RecordDatasetHelper

public RecordDatasetHelper(NetcdfDataset ncfile,
                           java.lang.String obsTimeVName,
                           java.lang.String nomTimeVName,

                           java.util.Formatter errBuffer)

Constructor.

Parameters:

ncfile - the netccdf file

typedDataVariables - list of data variables; all record variables will be added to this list, except . You can remove extra

obsTimeVName - observation time variable name (required)

nomTimeVName - nominal time variable name (may be null)

Throws:

java.lang.IllegalArgumentException - if ncfile has no unlimited dimension and recDimName is null.

Method Detail

setStationInfo

public void setStationInfo(java.lang.String stnIdVName,
                           java.lang.String stnDescVName,

                           StationHelper stationHelper)

Set extra information used by station obs datasets. Use stnIdVName or stnIndexVName.

Parameters:

stnIdVName - the obs variable that is used to find the station in the stnHash; may be type int or a String (char).

stnDescVName - optional station var containing station description
