class |
QueryIter1
This class supports a QueryIter that takes one QueryIterator as input. |
class |
QueryIter2
This class makrs a QueryIter that takes one QueryIterator as input. |
class |
QueryIter2LoopOnLeft
Binary operation done by looping on the left, and materializing the right - this is not streamed on the right See also QueryIterRepeatApply |
class |
QueryIterAssign
Extend each solution by a (var, expression) |
class |
QueryIterAssignVarValue
Extend each solution by a (var, node) When used with mustBeNewVar=false, this is a join. |
class |
QueryIterBlockTriples
|
class |
QueryIterBlockTriplesQH
An Iterator that takes a binding and executes a pattern via the Jena graph QueryHandler interface. |
class |
QueryIterCommonParent
Yield new bindings, with a fixed parent, with values from an iterator. |
class |
QueryIterConcat
A query iterator that joins two or more iterators into a single iterator. |
class |
QueryIterConvert
Iterator over another QueryIterator, applying a converter function to each object that is returned by .next() |
class |
QueryIterDefaulting
An iterator that returns at least one element from another iterator or a default value (once) if the wrapped iterator returns nothing. |

class |
QueryIterJoin
Join by materializing the RHS - this is not streamed |
class |
QueryIterJoinBase
Join or LeftJoin by calculating both sides, then doing the join It usually better to use substitute algorithm (not this QueryIterator in other words) as that is effectively indexing from one side into the other. |
