Interface ActivityConfiguration

All Known Implementing Classes:

AddAndIndexFileActivityConfiguration, PhysicalSchemaFileActivityConfiguration

public interface ActivityConfiguration

An ActivityConfiguration object encapsulates configuration information relating to a single Activity. It is optional whether or not an Activity makes use of an ActivityConfiguration object. If so, the Activity must implement the ActivityConfigurationCreator interface, which defines a factory method responsible for creating the appropriate ActivityConfiguration object.

As well as implementing the initialise method, an ActivityConfiguration implementation should provide appropriate methods for accessing the configuration information in a convenient manner. These will be used by the Activity that is being configured.
