Interface JavaTaskIterator

public interface JavaTaskIterator

When your customized JavaTask implements this interface, it makes loop on the hasNext(DataCollection) method.

While the invocation of the method hasNext(DataCollection) returns true, the JavaTask.execute(DataCollection) is invoked with the same data collection.

Note

You cannot extend your customized Java task with both this JavaTaskIterator interface and the JavaTaskInitializable interface.
