Class AcceptHeaderFactory

java.lang.Object

com.bigdata.rdf.sail.webapp.client.AcceptHeaderFactory

public class AcceptHeaderFactory
extends Object

Utility class for generating accept heades modeled on RDFFormat.getAcceptParams(Iterable, boolean, RDFFormat), but extended to handle TupleQueryResultFormat using the same base quality value.

Version:

$Id$ TODO Add a parameter for SID support or just specify as the preferredFormat when the database is using SIDs (or for any bigdata database if we support SIDs in all modes). TODO It would be nice if the formats indicated their compactness and unicode support capability. Given that other things are equal, we would prefer a format which was compact and supported unicode.

Method Detail

getAcceptParams

public static List<String> getAcceptParams(Iterable<org.openrdf.rio.RDFFormat> rdfFormats,
                           boolean requireContext,
                           org.openrdf.rio.RDFFormat preferredFormat)

Parameters:

rdfFormats -

requireContext -

preferredFormat -

Returns:

getAcceptParams

public static <T extends info.aduna.lang.FileFormat> List<String> getAcceptParams(Iterable<T> formats,
                                                                  T preferredFormat)

Return a set of accept header values annotated with quality scores.

Parameters:

formats - The set of formats which can be accepted.

preferredFormat - The preferred format (optional).

Returns:

The list of accept header values with quality scores.

getDefaultGraphAcceptHeader

public static String getDefaultGraphAcceptHeader(boolean requireContext)

Return an accept header which establishes a preference pattern for graph data. The accept header will not include any formats for which we can not discover a parser.

getDefaultSolutionsAcceptHeader

public static String getDefaultSolutionsAcceptHeader()

Return an accept header which establishes a preference pattern for solution set data. The accept header will not include any formats for which we can not discover a parser.

Note: You CAN NOT just combine the accept headers for boolean results and solution sets together because the boolean format overlaps the solution set format (they are both [application/sparql-results+xml] so putting them together blurs the quality annotations.

getDefaultBooleanAcceptHeader

public static String getDefaultBooleanAcceptHeader()

Return an accept header which establishes a preference pattern for boolean data. The accept header will not include any formats for which we can not discover a parser.
