                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

Specified by:

rebuildDataset in class Aggregation

Throws:

IOException - on read error

reallyRead

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

Description copied from interface: ProxyReader

Read all the data for a Variable.

Specified by:

reallyRead in interface ProxyReader

Parameters:

mainv - the client Variable

cancelTask - user may cancel

Returns:

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

Throws:

IOException - on error

reallyRead

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

Description copied from interface: ProxyReader

Read a section of the data for a Variable.

Specified by:

reallyRead in interface ProxyReader

Parameters:

mainv - the client Variable

wantSection - the section of data to read.

cancelTask - user may cancel

Returns:

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

Throws:

IOException - on error

makeDataset

protected Aggregation.Dataset makeDataset(String cacheName,
                              String location,
                              String id,
                              String ncoordS,

                              EnumSet<NetcdfDataset.Enhance> enhance,
                              FileFactory reader)

Description copied from class: Aggregation

Dataset factory, so subclasses can override

Overrides:

makeDataset in class Aggregation

Parameters:

cacheName - a unique name to use for caching

location - attribute "location" on the netcdf element

id - attribute "id" on the netcdf element

ncoordS - attribute "ncoords" on the netcdf element

coordValueS - attribute "coordValue" on the netcdf element

sectionSpec - attribute "sectionSpec" on the netcdf element

enhance - open dataset in enhance mode NOT USED

reader - factory for reading this netcdf dataset

Returns:

a Aggregation.Dataset
