Method Detail

isMine

public Object isMine(FeatureType wantFeatureType,
                     NetcdfDataset ncd,
                     Formatter errlog)

Description copied from interface: FeatureDatasetFactory

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

Specified by:

isMine in interface FeatureDatasetFactory

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,
                           Object analysis,
                           CancelTask task,
                           Formatter errlog)
                    throws IOException

Description copied from interface: FeatureDatasetFactory

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

Specified by:

open in interface FeatureDatasetFactory

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:

IOException - on error

getFeatureTypes

public FeatureType[] getFeatureTypes()

Description copied from interface: FeatureDatasetFactory

This Factory can open these types of Feature datasets.

Specified by:

getFeatureTypes in interface FeatureDatasetFactory

Returns:

array of FeatureType
