Method Details

getSourceVar

org.apache.jena.sparql.core.Var getSourceVar()

getTargetVar

org.apache.jena.sparql.core.Var getTargetVar()

getSourceVars

default Set<org.apache.jena.sparql.core.Var> getSourceVars()

Specified by:

getSourceVars in interface GeneralizedFragment2

getTargetVars

default Set<org.apache.jena.sparql.core.Var> getTargetVars()

Specified by:

getTargetVars in interface GeneralizedFragment2

getMarkedVars

default Set<org.apache.jena.sparql.core.Var> getMarkedVars()

getIntermediaryVars

default Set<org.apache.jena.sparql.core.Var> getIntermediaryVars()

reverse

default Fragment2 reverse()

isEmpty

default boolean isEmpty()

An empty relation does is equivalent to a zero-length path, i.e. it navigates from a set of resources to the same set of resources. It is expressed as an empty graph pattern (ElementGroup), and equal variables in source and target;

Returns:

getSourceConcept

default Concept getSourceConcept()

getTargetConcept

default Concept getTargetConcept()

applyNodeTransform

default Fragment2 applyNodeTransform(org.apache.jena.sparql.graph.NodeTransform nodeTransform)

Specified by:

applyNodeTransform in interface Fragment

getAsTripleOrTriplePath

default org.apache.jena.sparql.core.TriplePath getAsTripleOrTriplePath()

Upgrades triples to triple paths.

getAsTriplePath

default org.apache.jena.sparql.core.TriplePath getAsTriplePath()

If the relation is backed by a single ElementPathBlock with only a single TriplePath then return it - otherwise return null.

getAsTriple

default org.apache.jena.graph.Triple getAsTriple()
