Method Detail

isAvailable

public boolean isAvailable()

Description copied from interface: WFSResponseFactory

Indicates whether the factory instance is able to create parser instances.

Returns:

true if there's nothing preventing the creation of the parsers this factory should produce

See Also:

WFSResponseFactory.isAvailable()

canProcess

public boolean canProcess(WFSRequest request,
                          String contentType)

Checks if this factory can create a parser for the potential responses of the given WFS request.

For instance, this factory can create a parser as long as the request is a GetFeature request and the request output format matches "text/xml; subtype=gml/3.1.1".

Returns:

true if this factory can create a parser for the responses of the given request

WFSResponseFactory#canProcess(WFSOperationType, String)

createResponseImpl

protected WFSResponse createResponseImpl(WFSRequest request,
                                         HTTPResponse response,
                                         InputStream in)
                                  throws IOException

Description copied from class: AbstractWFSResponseFactory

Has to be implemented to turn the request and response into a proper WFSResponse.

Specified by:

createResponseImpl in class AbstractWFSResponseFactory

in - The stream to read the response from. It is safe not to close this stream explicitly but to dispose the response instead.

Returns:

The actual response

Throws:

IOException

isValidResponseHead

protected boolean isValidResponseHead(String head)

Specified by:

isValidResponseHead in class AbstractWFSResponseFactory

Parameters:

head - The first couple of characters from the response, typically the first 512

Returns:

canProcess

public boolean canProcess(WFSOperationType operation)

parser

protected abstract GetFeatureParser parser(GetFeatureRequest request,
                                           InputStream in)
                                    throws IOException

Throws:

IOException

getSupportedVersions

protected abstract List<String> getSupportedVersions()
