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)
                        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
