Reading is a two steps process: The input file must be set first, then the actual reading is performed with the <A HREF="../../../../org/geotools/coverage/io/AbstractGridCoverageReader.html#getGridCoverage(int)"><CODE>getGridCoverage(int)</CODE></A>. Example: <blockquote><pre> AbstractGridCoverageReader reader = ... reader.<A HREF="../../../../org/geotools/coverage/io/AbstractGridCoverageReader.html#setInput(java.lang.Object, boolean)"><CODE>setInput</CODE></A>(new File("MyCoverage.dat"), true); GridCoverage coverage = reader.<A HREF="../../../../org/geotools/coverage/io/AbstractGridCoverageReader.html#getGridCoverage(int)"><CODE>getGridCoverage</CODE></A>(0); </pre></blockquote> Subclasses needs to implements at least the following methods: <ul> <li><A HREF="../../../../org/geotools/coverage/io/AbstractGridCoverageReader.html#getCoordinateReferenceSystem(int)"><CODE>getCoordinateReferenceSystem(int)</CODE></A></li> <li><A HREF="../../../../org/geotools/coverage/io/AbstractGridCoverageReader.html#getEnvelope(int)"><CODE>getEnvelope(int)</CODE></A></li> </ul> The default implementation should be able to create acceptable grid coverage using informations provided by the two above-mentioned methods.
