# Interface IncrementalCommand

public interface IncrementalCommand
An `IncrementalCommand` is a command that is broken into one or more substeps, each substep brings the whole command nearer to completion. The command is complete when `execute()` returns `false`.

    public class IncrementalCommandExample implements EntryPoint {

      public void onModuleLoad() {
        final Label label = new Label();

        DeferredCommand.addCommand(new IncrementalCommand() {
          private int index = 0;

          protected static final int COUNT = 10;

          public boolean execute() {
            label.setText("IncrementalCommand - index " + Integer.toString(index));

            return ++index < COUNT;
          }
        });
      }
    }
