All Superinterfaces:

AutoCloseable, DataSource

public interface GridDataSource
extends DataSource

Low-level interface to multidimensional grids, used by DataReadingStrategy. TODO axis order issues: should we define that the returned Array must have the x axis varying fastest, irrespective of the ordering of the underlying data grid? GG: Yes, probably...

Read an Array4D of data from the underlying data source

Parameters:

variableId - The variable ID to read

tmin - The minimum time index in the underlying data

tmax - The maximum time index in the underlying data

zmin - The minimum z index in the underlying data

zmax - The maximum z index in the underlying data

ymin - The minimum y index in the underlying data

ymax - The maximum y index in the underlying data

xmin - The minimum x index in the underlying data

xmax - The maximum x index in the underlying data

Returns:

An Array4D containing the data which was read

Throws:

IOException - If there is an IO problem accessing the data

DataReadingException - If there is another issue reading the data
