Class ValidationRSQLVisitor

java.lang.Object
in.co.akshitbansal.springwebquery.ValidationRSQLVisitor
All Implemented Interfaces:
cz.jirutka.rsql.parser.ast.RSQLVisitor<Void,NodeMetadata>
Direct Known Subclasses:
DTOValidationRSQLVisitor, EntityValidationRSQLVisitor
public abstract class ValidationRSQLVisitor extends Object implements cz.jirutka.rsql.parser.ast.RSQLVisitor<Void,NodeMetadata>
Base RSQL AST visitor that enforces logical operator and depth constraints.

Subclasses are responsible for validating ComparisonNode details, while this base class handles:

  • Disallowing AND/OR nodes based on configuration.
  • Ensuring the AST does not exceed the configured maximum depth.

    Modifier and Type
    Method
    Description
    protected abstract void
    validateComparisonNode(cz.jirutka.rsql.parser.ast.ComparisonNode node)
    Validates a comparison node for field/operator correctness.
    protected void
    validateNode(cz.jirutka.rsql.parser.ast.Node node, NodeMetadata metadata)
    Validates logical operator usage and depth constraints for the given node.
    Void
    visit(cz.jirutka.rsql.parser.ast.AndNode node, NodeMetadata metadata)
    Validates AND nodes and recursively visits child nodes.
    Void
    visit(cz.jirutka.rsql.parser.ast.ComparisonNode node, NodeMetadata metadata)
    Validates comparison nodes and delegates field/operator validation.
    Void
    visit(cz.jirutka.rsql.parser.ast.OrNode node, NodeMetadata metadata)
    Validates OR nodes and recursively visits child nodes.

    • validateComparisonNode

      protected abstract void validateComparisonNode(cz.jirutka.rsql.parser.ast.ComparisonNode node)
      Validates a comparison node for field/operator correctness.
      Parameters:
      node - comparison node to validate

    • validateNode

      protected void validateNode(cz.jirutka.rsql.parser.ast.Node node, NodeMetadata metadata)
      Validates logical operator usage and depth constraints for the given node.
      Parameters:
      node - node to validate
      metadata - node metadata including current depth
      Throws:
      QueryValidationException - if an operator is disallowed or the depth exceeds the limit
