Constructor Detail

RadialDatasetSweepAdapter

public RadialDatasetSweepAdapter()

RadialDatasetSweepAdapter

public RadialDatasetSweepAdapter(NetcdfDataset ds)

Method Detail

addRadialVariable

protected abstract void addRadialVariable(NetcdfDataset ds,
                                          Variable var)

makeRadialVariable

protected abstract RadialDatasetSweep.RadialVariable makeRadialVariable(NetcdfDataset nds,
                                                                        VariableSimpleIF v,
                                                                        Variable v0)

setTimeUnits

protected abstract void setTimeUnits()
                              throws java.lang.Exception

Throws:

java.lang.Exception

getDetailInfo

public java.lang.String getDetailInfo()

Specified by:

getDetailInfo in interface TypedDataset

Overrides:

getDetailInfo in class TypedDatasetImpl

Returns:

debug / underlying implementation details

setEarthLocation

protected abstract void setEarthLocation()

getCommonType

public RadialDatasetSweep.Type getCommonType()

Description copied from interface: RadialDatasetSweep

If all the sweeps are the same type, return it here, else NONE

Specified by:

getCommonType in interface RadialDatasetSweep

Returns:

type of sweep, or NONE

getTimeUnits

public DateUnit getTimeUnits()

Description copied from interface: RadialDatasetSweep

Get the units of Calendar time. To get a Date, from a time value, call DateUnit.getStandardDate(double value). To get units as a String, call DateUnit.getUnitsString().

Specified by:

getTimeUnits in interface RadialDatasetSweep

Returns:

units of Calendar time

getEarthLocation

public EarthLocation getEarthLocation()

setBoundingBox

protected void setBoundingBox()

Specified by:

setBoundingBox in class TypedDatasetImpl

calcBounds

public void calcBounds()
                throws java.io.IOException

Description copied from interface: FeatureDataset

Caclulate date range and bounding box, even if the data has to be scanned. This ensures that getDateRange() and getBoundingBox() return non-null. If the collection already knows its date range and bounding box, then this has no effect.

Specified by:

calcBounds in interface FeatureDataset

Throws:

java.io.IOException - or read error.

getFeatureType

public FeatureType getFeatureType()

Description copied from interface: FeatureDataset

Contains collections of this FeatureType.

Specified by:

getFeatureType in interface FeatureDataset

Returns:

FeatureType of data

getDateRange

public DateRange getDateRange()

Description copied from interface: FeatureDataset

Date range for the entire dataset.

Specified by:

getDateRange in interface FeatureDataset

Returns:

the date range for the entire dataset, or null if unknown

getDetailInfo

public void getDetailInfo(java.util.Formatter sf)

Description copied from interface: FeatureDataset

Show debug / underlying implementation details

Specified by:

getDetailInfo in interface FeatureDataset

Parameters:

sf - append info here

getImplementationName

public java.lang.String getImplementationName()

Description copied from interface: FeatureDataset

Show who is implementing

Specified by:

getImplementationName in interface FeatureDataset

Returns:

name of implementor

close

public void close()
           throws java.io.IOException

Description copied from interface: TypedDataset

Close all resources associated with this dataset.

Specified by:

close in interface TypedDataset

Specified by:

close in interface FeatureDataset

Specified by:

close in interface FileCacheable

Overrides:

close in class TypedDatasetImpl

Throws:

java.io.IOException

sync

public boolean sync()
             throws java.io.IOException

Description copied from interface: FileCacheable

Sync() is called when the FileCacheable is found in the cache, before returning the object to the application. FileCacheable has an opportunity to freshen itself. FileCacheable mag ignore this call.

Specified by:

sync in interface FileCacheable

Returns:

true if FileCacheable was changed

Throws:

java.io.IOException - on i/o error.

setFileCache

public void setFileCache(FileCache fileCache)

Description copied from interface: FileCacheable

FileCacheable must store the FileCache and call it on close():

  public synchronized void close() throws java.io.IOException {
    if (isClosed) return;
    if (cache != null) {
      cache.release(this);
    } else {
      reallyClose();
    }
    isClosed = true;
   

Specified by:

setFileCache in interface FileCacheable

Parameters:

fileCache - must store this, use it on close as above.
