Class GridCoverageReaderProgressAdapter

Object

BaseGridCoverageProgressAdapter

GridCoverageReaderProgressAdapter

All Implemented Interfaces:

EventListener, IIOReadProgressListener, IIOReadUpdateListener, IIOReadWarningListener

public class GridCoverageReaderProgressAdapter
extends BaseGridCoverageProgressAdapter
implements IIOReadProgressListener, IIOReadUpdateListener, IIOReadWarningListener

This class provide a means to wrap a GeoTools ProgressListener and have it control an ImageReader while it is actually doing a ImageReader.read(int) operation.

We also give user the ability to cancel the reading process
