## Interface TaskInstanceService

- All Superinterfaces:
    `org.kie.api.runtime.CommandExecutor`

      public interface TaskInstanceService
      extends org.kie.api.runtime.CommandExecutor

  The Task Instance Service is in charge of handling all the actions required to interact with a Task Instance. All the operations described in the WS-HT specification related with the Task Lifecycle are implemented here.
