All Implemented Interfaces:
Closeable, AutoCloseable, ExpressionEvaluator, org.elasticsearch.core.Releasable
public record BooleanLogicExpressionEvaluator(BinaryLogic bl, ExpressionEvaluator leftEval, ExpressionEvaluator rightEval) extends Record implements ExpressionEvaluator
Evaluator for the three-valued boolean expressions. We can't generate these with the Evaluator annotation because that always implements viral null. And three-valued boolean expressions don't. false AND null is false and true OR null is true.

      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

      Parameters:
      o - the object with which to compare
      Returns:

      Returns:
      the value of the bl record component

    • leftEval

      public ExpressionEvaluator leftEval()
      Returns the value of the leftEval record component.
      Returns:
      the value of the leftEval record component

    • rightEval

      public ExpressionEvaluator rightEval()
      Returns the value of the rightEval record component.
      Returns:
      the value of the rightEval record component
