Classes in se.liu.ida.hefquin.engine.queryplan.physical.impl used by se.liu.ida.hefquin.engine.queryplan.physical.implClassDescriptionBase 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).Top-level base class for all implementations of
PhysicalOperator.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. -
