Classes in se.liu.ida.hefquin.engine.queryplan.executable.impl.ops that implement UnaryExecutableOp

Modifier and Type	Class	Description
class	BaseForExecOpIndexNestedLoopsJoinWithRequestOps<QueryType extends Query,MemberType extends FederationMember>	Abstract base class to implement index nested loops joins by using request operators.
class	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.
class	BaseForExecOpIndexNestedLoopsJoinWithSolMapsRequests<QueryType extends Query,MemberType extends FederationMember,ReqType extends DataRetrievalRequest>
class	BaseForExecOpParallelBindJoin<QueryType extends Query,MemberType extends FederationMember,ReqType extends DataRetrievalRequest,RespType extends DataRetrievalResponse<?>>	A generic implementation of a batch-based bind-join algorithm that issues the bind-join requests without blocking, handling the processing of their responses in parallel (in the threads that the federation access manager uses to perform the requests).
class	BaseForExecOpParallelBindJoinSPARQL	A base class for all variations of our parallelized, batch-based bind-join algorithm that use some form of SPARQL requests.
class	BaseForExecOpSequentialBindJoin<QueryType extends Query,MemberType extends FederationMember>	A generic implementation of batch-based bind-join algorithm that performs the bind-join requests sequentially, one after another, for which it uses executable request operators.
class	BaseForExecOpSequentialBindJoinSPARQL	A base class for all variations of our sequential, batch-based bind-join algorithm that use some form of SPARQL requests.
class	BaseForUnaryExecOpWithCollectedInput	Base class for all implementations of UnaryExecutableOp that work more effectively if at least a minimum number of input solution mappings are available to process.
class	ExecOpBind	To be used for BIND clauses.
class	ExecOpDuplicateRemoval	To be used for DISTINCT clauses.
class	ExecOpFilter
class	ExecOpGlobalToLocal
class	ExecOpIndexNestedLoopsJoinSPARQL
class	ExecOpIndexNestedLoopsJoinTPF	May be used for brTPF servers as well (in fact, BRTPFServer is a specialization of TPFServer).
class	ExecOpLocalToGlobal
class	ExecOpLookupJoinViaWrapperWithoutParamVars
class	ExecOpLookupJoinViaWrapperWithParamVars
class	ExecOpParallelBindJoinSPARQLwithFILTER	Implementation of the parallel, batch-based bind-join algorithm that uses a FILTERs to capture the potential join partners that are sent to the federation member.
class	ExecOpParallelBindJoinSPARQLwithUNION	Implementation of the parallel, batch-based bind-join algorithm that uses UNION clauses with FILTERs inside.
class	ExecOpParallelBindJoinSPARQLwithVALUES	Implementation of the parallel, batch-based bind-join algorithm that uses a VALUES clause to capture the potential join partners that are sent to the federation member.
class	ExecOpParallelMultiwayLeftJoin	TODO: Provide a description of the algorithm implemented by this class.
class	ExecOpSequentialBindJoinBRTPF	Implementation of the sequential, batch-based bind-join algorithm for cases in which the federation member accessed by the algorithm supports the brTPF interface.

class	ExecOpSequentialBindJoinSPARQLwithVALUESorFILTER	Implementation of the sequential, batch-based bind-join algorithm that starts by using a VALUES clause exactly as done by ExecOpSequentialBindJoinSPARQLwithVALUES.
class	ExecOpSequentialBindJoinSPARQLwithVarRenaming	Implementation of the sequential, batch-based bind-join algorithm that uses UNION clauses with variable renaming (as proposed in the FedX paper by Schwarte et al. 2011, where it is called "bound join").
class	ExecOpUnfold	To be used for UNFOLD clauses.
class	UnaryExecutableOpBase	Top-level base class for all implementations of UnaryExecutableOp.
class	UnaryExecutableOpBaseWithoutBlocking	Base class for all implementations of UnaryExecutableOp that do not need to process the input solution mappings in batches (the filter operator is a typical example).
