Subclasses of BaseForPhysicalOps in se.liu.ida.hefquin.engine.queryplan.physical.impl

Modifier and Type	Class	Description
class	BaseForPhysicalOpBinaryJoin	Base class for physical operators that implement some form of a binary join algorithm; i.e., these algorithms consume two sequences of input solution mappings (produced by the two sub-plans under this operator) and join these the solution mappings from these two sequences locally (i.e., within in the engine rather than by interacting with any federation member).
class	BaseForPhysicalOpMultiwayJoin	Base class for physical operators that implement some form of a multi-way join algorithm.
class	BaseForPhysicalOpMultiwayLeftJoin	Base class for physical operators that implement some form of a multi-way left join algorithm.
class	BaseForPhysicalOpSingleInputJoin	Base class for physical operators that implement some form of a join algorithm that consumes only one input and produces the other input as part of the algorithm itself.
class	PhysicalOpBinaryUnion	A physical operator that implements a binary union.
class	PhysicalOpBindJoin	A physical operator that implements (a batching version of) the bind join algorithm for cases in which the federation member accessed by the algorithm supports the brTPF interface.
class	PhysicalOpBindJoinWithFILTER	A physical operator that implements (a batching version of) the bind join algorithm using FILTERs to capture the potential join partners that are sent to the federation member.
class	PhysicalOpBindJoinWithUNION	A physical operator that implements (a batching version of) the bind join algorithm using UNION.
class	PhysicalOpBindJoinWithVALUES	A physical operator that implements (a batching version of) the bind join algorithm using a VALUES clause to capture the potential join partners that are sent to the federation member.
class	PhysicalOpFilter	A physical operator that filters the input solution mappings.
class	PhysicalOpGlobalToLocal	A physical operator that applies a given vocabulary mapping to all input solution mappings, converting them from using global vocabulary terms to using local vocabulary terms.
class	PhysicalOpHashJoin	A physical operator that implements the hash join algorithm to perform an inner join of two sequences of input solution mappings (produced by the two sub-plans under this operator).
class	PhysicalOpHashRJoin	A physical operator that implements the hash join algorithm to perform a right outer join of two sequences of input solution mappings (produced by the two sub-plans under this operator).
class	PhysicalOpIndexNestedLoopsJoin	A physical operator that implements a version of the index nested loops join algorithm where the federation member is used as an index to request join partners for the input solution mappings.
class	PhysicalOpLocalToGlobal	A physical operator that applies a given vocabulary mapping to all input solution mappings, converting them from using local vocabulary terms to using global vocabulary terms.
class	PhysicalOpMultiwayUnion	A physical operator that implements a multi-way union.
class	PhysicalOpNaiveNestedLoopsJoin	A physical operator that implements a local (!)
class	PhysicalOpParallelMultiLeftJoin	A physical operator that implements a left-outer join for multiple optional parts; as a unary operator, the operator has a single input, which provides the solutions of the non-optional part.
class	PhysicalOpRequest<ReqType extends DataRetrievalRequest,MemberType extends FederationMember>	A physical operator that performs a request at a federation member and, then, outputs the solution mappings obtained via this request.
class	PhysicalOpSymmetricHashJoin	A physical operator that implements the symmetric hash join algorithm to perform an inner join of two sequences of input solution mappings (produced by the two sub-plans under this operator).
