Class MLService

java.lang.Object

org.imixs.ml.workflow.MLService

All Implemented Interfaces:

Serializable

public class MLService
extends Object
implements Serializable

The MLService reacts on Processing events and updates the ml.status item. If no ml.status item exists, and ml.items is not empty, than the status is set to 'suggest'. If the status is 'suggest' and the current event is 'public' than the status is set to 'confirmed'

If the status was already confirmed, the workitem type is 'archive', than the ml status is set to 'training' and a eventLog entry is created to indicate that this workitem can be send to the training service. (Note: the training service can reject the workitem for training if the data is insufficient of quality)
