ClassesClassDescriptionAn abstract base class for the different variants to implement the bind join algorithm.A base class for all variations of the bind join algorithm that use some form of SPARQL requests.A generic implementation of the bind join algorithm that uses executable request operators for performing the requests to the federation member.An abstract base class for implementations of the (external) index nested loops join algorithm.BaseForExecOpIndexNestedLoopsJoinWithRequestOps<QueryType extends Query,
MemberType extends FederationMember> Abstract base class to implement index nested loops joins by using request operators.BaseForExecOpIndexNestedLoopsJoinWithRequests<QueryType extends Query,MemberType extends FederationMember, ReqType extends DataRetrievalRequest, RespType extends DataRetrievalResponse> Abstract base class to implement index nested loops joins by issuing requests directly and, then, using response processors.BaseForExecOpIndexNestedLoopsJoinWithSolMapsRequests<QueryType extends Query,MemberType extends FederationMember, ReqType extends DataRetrievalRequest> BaseForExecOpIndexNestedLoopsJoinWithTPFRequests<MemberType extends FederationMember>Base class for implementations of request operators.BaseForExecOpRequestWithPaging<ReqType extends DataRetrievalRequest,MemberType extends FederationMember, PageReqType extends DataRetrievalRequest, PageRespType extends DataRetrievalResponse> Base class for implementations of request operators with requests that have to be broken into multiple requests to handle paging.BaseForExecOpRequestWithTPFPaging<ReqType extends DataRetrievalRequest,MemberType extends FederationMember, PageReqType extends DataRetrievalRequest> Base class for implementations of paging-based request operators where pages areTPFResponseobjects.Top-level base class for all implementations ofExecutableOperator.BaseForExecOpSolMapsRequest<ReqType extends DataRetrievalRequest,MemberType extends FederationMember> BaseForExecOpTriplePatternRequestWithTPF<MemberType extends FederationMember>Base class for implementations of request operators with triple pattern requests that are broken into TPF requests to handle paging.BaseForExecOpTriplesRequest<ReqType extends DataRetrievalRequest,MemberType extends FederationMember> Base class for implementations of request operators with requests that return triples and that can be performed as is.Top-level base class for all implementations ofBinaryExecutableOp.Implementation of (a batching version of) the bind join algorithm for cases in which the federation member accessed by the algorithm supports the brTPF interface.Implementation of (a batching version of) the bind join algorithm that uses FILTERs to capture the potential join partners that are sent to the federation member.Implementation of (a batching version of) the bind join algorithm that uses UNION.Implementation of (a batching version of) the bind join algorithm that uses a VALUES clause to capture the potential join partners that are sent to the federation member.A right outer join version of the hash join algorithm implemented inExecOpHashJoin.Attention, this is a purely local implementation of the nested loops join algorithm---nothing fancy, no requests to federation members or anything.TODO: Provide a description of the algorithm implemented by this class.Implementation of an operator to request a (complete) TPF from a brTPF server.Implementation of an operator to request a (complete) TPF from a TPF server.Implementation of the symmetric hash join algorithm.Top-level base class for all implementations ofNaryExecutableOp.Top-level base class for all implementations ofNullaryExecutableOp.Top-level base class for all implementations ofUnaryExecutableOp.
