Class ServiceBlockCommander

  extended by com.codemonster.surinam.mgmt.ServiceBlockCommander

public class ServiceBlockCommander
extends Object

This is a wrapper for a Service Block that will accept Action (command) Sequences and apply them to the given Service Block. This arrangement keeps the command layer separate so that the API can exist independently without knowledge of a command wrapper. This separation would also make it easier to create new wrappers and or extend existing wrappers without altering the core API.

public ServiceBlockCommander(ServiceBlock serviceBlock)
Here we require the commander to be handed the ServiceBlock that it will wrap. This is as much for convenience as to stress the importance of the block to the wrapper.

Method Detail


public void apply(ActionSequence actions)
           throws IllegalAccessException,
Here, we iterate through the list, executing each action. Since this is effectively the same as what we can do programmatically, we will need to be prepared for all the failures that could happen in the hard-coded programmed approach. It is possible that if you have an Action Document or Sequence, that represents the current state of the service block an attempt to apply
