Method Detail

buildDataset

protected void buildDataset(boolean isNew,
                            CancelTask cancelTask)
                     throws java.io.IOException

Specified by:

buildDataset in class Aggregation

Throws:

java.io.IOException

addUnionDataset

public void addUnionDataset(NetcdfDataset ds)

Add a nested union dataset, which has been opened externally

Parameters:

ds - add this dataset

getUnionDatasets

public java.util.List<NetcdfDataset> getUnionDatasets()

Get the list of NetcdfDataset that are part of this union

Returns:

List in the union

close

public void close()
           throws java.io.IOException

Release all resources associated with the aggregation

Overrides:

close in class Aggregation

Throws:
