VAlgoLangParserVisitor

class VAlgoLangParserVisitor : VAlgoLangParserBaseVisitor<ASTNode>

VAlgoLang parser visitor

This class implements the VAlgoLangParserBaseVisitor abstract class returning an abstract syntax tree(AST). Here it traverses the concrete syntax tree (parse tree) to perform semantic analysis, construct the line to statement node map (lineNumberNodeMap) and the AST.
