Constructor Detail

AbstractWFSRequest

protected AbstractWFSRequest(String version,
                             String id,
                             String handle,
                             Map<String,String> vendorSpecificParameter)

Creates a new AbstractWFSRequest instance.

Parameters:

version -

id -

handle -

vendorSpecificParameter -

Method Detail

getServiceName

public String getServiceName()

Returns the value of the service attribute (WFS).

Returns:

the value of the service attribute (WFS)

getHandle

public String getHandle()

Returns the value of the handle attribute.

The purpose of the handle attribute is to allow a client application to associate a mnemonic name with a request for error handling purposes. If a handle is specified, and an exception is encountered, a Web Feature Service may use the handle to identify the offending element.

Returns:

the value of the handle attribute

checkVersionParameter

protected static String checkVersionParameter(Map<String,String> model)
                                       throws InvalidParameterValueException,
                                              MissingParameterValueException

Checks that the "VERSION" parameter value equals a supported version.

Parameters:

model - contains the parameters of the request

Returns:

value for "VERSION" parameter, never null

Throws:

InvalidParameterValueException

MissingParameterValueException

checkServiceParameter

protected static void checkServiceParameter(Map<String,String> model)
                                     throws InconsistentRequestException,
                                            MissingParameterValueException

Checks that the "SERVICE" parameter value equals the name of the service. TODO move this to AbstractOGCWebServiceRequest

Parameters:

model - contains the parameters of the request

Throws:

InconsistentRequestException - if parameter is not present or does not the service name

MissingParameterValueException

extractTypeNames

protected static QualifiedName[] extractTypeNames(Map<String,String> kvp)
                                           throws InvalidParameterValueException

Extracts the qualified type names from the TYPENAME parameter.

Parameters:

kvp -

Returns:

qualified type names (empty array if TYPENAME parameter is not present)

Throws:

InvalidParameterValueException

extractNamespaceParameter

protected static NamespaceContext extractNamespaceParameter(Map<String,String> model)
                                                     throws InvalidParameterValueException

Extracts the namespace bindings from the NAMESPACE parameter.

Example:

• NAMESPACE=xmlns(myns=http://www.someserver.com),xmlns(yourns=http://www.someotherserver.com)

The default namespace may also be bound (two variants are supported):

• NAMESPACE=xmlns(=http://www.someserver.com)
• NAMESPACE=xmlns(http://www.someserver.com)

Parameters:

model - the parameters of the request

Returns:

namespace context

Throws:

InvalidParameterValueException

extractBBOXFilter

protected static Filter extractBBOXFilter(Map<String,String> model)
                                   throws InvalidParameterValueException

Extracts a Filter from the BBOX parameter. TODO handle other dimension count and crs

Parameters:

model -

Returns:

filter representing the BBOX parameter (null, if no BBOX parameter specified)

Throws:

InvalidParameterValueException

extractFilters

protected static Map<QualifiedName,Filter> extractFilters(Map<String,String> kvp,
                                                          QualifiedName[] typeNames)
                                                   throws InvalidParameterValueException

Extracts the FILTER parameter and assigns them to the requested type names.

This is necessary, because it is allowed to specify a filter for each requested feature type.

Parameters:

kvp -

typeNames -

Returns:

map with the assignments of type names to filters

Throws:

InvalidParameterValueException
