Method Detail

buildNetcdfDataset

protected void buildNetcdfDataset(CancelTask cancelTask)
                           throws java.io.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:

java.io.IOException - on read error

rebuildDataset

protected void rebuildDataset()
                       throws java.io.IOException

Description copied from class: Aggregation

Call this when rescan has found changed datasets

Overrides:

rebuildDataset in class AggregationOuterDimension

Throws:

java.io.IOException - on read error

readTimeCoordinates

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

Throws:

java.io.IOException

persistWrite

public void persistWrite()
                  throws java.io.IOException

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

Overrides:

persistWrite in class Aggregation

Throws:

java.io.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
