Obtaining current assignee of a process instance

Question

Is there an API call that will tell me whether a process instance is currently assigned to a participant? I've tried using ProcessInstance.participant but this returns the 'active' participant, which, if called from an automatic activity returns "Automatic Handler." Clearly not the actual assignee.
A call that returns a simple boolean would be great. A call that returns the assignee's Participant object would be even better.
Thanks for any help.

I am copying a piece of studio docs.
this is the documentation for "participant.sticky" property
If set to true, the participant.next is set as the preferred participant. Each time the instance moves to an activity and the participant.next is enabled to work with it (belongs to the role where the activity is), the instance is submitted to the participant.next work queue. In the Split and SplitN activities, all generated copies maintain the participant.sticky value from the original instance. In the SplitN method you can change its value. Note: if the participant.next is changed during the process, be sure that participant.sticky is reset unless the new participant.next is considered the preferred participant.
and this is for "participant.next"
The participant to which the instance will be sent next. Note: If the instance is grabbed, the participant.next is cleared. If the instance is sent BACK or SKIP from an Exception flow or from an Interruption, the only way to reset the participant.next is using the Unselect method from the Participant component. See Participant component documentation for further information.
