Class OQLBaseVisitor<T>

  • Type Parameters:
    T - The return type of the visit operation. Use Void for operations with no return type.
    All Implemented Interfaces:
    org.antlr.v4.runtime.tree.ParseTreeVisitor<T>, OQLVisitor<T>
    Direct Known Subclasses:
    OQLFilterVisitor
    public class OQLBaseVisitor<T>
extends org.antlr.v4.runtime.tree.AbstractParseTreeVisitor<T>
implements OQLVisitor<T>
    This class provides an empty implementation of OQLVisitor, which can be extended to create a visitor which only needs to handle a subset of the available methods.

    • Method Detail

      • visitParse

        public T visitParse​(OQLParser.ParseContext ctx)
        Visit a parse tree produced by OQLParser.parse().

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

        Specified by:
        visitParse in interface OQLVisitor<T>
        Parameters:
        ctx - the parse tree
        Returns:
        the visitor result

      • visitNotExpr

        public T visitNotExpr​(OQLParser.NotExprContext ctx)
        Visit a parse tree produced by the notExpr labeled alternative in OQLParser.expr().

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

        Specified by:
        visitNotExpr in interface OQLVisitor<T>
        Parameters:
        ctx - the parse tree
        Returns:
        the visitor result

      • visitAtomExpr

        public T visitAtomExpr​(OQLParser.AtomExprContext ctx)
        Visit a parse tree produced by the atomExpr labeled alternative in OQLParser.expr().

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

        Specified by:
        visitAtomExpr in interface OQLVisitor<T>
        Parameters:
        ctx - the parse tree
        Returns:
        the visitor result

      • visitOrExpr

        public T visitOrExpr​(OQLParser.OrExprContext ctx)
        Visit a parse tree produced by the orExpr labeled alternative in OQLParser.expr().

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

        Specified by:
        visitOrExpr in interface OQLVisitor<T>
        Parameters:
        ctx - the parse tree
        Returns:
        the visitor result

      • visitEqualityExpr

        public T visitEqualityExpr​(OQLParser.EqualityExprContext ctx)
        Visit a parse tree produced by the equalityExpr labeled alternative in OQLParser.expr().

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

        Specified by:
        visitEqualityExpr in interface OQLVisitor<T>
        Parameters:
        ctx - the parse tree
        Returns:
        the visitor result

      • visitAndExpr
