catalog

protected GranuleCatalog catalog

Constructor Detail

ImageMosaicConfigHandler

public ImageMosaicConfigHandler(CatalogBuilderConfiguration configuration,
                                ImageMosaicEventHandlers eventHandler)

Default constructor

Method Detail

reset

public void reset()

Perform proper clean up.

Make sure to call this method when you are not running the ImageMosaicConfigHandler or bad things can happen. If it is running, please stop it first.

getStop

public boolean getStop()

stop

public void stop()

buildCatalog

protected GranuleCatalog buildCatalog()
                               throws IOException

Throws:

IOException

coverageExists

protected boolean coverageExists(String coverageName)
                          throws IOException

Check whether the specified coverage already exist in the reader. This allows to get the rasterManager associated with that coverage instead of creating a new one.

Parameters:

coverageName - the name of the coverage to be searched

Returns:

true in case that coverage already exists

Throws:

IOException

updateConfiguration

public void updateConfiguration(GridCoverage2DReader coverageReader,
                                String inputCoverageName,
                                File fileBeingProcessed,
                                int fileIndex,
                                double numFiles,

                         throws IOException,
                                GranuleHandlingException,

                                TransformException

Use the passed coverageReader to create or update the all the needed configurations
It not responsible of the passed coverageReader which should be disposed outside (in the caller).

Throws:

IOException

GranuleHandlingException

NoSuchAuthorityCodeException

FactoryException

TransformException

getTargetCoverageName

public String getTargetCoverageName(GridCoverage2DReader inputCoverageReader,
                                    String inputCoverageName)

Get the name of the target coverage for a given reader. For most input coverages, the target coverage is simply the default coverage. For structured coverages the target coverage has the same name as the input coverage.

Parameters:

inputCoverageReader - the coverage being added to the index

inputCoverageName - the name of the input coverage

Returns:

the target coverage name for the input coverage
