Method Detail

getReadParameterInfo

public Map<String,Parameter<?>> getReadParameterInfo()

Description copied from interface: CoverageSource

Describes the required (and optional) parameters that can be passed to the CoverageSource.read(CoverageReadRequest, ProgressListener) method.

Specified by:

getReadParameterInfo in interface CoverageSource

Returns:

Param a Map describing the Map for CoverageSource.read(CoverageReadRequest, ProgressListener).

getMetadata

public MetadataNode getMetadata(String metadataDomain,
                                ProgressListener listener)

Specified by:

getMetadata in interface CoverageSource

getMetadataDomains

public Set<Name> getMetadataDomains()

Specified by:

getMetadataDomains in interface CoverageSource

getOverviewsLayouts

public List<? extends RasterLayout> getOverviewsLayouts(ProgressListener listener)
                                                 throws IOException

Specified by:

getOverviewsLayouts in interface CoverageSource

Throws:

IOException

getOverviewsNumber

public int getOverviewsNumber(ProgressListener listener)
                       throws IOException

Specified by:

getOverviewsNumber in interface CoverageSource

Throws:

IOException

getName

public Name getName(ProgressListener listener)

Description copied from interface: CoverageSource

Name of the Coverage (ie data product) provided by this CoverageSource.

Specified by:

getName in interface CoverageSource

Returns:

Name of the Coverage (ie data product) provided.

ensureNotDisposed

protected void ensureNotDisposed()

getCapabilities

public EnumSet<CoverageCapabilities> getCapabilities()

Description copied from interface: CoverageSource

Set of supported CoverageCapabilities which can be used to discover capabilities of a certain CoverageSource.

You can use set membership to quickly test abilities:

 if( getCapabilities().contains( CoverageCapabilities.READ_SUBSAMPLING ) ){
     ...
 }
 

Specified by:

getCapabilities in interface CoverageSource

Returns:

a EnumSet of CoverageCapabilities which can be used to discover capabilities of this CoverageSource.

Description copied from interface: CoverageSource

Retrieves a RangeType instance which can be used to describe the codomain for the underlying coverage.

Specified by:

getRangeType in interface CoverageSource

Returns:

a RangeType instance which can be used to describe the codomain for the underlying coverage.

Throws:

IOException - in case something bad occurs

public CoordinateReferenceSystem getCoordinateReferenceSystem()

Specified by:

getCoordinateReferenceSystem in interface CoverageSource

getSpatialDomain

public CoverageSource.SpatialDomain getSpatialDomain()
                                              throws IOException

Specified by:

getInfo

public ResourceInfo getInfo(ProgressListener listener)

Description copied from interface: CoverageSource

Information describing the contents of this resource.

Please note that for FeatureContent:

• name - unique with in the context of a Service
• schema - used to identify the type of resource; usually the format or data product being represented

Specified by:

getInfo in interface CoverageSource

dispose

public void dispose()

Description copied from interface: CoverageSource

Closes this CoverageSource and releases any lock or cached information it holds.

Once a CoverageAccess has been disposed it can be seen as being in unspecified state, hence calling a method on it may have unpredictable results.

Specified by:

dispose in interface CoverageSource
