augmentDataset

public void augmentDataset(NetcdfDataset ds,
                  CancelTask cancelTask)

Description copied from interface: CoordSysBuilderIF

Make changes to the dataset that are needed before processing scale/offset in NetcdfDataset.

Specified by:

augmentDataset in interface CoordSysBuilderIF

Overrides:

augmentDataset in class CoordSysBuilder

Parameters:

ds - modify this dataset

cancelTask - give user a chance to bail out

findCoordinateAxes

protected void findCoordinateAxes(NetcdfDataset ds)

Description copied from class: CoordSysBuilder

Identify coordinate axes, set VarProcess.isCoordinateAxis = true. Default is to look for those referenced by _CoordinateAxes attribute. Note coordinate variables are already identified.

Overrides:

findCoordinateAxes in class CoordSysBuilder

Parameters:

ds - why

makeCoordinateTransforms

protected void makeCoordinateTransforms(NetcdfDataset ds)

Description copied from class: CoordSysBuilder

Take all previously identified Coordinate Transforms and create a CoordinateTransform object by calling CoordTransBuilder.makeCoordinateTransform().

Overrides:

makeCoordinateTransforms in class CoordSysBuilder

Parameters:

ds - why

getAxisType

protected AxisType getAxisType(NetcdfDataset ds,
                   VariableEnhanced ve)

Description copied from class: CoordSysBuilder

Identify what kind of AxisType the named variable is. Only called for variables already identified as Coordinate Axes. Default null - subclasses can override.

Overrides:

getAxisType in class CoordSysBuilder

Parameters:

ds - for this dataset

ve - a variable alreaddy identified as a Coodinate Axis

Returns:

AxisType or null if unknown.
