Classes
BaseSparqlView
Abstract Base class for SPARQL Views which are Graphs which are generated from SPARQL Queries and get automatically updated when the Store they are attached to changes.
BindingGroup
Represents an Group of Bindings which is used when executing Queries with GROUP BY clauses.
ExplainQueryProcessor
A Query Processor which evaluates queries while printing explanations to any/all of Debug, Trace, Console Standard Output and Console Standard Error.
FederatedSparqlQueryClient
A class for connecting to multiple remote SPARQL endpoints and federating queries over them with the results merged locally.
FederatedSparqlRemoteEndpoint
A Class for connecting to multiple remote SPARQL Endpoints and federating queries over them with the data merging done locally.
FullTextHelper
Helper Class containing constants and static functions for use with Full Text Search.
GenericQueryProcessor
A SPARQL Query Processor where the query is processed by passing it to the Query() method of an IQueryable
LeviathanLeftJoinBinder
Special Temporary Results Binder used during LeftJoin's.
LeviathanQueryOptions
A class encapsulating run-time options that can be configured for a Leviathan
LeviathanQueryProcessor

NativeSparqlView
Represents a SPARQL View over an arbitrary native Triple Store.
NumericTypesHelper
Class containing helper functions related to SPARQL numeric types.
QueryProcessorBase
Provides a default implementation of the methods that allow a query processor to run asynchronously with a results callback.
RdfQueryException
Class for representing errors that occur while querying RDF.
RdfQueryTimeoutException

RdfReasoningException
Class for representing Exceptions occurring in RDF reasoners.
RemoteQueryProcessor
A SPARQL Query Processor where the query is processed by passing it to a remote SPARQL endpoint.
ResultsHandlerExtensions
Extension methods for ISparql
SimpleQueryProcessor

SparqlEvaluationContext
Stores information about the Evaluation of a Query during it's evaluation.
SparqlNodeComparer
Comparer class for implementing the SPARQL semantics for the relational operators.
SparqlOrderingComparer
Comparer class for use in SPARQL ORDER BY - implements the Semantics broadly similar to the relational operator but instead of erroring using Node/Lexical ordering where an error would occur it makes an appropriate decision.
SparqlParameterizedString
A SPARQL Parameterized String is a String that can contain parameters in the same fashion as a SQL command string.
SparqlQuery
Represents a SPARQL Query.
SparqlQueryClient
A class for connecting to a remote SPARQL endpoint and making queries against it using the System.Net.Http library.
SparqlRemoteEndpoint
A Class for connecting to a remote SPARQL Endpoint and executing Queries against it.
SparqlResult
Class for representing a Row of a Sparql Result Set.
SparqlResultBinder
Helper Class used in the execution of Sparql Queries.
SparqlResultFactory
SparqlResultSet
Class for representing Sparql Result Sets.
SparqlSpecsHelper
Class containing Helper information and methods pertaining to the Sparql Query Language for RDF.
SparqlVariable
Class of Sparql Variables.
SparqlView
Represents a SPARQL View over an in-memory store.
