Constructor Detail

CFRadialAdapter

public CFRadialAdapter()

CFRadialAdapter

public CFRadialAdapter(NetcdfDataset ds)

Constructor.

Parameters:

ds - Source NetCDF dataset

Method Detail

isMine

public java.lang.Object isMine(FeatureType wantFeatureType,
                               NetcdfDataset ncd,
                               java.util.Formatter errlog)
                        throws java.io.IOException

Description copied from interface: FeatureDatasetFactory

Determine if the factory can open this dataset as an instance of the given feature type

Parameters:

wantFeatureType - can factory open as this feature type? If null, can factory open as any feature type?

ncd - examine this NetcdfDataset.

errlog - place errors here

Returns:

"analysis object" - null if cannot open, else an Object that is passed back into FeatureDatasetFactory.open(). This allows expensive analysis results to be reused

Throws:

java.io.IOException - on read error

open

public FeatureDataset open(FeatureType ftype,
                           NetcdfDataset ncd,
                           java.lang.Object analysis,
                           CancelTask task,
                           java.util.Formatter errlog)
                    throws java.io.IOException

Description copied from interface: FeatureDatasetFactory

Open a NetcdfDataset as a FeatureDataset. Should only be called if isMine() returns non-null.

Parameters:

ftype - open as this feature type. If null, open as any feature type.

ncd - an already opened NetcdfDataset.

analysis - the object returned from isMine(). Likely given to a different instance of FeatureDatasetFactory

task - user may cancel, may be null

errlog - write error messages here, may be null

Returns:

a subclass of FeatureDataset

Throws:

java.io.IOException - on error

getScientificDataType

public FeatureType getScientificDataType()

init

public void init()

setBoundingBox

protected void setBoundingBox()

Overrides:

setBoundingBox in class AbstractRadialAdapter

setEarthLocation

protected void setEarthLocation()

Specified by:

setEarthLocation in class AbstractRadialAdapter

getCommonOrigin

public EarthLocation getCommonOrigin()

Description copied from interface: RadialDatasetSweep

If all sweeps have the same origin, return it here, else null

Returns:

common origin, or null

getRadarID

public java.lang.String getRadarID()

Returns:

radar id

getRadarName

public java.lang.String getRadarName()

Returns:

radar name

getDataFormat

public java.lang.String getDataFormat()

Returns:

data format

isVolume

public boolean isVolume()

Description copied from interface: RadialDatasetSweep

Get the basic property of Radar,

Returns:

0 if there is only one sweep

isHighResolution

public boolean isHighResolution(NetcdfDataset nds)

isStationary

public boolean isStationary()

Description copied from interface: RadialDatasetSweep

Stationary versus moving radar.

Returns:

true if this is stationary.
