Constructor Details

RasterManager

public RasterManager(ImageMosaicReader parentReader,
 MosaicConfigurationBean configuration)
              throws IOException

Throws:

IOException

Method Details

read

public Collection<GridCoverage2D> read(GeneralParameterValue[] params)
                                throws IOException

Throws:

IOException

getPathType

public PathType getPathType()

getCoverageIdentifier

public String getCoverageIdentifier()

getHints

public Hints getHints()

getCoverageFactory

public GridCoverageFactory getCoverageFactory()

getTypeName

public String getTypeName()

hasAlternativeCRS

public boolean hasAlternativeCRS(Integer epsgCode)
                          throws IOException

Checks if this EPSG code matches at least one feature. Since this method may perform a database query to find out, it's important to call it last while performing conditionals, leaving cheaper tests first.

Throws:

IOException

getGranuleCatalog

public GranuleCatalog getGranuleCatalog()

createStore

public void createStore(SimpleFeatureType indexSchema)
                 throws IOException

Create a store for the coverage related to this RasterManager using the provided schema

Throws:

IOException

removeStore

public void removeStore(String typeName,
 boolean forceDelete,
 boolean checkForReferences)
                 throws IOException

Remove a store for the coverage related to this RasterManager

Throws:

IOException
