Methods

Modifier and Type	Method and Description
protected void	buildNetcdfDataset(CancelTask cancelTask) Call this to build the dataset objects in the NetcdfDataset
protected void	persistRead() read info from the persistent XML file, if it exists; overridden in AggregationExisting
void	persistWrite() Persist info (ncoords, coordValues) from joinExisting, since that can be expensive to recreate.

AggregationExisting

public AggregationExisting(NetcdfDataset ncd,
                   String dimName,
                   String recheckS)

Method Detail

buildNetcdfDataset

protected void buildNetcdfDataset(CancelTask cancelTask)
                           throws IOException

Description copied from class: Aggregation

Call this to build the dataset objects in the NetcdfDataset

Specified by:

buildNetcdfDataset in class Aggregation

Parameters:

cancelTask - maybe cancel

Throws:

IOException - on read error

rebuildDataset

protected void rebuildDataset()
                       throws IOException

Description copied from class: Aggregation

Call this when rescan has found changed datasets

Overrides:

rebuildDataset in class AggregationOuterDimension

Throws:

IOException - on read error

readTimeCoordinates

protected void readTimeCoordinates(VariableDS timeAxis,
                       CancelTask cancelTask)
                            throws IOException

Throws:

IOException

persistWrite

public void persistWrite()
                  throws IOException

Persist info (ncoords, coordValues) from joinExisting, since that can be expensive to recreate.

Overrides:

persistWrite in class Aggregation

Throws:

IOException

persistRead

protected void persistRead()

Description copied from class: Aggregation

read info from the persistent XML file, if it exists; overridden in AggregationExisting

Overrides:

persistRead in class Aggregation
