Classes in se.liu.ida.hefquin.engine.queryplan.physical.impl that implement UnaryPhysicalOp

Modifier and Type	Class	Description
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	PhysicalOpBind
class	PhysicalOpBindJoinBRTPF	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	PhysicalOpBindJoinSPARQL	A physical operator that implements a batch-based bind-join algorithm for SPARQL endpoints that can be used in different variations.
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	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	PhysicalOpLookupJoinViaWrapper	A physical operator that ..
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	PhysicalOpUnfold
