visitPath

public com.fasterxml.jackson.databind.JsonNode visitPath(PathExpressionParser.PathContext ctx)

Description copied from class: PathExpressionParserBaseVisitor

Visit a parse tree produced by the path labeled alternative in PathExpressionParser.expr().

The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.

Specified by:

visitPath in interface PathExpressionParserVisitor<com.fasterxml.jackson.databind.JsonNode>

Overrides:

visitPath in class PathExpressionParserBaseVisitor<com.fasterxml.jackson.databind.JsonNode>

Parameters:

ctx - the parse tree

Returns:

the visitor result
