Boundary Type (Core Services)

Defines the behavior of data retrieval at the end points of a specified time range. The following values are accepted:

• Inside

  Specifies to return the recorded values on the inside of the requested time range as the first and last values. When used as the boundary type for a sync time, all returned values are guaranteed to be within the specified time range.

• Outside

  Specifies to return the recorded values on the outside of the requested time range as the first and last values. When used as the boundary type for a sync time, the returned values can be outside the specified time range by no more than one interval. For more details, see the Sync Time help topic.

• Interpolated

  Specifies to create an interpolated value at the end points of the requested time range if a recorded value does not exist at that time. This boundary type is not supported for sync times.
