com.hp.hpl.jena.graph.query |
Defines the graph-level Query classes, allowing multi-pattern query
over arbitrary graphs.
|
Modifier and Type | Class and Description |
---|---|
class |
ConstraintStage
A ConstraintStage implements the constraint evaluation part of a
query.
|
class |
InitialStage
The initial stage of a query, responsible for dropping the no-variables-bound seed
binding domain into the remaining stages of the query pipeline.
|
class |
PatternStage
A PatternStage is a Stage that handles some bunch of related patterns; those patterns
are encoded as Triples.
|
class |
PatternStageBase
PatternStageBase contains the features that are common to the
traditional PatternStage engine and the Faster engine.
|
Modifier and Type | Method and Description |
---|---|
Stage |
Stage.connectFrom(Stage s)
connect this stage to its supplier; return this for chaining.
|
static Stage |
Stage.initial(int count)
construct a new initial stage for the pipeline
|
Stage |
QueryHandler.patternStage(Mapping map,
ExpressionSet constraints,
Triple[] p)
produce a single Stage which will probe the underlying graph for triples
matching p and inject all the resulting bindings into the processing stream
(see Stage for details)
