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

addVariable

public void addVariable(String varName)

Add a name for a variableAgg element

Parameters:

varName - name of agg variable

buildCoords

protected void buildCoords(CancelTask cancelTask)
                    throws IOException

Throws:

IOException

readTimeCoordinates

protected void readTimeCoordinates(Variable.Builder timeAxis,
                                   CancelTask cancelTask)
                            throws IOException

Throws:

IOException

getTotalCoords

protected int getTotalCoords()

promoteGlobalAttributes

protected void promoteGlobalAttributes(ucar.nc2.internal.ncml.AggDatasetOuter typicalDataset)
                                throws IOException

Throws:

IOException

reallyRead

public Array reallyRead(Variable mainv,
                        Section section,
                        CancelTask cancelTask)
                 throws IOException,
                        InvalidRangeException

Read a section of an aggregation variable.

Specified by:

reallyRead in interface ProxyReader

Parameters:

section - read just this section of the data, array of Range

mainv - the client Variable

cancelTask - user may cancel

Returns:

the data array section

Throws:

IOException - on error

InvalidRangeException - if section has incorrect rank or illegal shape.

reallyRead

public Array reallyRead(Variable mainv,
                        CancelTask cancelTask)
                 throws IOException

Read an aggregation variable: A variable whose data spans multiple files. This is an implementation of ProxyReader, so must fulfill that contract.

Specified by:

reallyRead in interface ProxyReader

Parameters:

mainv - the aggregation variable

cancelTask - user may cancel

Returns:

memory resident Array containing the data. Will have same shape as the Variable.

Throws:

IOException - on error
