManager.getCsvManagerStore().
