    The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.
    
    Specified by:
    
    visitForwardAll in interface OpenGaussStatementVisitor<ASTNode>
    
    Overrides:
    
    visitForwardAll in class OpenGaussStatementBaseVisitor<ASTNode>
    
    Parameters:
    
    ctx - the parse tree
    
    Returns:
    
    the visitor result
  - visitBackward
```
public ASTNode visitBackward(OpenGaussStatementParser.BackwardContext ctx)
```
    Description copied from class: OpenGaussStatementBaseVisitor
    
    Visit a parse tree produced by the backward labeled alternative in OpenGaussStatementParser.direction().
    The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.
    
    Specified by:
    
    visitBackward in interface OpenGaussStatementVisitor<ASTNode>
    
    Overrides:
    
    visitBackward in class OpenGaussStatementBaseVisitor<ASTNode>
    
    Parameters:
    
    ctx - the parse tree
    
    Returns:
    
    the visitor result
  - visitBackwardCount
```
public ASTNode visitBackwardCount(OpenGaussStatementParser.BackwardCountContext ctx)

    Description copied from class: OpenGaussStatementBaseVisitor
    
    Visit a parse tree produced by the backwardCount labeled alternative in OpenGaussStatementParser.direction().
    The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.
    
    Specified by:
    
    visitBackwardCount in interface OpenGaussStatementVisitor<ASTNode>
    
    Overrides:
    
    visitBackwardCount in class OpenGaussStatementBaseVisitor<ASTNode>
    
    Parameters:
    
    ctx - the parse tree
    
    Returns:
    
    the visitor result
  - visitBackwardAll
```
public ASTNode visitBackwardAll(OpenGaussStatementParser.BackwardAllContext ctx)
```
    Description copied from class: OpenGaussStatementBaseVisitor
    
    Visit a parse tree produced by the backwardAll labeled alternative in OpenGaussStatementParser.direction().
    The default implementation returns the result of calling AbstractParseTreeVisitor.visitChildren(org.antlr.v4.runtime.tree.RuleNode) on ctx.
    
    Specified by:
    
    visitBackwardAll in interface OpenGaussStatementVisitor<ASTNode>
    
    Overrides:
    
    visitBackwardAll in class OpenGaussStatementBaseVisitor<ASTNode>
