Constructor Detail

WCSConnector

public WCSConnector(URL url)
             throws ConnectException,
                    IOException

Throws:

ConnectException

IOException

Method Detail

getName

public String getName()

Returns the string "WCSDriver", which is the driver's name.

Returns:

String

setHost

public void setHost(String host)
             throws IOException

Sets the server that we want to connect to.

Parameters:

host -

Throws:

IOException

getLabel

public String getLabel()

Returns a human-readable string containing the server's name.

Returns:

String

getVersion

public String getVersion()

Returns a string containing the server's WCS version number.

Returns:

String

getDescription

public String getDescription()

Returns name and description of the server. It is supposed to be used as the source of the abstract field in your application's interface.

Devuelve nombre y descripción (abstract) del servidor.

Returns:

String

getLayer

public WCSLayerNode getLayer(String layerName)

Returns the layer descriptor for a given coverage name.

Parameters:

layerName -

Returns:

WCSLayer

getLayerList

public WCSLayerNode[] getLayerList()

Returns an array of WCSLayer's with the descriptors of all coverages

Returns:

WCSLayer[]

connect

public boolean connect(boolean override,
              ICancellable cancel)
                throws IOException

Establishes the connection to the WCS server. Connecting to a WCS is an abstraction.

Actually, it sends a GetCapabilities and a general DescribeCoverage request (not a coverage-specific DescribeCoverage request) to read the necessary data for building further GetCoverage requests.

Parameters:

override -

Throws:

IOException.

IOException

close

No close operation is needed since WCS service it is a non-session based protocol. So, this does nothing and you can omit it.

getLabel

public String getLabel(String coverageName)

Returns the label of an specific coverage given by the coverage name

Parameters:

coverage - name (string)

Returns:

string

getFullExtent

public Rectangle2D getFullExtent(String coverageName,
                        String srs)
                          throws IOException

Returns the coverage's MAX extent from the server.

Returns:

Rectangle2D

Throws:

IOException

getMaxResolution

public Point2D getMaxResolution(String coverageName)

Returns the max resolution of a specific coverage given by the coverage's name.

Parameters:

coverage - name (string)

Returns:

double
