Method Detail

instance

public static Strategy instance(Strategy[] strategies)

strategies - The import strategies to use.

Returns:

An import strategy.

Throws:

java.lang.NullPointerException - if the argument is null.

java.lang.IllegalArgumentException - if the number of strategies is 0.

getData

public DataImpl getData(NetcdfAdapter adapter)
                 throws java.io.IOException,
                        VisADException,
                        java.rmi.RemoteException,
                        BadFormException,
                        java.lang.OutOfMemoryError

Returns a VisAD data object corresponding to the netCDF dataset.

Specified by:

getData in class Strategy

Parameters:

adapter - The netCDF-to-VisAD adapter.

Returns:

The top-level, VisAD data object of the netCDF dataset.

Throws:

VisADException - if a problem occurs in core VisAD -- probably because a VisAD object couldn't be created.

java.io.IOException - if a data access I/O failure occurs.

BadFormException - if the netCDF dataset doesn't conform to conventions implicit in constructing View.

java.lang.OutOfMemoryError - if the netCDF dataset couldn't be imported due to insufficient memory.

java.rmi.RemoteException - if a Java RMI failure occurs.
