                                  Formatter errlog)

Identify ragged array representations for single nests (station, profile, trajectory)

Parameters:

ds - in this dataset

info - put info here

instanceDim - the instance dimension, null if not known yet

sampleDim - the sample dimension, null if not known yet

errlog - error go here

Returns:

true if ragged array representations is found; side effect: set (info.ragged_rowSize, info.parentStruct) or (info.ragged_parentIndex, info.childStruct)

identifyDoubleRaggeds

protected boolean identifyDoubleRaggeds(NetcdfDataset ds,
                                        CFpointObs.EncodingInfo info,
                                        Formatter errlog)

Identify ragged array representations for double nests (timeSeries profile, timeSeries trajectory)

This uses the contiguous ragged array representation for each profile (9.5.43.3), and the indexed ragged array representation to organise the profiles into time series (9.3.54). The canonical use case is when writing real-time data streams that contain profiles from many stations, arriving randomly, with the data for each entire profile written all at once.

Parameters:

ds - in this dataset

info - put info here

errlog - error go here

Returns:

EncodingInfo if ragged array representations is found
