Constructor Detail

ArcSDEGridCoverage2DReaderJAI

public ArcSDEGridCoverage2DReaderJAI(ArcSDERasterFormat parent,
                                     RasterReaderFactory rasterReaderFactory,
                                     RasterDatasetInfo rasterInfo,
                                     Hints hints)
                              throws java.io.IOException
Throws:
java.io.IOException
Method Detail

getFormat

public org.opengis.coverage.grid.Format getFormat()
See Also:
GridCoverageReader.getFormat()

getInfo

public ServiceInfo getInfo()
Description copied from class: AbstractGridCoverage2DReader
Information about this source.

Subclasses should provide additional format specific information.

Overrides:
getInfo in class AbstractGridCoverage2DReader
Returns:
ServiceInfo describing getSource().

read

public GridCoverage2D read(org.opengis.parameter.GeneralParameterValue[] params)
                    throws java.io.IOException
Description copied from class: AbstractGridCoverage2DReader
Read the current grid coverage from the stream.

Example:


 
The method AbstractGridCoverage2DReader.hasMoreGridCoverages() should be invoked first in order to verify that a coverage is available.

Specified by:
read in interface org.opengis.coverage.grid.GridCoverageReader
Specified by:
read in class AbstractGridCoverage2DReader
Parameters:
params - Optional parameters matching Format.getReadParameters().
Returns:
A new grid coverage from the input source, or null if the requested envelope is outside the data bounds
Throws:
java.io.IOException - if a read operation failed for some other input/output reason, including FileNotFoundException if no file with the given name can be found, or IIOException if an error was thrown by the underlying image library.
