Method Details

evaluatePatternOverRDFView

List<SolutionMapping> evaluatePatternOverRDFView(SPARQLGraphPattern pattern,
 String data)
                                          throws WrappedRESTEndpoint.DataConversionException

Assuming the given string is the content of a response retrieved when issuing a request to this REST endpoint, this method returns the result of evaluating the given graph pattern over an RDF view of this content.

Parameters:

pattern - - the graph pattern to be evaluated over the RDF view of the given data

data - - the content of a response retrieved via a successful request to this REST endpoint

Returns:

the result of evaluating the pattern over the RDF view, in the form of a sequence of solution mappings

Throws:

WrappedRESTEndpoint.DataConversionException - if the conversion into RDF fails
