Method Detail

isMine

public boolean isMine(FeatureType ftype,
                      NetcdfDataset ds)
               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

Specified by:

isMine in interface FeatureDatasetFactory

Parameters:

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

ds - examine this NetcdfDataset.

Returns:

true if this class knows how to create a FeatureDataset out of this NetcdfDataset.

Throws:

java.io.IOException

copy

public FeatureDatasetFactory copy()

Description copied from interface: FeatureDatasetFactory

Copy constructor. since isMine can be expensive, make copy instead of reanalyze

Specified by:

copy in interface FeatureDatasetFactory

Returns:

copy of this factory.

open

public FeatureDataset open(FeatureType ftype,
                           NetcdfDataset ncd,
                           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() return true.

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.

task - user may cancel

errlog - place errors here

Returns:

a subclass of FeatureDataset

Throws:

java.io.IOException - on error
