Type Members

  1. class CypherAst extends AnyRef

    Parsed Cypher AST wrapper that can transform it in a suitable format for executing a Gremlin traversal.

  2. class EmptyParserContext extends BaseContext
  3. trait GremlinBindings extends AnyRef

    This abstracts Gremlin query bindings translation.

    This abstracts Gremlin query bindings translation. For some context, see Gremlin-Python Bindings.

  4. trait GremlinPredicates[P] extends AnyRef

    Gremlin org.apache.tinkerpop.gremlin.process.traversal.P predicate abstraction.

    Gremlin org.apache.tinkerpop.gremlin.process.traversal.P predicate abstraction. For DSL details, see A Note on Predicates.

  5. trait GremlinSteps[T, P] extends AnyRef

    Gremlin org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.GraphTraversal DSL wrapper.

    Gremlin org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.GraphTraversal DSL wrapper. For DSL details, see Graph Traversal Steps.

    Implementations define a translation target that can be built with org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.GraphTraversal steps.

    Note: steps are expected to be side-effecting, thus, unsuitable for use in immutable contexts.

  6. final class GroovyIdentifiers extends AnyRef
  7. final class ReturnProperties extends AnyRef
  8. sealed abstract final class StatementOption extends Enum[StatementOption]
  9. class TranslationFacade extends AnyRef

    Cypher to Gremlin translation facade.

    Cypher to Gremlin translation facade.

    Basic usage example: 

    
String cypher = "MATCH (p:Person) WHERE p.age > 25 RETURN p.name";
TranslationFacade cfog = new TranslationFacade();
String gremlin = cfog.toGremlinGroovy(cypher);
