Term: ProbeUpdateSpecification

The time at which a Probe runs for the second and subsequent times is determined by a ProbeUpdateSpecification associated with the data source.

InfoGrid provides several types of ProbeUpdateSpecification, including:

  • one-time update: run the Probe once, but never again
  • periodic update: run the Probe at equal time intervals
  • adaptively periodic update: run the Probe at increasing time intervals if the information found is the same; reset to a faster schedule once the information found changes.

The Probe Framework associates the ProbeUpdateSpecification with the data source by blessing, above and beyond what the Probe implementation may do, the ShadowMeshBase's HomeObject with the correct subtype of ProbeUpdateSpecification.
