Constructor Summary

Constructors

Constructor	Description
GraphTraversalSourceVisitor(String traversalSourceName, GremlinAntlrToJava antlr)	Same as GraphTraversalSourceVisitor(GremlinAntlrToJava) but allows the traversal source name to be configured to something other than "g".
GraphTraversalSourceVisitor(GremlinAntlrToJava antlr)	Constructs the visitor and if the GremlinAntlrToJava has a GraphTraversalSource assigned to it, the visitor will prefer that "g" rather than creating a new one from the associated Graph instance.

Method Summary

Modifier and Type	Method	Description
GraphTraversalSource	visitTraversalSource(GremlinParser.TraversalSourceContext ctx)	Visit a parse tree produced by GremlinParser.traversalSource().

Constructor Details

GraphTraversalSourceVisitor

public GraphTraversalSourceVisitor(GremlinAntlrToJava antlr)

Constructs the visitor and if the GremlinAntlrToJava has a GraphTraversalSource assigned to it, the visitor will prefer that "g" rather than creating a new one from the associated Graph instance.

GraphTraversalSourceVisitor

public GraphTraversalSourceVisitor(String traversalSourceName,
 GremlinAntlrToJava antlr)

Same as GraphTraversalSourceVisitor(GremlinAntlrToJava) but allows the traversal source name to be configured to something other than "g".

Method Details

visitTraversalSource

public GraphTraversalSource visitTraversalSource(GremlinParser.TraversalSourceContext ctx)

Visit a parse tree produced by GremlinParser.traversalSource().

Specified by:

visitTraversalSource in interface GremlinVisitor<GraphTraversalSource>

Overrides:

visitTraversalSource in class DefaultGremlinBaseVisitor<GraphTraversalSource>

Parameters:

ctx - the parse tree

Returns:

the visitor result
