#File Listener

You can use this library to create a file listener that reads and caches the file contents, monitoring the file mtime to reload contents on demand.

#Examples

Reading a JSON file

With a Map:

FileMonitor<Map> monitor = FileMonitorFactory.createFileMonitor(new File("someFile.json"), Map.class);
Map contents = monitor.get();  

With your custom type:

FileMonitor<CustomPOJO> monitor = FileMonitorFactory.createFileMonitor(new File("someFile.json"), CustomPOJO.class);
CustomPOJO contents = monitor.get();  

Make your own reader

public class CountingFileReader<T> extends DefaultFileReader<T> {

  private int count = 0;

  public CountingFileReader(Class klass) {
    super(klass);
  }

  @Override
  public T read(File file) throws IOException {
    count++;
    return super.read(file);
  }

  public int getCount() {
    return count;
  }
}

CountingFileReader<Map> reader = new CountingFileReader<>(MyPOJO.class);
FileMonitor<Map> monitor = FileMonitorFactory.createFileMonitor(new File("someFile.dat"), reader);
