Constructor Detail

FmrcImpl

public FmrcImpl(String filename)
         throws IOException

Throws:

IOException

FmrcImpl

public FmrcImpl(NetcdfDataset ncd)
         throws IOException

Throws:

IOException

Method Detail

sync

public boolean sync()
             throws IOException

Check if file has changed, and reread metadata if needed. All previous object references (variables, dimensions, etc) may become invalid - you must re-obtain.

Specified by:

sync in interface ForecastModelRunCollection

Returns:

true if file was changed.

Throws:

IOException

getGridDataset

public GridDataset getGridDataset()

Description copied from interface: ForecastModelRunCollection

Get the underlying GridDataset.

Specified by:

getGridDataset in interface ForecastModelRunCollection

Returns:

the GridDataset containing that data.

close

public void close()
           throws IOException

Specified by:

close in interface ForecastModelRunCollection

Throws:

IOException

getRunDates

public List<Date> getRunDates()

Description copied from interface: ForecastModelRunCollection

Get the list of possible run dates, to be used in getRunTimeDataset().

Specified by:

getRunDates in interface ForecastModelRunCollection

Returns:

List of Date

getRunTimeDataset

public NetcdfDataset getRunTimeDataset(Date wantRuntime)
                                throws IOException

Description copied from interface: ForecastModelRunCollection

Get a NetcdfDataset that has all the data for a model run. The time coordinate will be the forecast time. The runtime will be a global attribute called "_runTime" containing an ISO date string.

Specified by:

getRunTimeDataset in interface ForecastModelRunCollection

Parameters:

wantRuntime - names the run

Returns:

the NetcdfDataset for that data.

Throws:

IOException - on read error

getForecastDates

public List<Date> getForecastDates()

Description copied from interface: ForecastModelRunCollection

Get the list of possible forecast dates, to be used in getForecastTimeDataset().

Specified by:

getForecastDates in interface ForecastModelRunCollection

Returns:

List of Date

getForecastTimeDataset

public NetcdfDataset getForecastTimeDataset(Date forecastTime)
                                     throws IOException

Description copied from interface: ForecastModelRunCollection

Get a NetcdfDataset that has all the data for a fixed forecast time, across model runs. The time coordinate will be the run time. The forecast time will be a global attribute called "_forecastTime" containing an ISO date string.

Specified by:

getForecastTimeDataset in interface ForecastModelRunCollection

Parameters:

forecastTime - the forecast time to fix.

Returns:

the NetcdfDataset for that data.

Throws:

IOException - on read error

getForecastOffsets

public List<Double> getForecastOffsets()

Description copied from interface: ForecastModelRunCollection

Get the list of possible forecast offsets, to be used in getForecastOffsetDataset().

Specified by:

getForecastOffsets in interface ForecastModelRunCollection

Returns:

List of Double

getForecastOffsetDataset

public NetcdfDataset getForecastOffsetDataset(double hours)
                                       throws IOException

Description copied from interface: ForecastModelRunCollection

Get a NetcdfDataset that has all the data for a fixed forecast offset, across model runs. The time coordinate will be the forecast time. There will be a String-valued variable called "RunTime(time)" containing an array of ISO date strings.

Specified by:

getForecastOffsetDataset in interface ForecastModelRunCollection

Parameters:

hours - the forecast offset time to fix, in hours.

Returns:

the NetcdfDataset containing that data.

Throws:

IOException - on read error

getBestTimeSeries

Returns:

the NetcdfDataset containing that data.

Throws:

IOException - on read error
