class
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
Base class for physical operators that implement
some form of a multi-way join algorithm.
class
Base class for physical operators that implement
some form of a multi-way left join algorithm.
class
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
A physical operator that implements a binary union.
class
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
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
A physical operator that implements (a batching version of) the bind
join algorithm using UNION.
class
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
A physical operator that filters the input solution mappings.
class
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
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
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
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
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
A physical operator that implements a multi-way union.
class
A physical operator that implements a local (!)
class
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
A physical operator that performs a request at a federation member
and, then, outputs the solution mappings obtained via this request.
class
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).
