All Implemented Interfaces:
QueryConstants
public class RelationQueryNode extends NAryQueryNode<QueryNode> implements QueryConstants
Implements a query node that defines property value relation.

  • Field Details

    • STAR_NAME_TEST

      public static final Name STAR_NAME_TEST
      Acts as an synthetic placeholder for a location step that matches any name. This is required because a JCR path does not allow a Name with a single '*' (star) character.

  • Method Details

    • accept

      public Object accept(QueryNodeVisitor visitor, Object data) throws RepositoryException
      Accepts a QueryNodeVisitor and calls the appropriate visit method on the visitor depending on the concrete implementation of this QueryNode.
      Specified by:
      accept in class QueryNode
      Parameters:
      visitor - the visitor to call back.
      data - arbitrary data for the visitor.
      Returns:
      the return value of the visitor.visit() call.
      Throws:
      RepositoryException
