public interface Action

A marker interface for all actions that can be applied to a Delta table. Each action represents a single change to the state of a Delta table.

You can use the following code to extract the concrete type of an Action.

   List<Action> actions = ...
   actions.forEach(x -> {
       if (x instanceof AddFile) {
          AddFile addFile = (AddFile) x;
          ...
       } else if (x instanceof AddCDCFile) {
          AddCDCFile addCDCFile = (AddCDCFile)x;
          ...
       } else if ...
   });
