IAdapterSetTemporalConstraint Method

Defines a temporal processing constraint for the adapter.

Namespace: GSF.TimeSeries.Adapters
Assembly: GSF.TimeSeries (in GSF.TimeSeries.dll) Version: 2.4.218-beta
Syntax
void SetTemporalConstraint(
	string startTime,
	string stopTime,
	string constraintParameters
)

Parameters

startTime  String
Defines a relative or exact start time for the temporal constraint.
stopTime  String
Defines a relative or exact stop time for the temporal constraint.
constraintParameters  String
Defines any temporal parameters related to the constraint.
Remarks

This method defines a temporal processing constraint for an adapter, i.e., the start and stop time over which an adapter will process data. Actual implementation of the constraint will be adapter specific. Implementations should be able to dynamically handle multiple calls to this function with new constraints. Passing in null for the startTime and stopTime should cancel the temporal constraint and return the adapter to standard / real-time operation.

The startTime and stopTime parameters can be specified in one of the following formats:
