createViewable

public Viewable createViewable(int which)
                                          throws java.lang.InstantiationException,
                                                 java.lang.ArrayIndexOutOfBoundsException,
                                                 DataAccessException

return a Viewable object appropriate for this file format, or null if a file is not attached to this format or the format is not supported by a Viewable class. The default implementation returns a ReaderEnabledViewable using the result of createReaderND(); however, some implementations may override this to return a format-specific Viewable.

Parameters:

which - an index to the desired array where 0 is the first array.

Throws:

java.lang.ArrayIndexOutOfBoundsException - if which < 0 or > the number of arrays in the file.

DataAccessException - if an IO error occurs or the data is otherwise inaccessible at the moment.

java.lang.InstantiationException - if the instantiation of the Viewable fails
