Examples of BaseChain

com.level3.meanwhile.base.BaseChain
Encapsulates a Task that has dependent Tasks that are intended to be run upon successful completion of this task
This abstract Class extends BaseTask (inheriting its TaskStatus mechanism) and implements Chain, providing a basic implementation of Chain functionality.
Clients must provide a concrete implementation of the execute() method.
Usually, a client would extend this class, but you may at a minimum create an Anonymous Inner Class, and @Override the execute() method as a quick-start.
The BaseChain class implements the following behavior:
- {@code onCancel()} - cancels all chained tasks
- {@code onFailure()} - cancels all chained tasks
- {@code onSubmit()} - calls onSubmit() of all chained tasks
