Method Summary

Modifier and Type	Method and Description
Translator.ParametrizedFlavorBuilder<org.apache.tinkerpop.gremlin.process.traversal.Bytecode,org.apache.tinkerpop.gremlin.process.traversal.P>	bytecode() Builds a Translator that translates Cypher queries to Gremlin bytecode.
<T,P> Translator.FlavorBuilder<T,P>	custom(GremlinSteps<T,P> steps, GremlinPredicates<P> predicates, GremlinBindings parameters) Builds a Translator that translates Cypher queries to custom format via the provided steps and predicates implementation.
Translator.ParametrizedFlavorBuilder<java.lang.String,GroovyPredicate>	gremlinGroovy() Builds a Translator that translates Cypher queries to strings of Gremlin-Groovy.
Translator.FlavorBuilder<org.apache.tinkerpop.gremlin.process.traversal.dsl.graph.GraphTraversal,org.apache.tinkerpop.gremlin.process.traversal.P>	traversal() Builds a Translator that translates Cypher queries to Gremlin anonymous GraphTraversal.
