All Known Implementing Classes:

BlazeEdge, BlazeVertex, BlazeVertexProperty, EmptyBlazeVertexProperty

public interface BlazeElement
extends org.apache.tinkerpop.gremlin.structure.Element

Method Detail

graph

BlazeGraph graph()

Strengthen return type to BlazeGraph.

Specified by:

graph in interface org.apache.tinkerpop.gremlin.structure.Element

rdfId

com.bigdata.rdf.model.BigdataResource rdfId()

Return RDF value for element id (URI for Vertex, BNode for Edge and VertexProperty).

rdfLabel

org.openrdf.model.URI rdfLabel()

Return RDF literal for element label.

properties

<V> CloseableIterator<? extends org.apache.tinkerpop.gremlin.structure.Property<V>> properties(String... keys)

Strengthen return type to CloseableIterator. You MUST close this iterator when finished.

Specified by:

properties in interface org.apache.tinkerpop.gremlin.structure.Element

values

default <V> CloseableIterator<V> values(String... keys)

Strengthen return type to CloseableIterator. You MUST close this iterator when finished.

Specified by:

values in interface org.apache.tinkerpop.gremlin.structure.Element

keys

default Set<String> keys()

Provide safer default implementation (closes properties() iterator used to calculate keys).

Specified by:

keys in interface org.apache.tinkerpop.gremlin.structure.Element
