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

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	PhysicalOpBinaryUnion	A physical operator that implements a binary union.
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	PhysicalOpNaiveNestedLoopsJoin	A physical operator that implements a local (!)
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).
