org.elasticsearch.xpack.esql.core.expression.Attribute.IdIgnoringWrapper
Enclosing class:
Attribute
public static record Attribute.IdIgnoringWrapper(Attribute inner) extends Record
A wrapper class where equality of the contained attribute ignores the NamedExpression.id(). Useful when we want to create new attributes and want to avoid duplicates. Because we assign unique ids on creation, a normal equality check would always fail when we create the "same" attribute again.

C.f. AttributeMap (and its contained wrapper class) which does the exact opposite: ignores everything but the id by using Attribute.semanticEquals(Expression).

      Returns:
      a hash code value for this object

    • toString

      public final String toString()
