com.luciad.ogc.wcs.client.TLcdGeoTIFFWCSCoverageDecoder

public final class TLcdGeoTIFFWCSCoverageDecoder
extends ALcdWCSCoverageDecoder

This is the default decoder for WCS GetCoverage responses that decodes GeoTIFF data as ALcdBasicImage. It recognizes output formats "GeoTIFF", "GTIFF", "GeoTIFFINT16", "GeoTIFFFLOAT32" (case insensitive).

Since:

2015.1

Method Details

canDecodeCoverage

public boolean canDecodeCoverage(String aOutputFormat)

Description copied from class: ALcdWCSCoverageDecoder

Checks whether this decoder can decode a GetCoverage response in the given output format. The check must be quick and may be optimistic: implementations must return true when they probably can decode a response in the given output format. When they return false, they most definitely can't decode the given output format. 'true' has the semantics of 'probably', while 'false' really means 'no'. When this method returns true, a subsequent invocation of ALcdWCSCoverageDecoder.decodeCoverage(java.lang.String, java.lang.String, java.io.InputStream, com.luciad.ogc.wcs.client.TLcdWCSGetCoverageRequest) may yet throw an IOException to indicate that this decoder couldn't decode the coverage response after all.

Specified by:

canDecodeCoverage in class ALcdWCSCoverageDecoder

Parameters:

aOutputFormat - the requested output format, never null.

Returns:

true if this decoder can probably decode a GetCoverage response in the given output format, false when it most definitely can't.

decodeCoverage

public ILcdModel decodeCoverage(String aOutputFormat,
 String aContentType,
 InputStream aContent,
 TLcdWCSGetCoverageRequest aRequest)
                         throws IOException

Description copied from class: ALcdWCSCoverageDecoder

Decodes a GetCoverage response as an ILcdModel. The model must support the imaging API, which means that it should either contain an element which is or has an ALcdImage.

An element is an ALcdImage if it is an ALcdBasicImage, ALcdMultilevelImage, ALcdImageMosaic or ALcdMultilevelImageMosaic.

An element has an ALcdImage if it is an ILcdDataObject with an ALcdImage as geometry property, as defined by a data type with a TLcdHasGeometryAnnotation in its data model.

If the model has multiple elements, only the first one will be considered. If the element is or has a ALcdMultilevelImageMosaic, only the first level will be cosid

Specified by:

decodeCoverage in class ALcdWCSCoverageDecoder

Parameters:

aOutputFormat - the requested output format, never null

aContentType - the content type (MIME type) of the GetCoverage response, possibly null

aContent - the GetCoverage response content as a stream, never null

aRequest - the request, never null

Returns:

the decoded coverage response as a model which contains an ALcdBasicImage, ALcdMultilevelImage, ALcdImageMosaic or ALcdMultilevelImageMosaic

Throws:

IOException - if this decoder couldn't decode the content
