Method Detail

getName

Name getName(ProgressListener listener)

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

Returns:

Name of the Coverage (ie data product) provided.

Since:

2.5

getInfo

ResourceInfo getInfo(ProgressListener listener)

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

getReadParameterInfo

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

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

Returns:

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

read

CoverageResponse read(CoverageReadRequest request,
                      ProgressListener listener)
               throws IOException

Obtain a CoverageResponse from this CoverageSource given a specified DefaultCoverageRequest.

Parameters:

request - the input DefaultCoverageRequest.

Throws:

IOException

getRangeType

RangeType getRangeType(ProgressListener listener)
                throws IOException

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

Returns:

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

Throws:

IOException - in case something bad occurs

dispose

void dispose()

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.

getCapabilities

EnumSet<CoverageCapabilities> getCapabilities()

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 ) ){
     ...
 }
 

Returns:

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

getMetadata

MetadataNode getMetadata(String metadataDomain,
                         ProgressListener listener)

getMetadataDomains

Set<Name> getMetadataDomains()

getCoordinateReferenceSystem

CoordinateReferenceSystem getCoordinateReferenceSystem()

getSpatialDomain

CoverageSource.SpatialDomain getSpatialDomain()
                                       throws IOException

Throws:

IOException

getTemporalDomain

CoverageSource.TemporalDomain getTemporalDomain()
                                         throws IOException

Throws:

IOException

getVerticalDomain

CoverageSource.VerticalDomain getVerticalDomain()
                                         throws IOException
