alocateMeasurements

public long alocateMeasurements(MeasurementsInfo measurement,
                                int sampleTimeMillis)

Description copied from interface: MeasurementStore

Make any allocations necessary for the following measurements.

Specified by:

alocateMeasurements in interface MeasurementStore

Parameters:

measurement - - the information about the measurement(s)

sampleTimeMillis - - the expected sample time. (interval between the stored measurements).

Returns:

- the id of the measurementInfo table.
