Constructor Detail

Nexrad2RadialAdapter

public Nexrad2RadialAdapter()

Nexrad2RadialAdapter

public Nexrad2RadialAdapter(NetcdfDataset ds)

Constructor.

Parameters:

ds - must be from nexrad2 IOSP

Method Detail

isMine

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

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

open

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

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

getScientificDataType

public FeatureType getScientificDataType()

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:

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.
