toEvaluator
public EvalOperator.ExpressionEvaluator.Factory toEvaluator(EvaluatorMapper.ToEvaluator toEvaluator) Description copied from interface:EvaluatorMapperConvert this into anEvalOperator.ExpressionEvaluator.Note for implementors: If you are implementing this function, you should call the passed-in lambda on your children, after doing any other manipulation (casting, etc.) necessary.
Note for Callers: If you are attempting to call this method, and you have an
Expressionand aLayout, you likely want to callEvalMapper.toEvaluator(org.elasticsearch.xpack.esql.core.expression.FoldContext, org.elasticsearch.xpack.esql.core.expression.Expression, org.elasticsearch.xpack.esql.planner.Layout)instead. On the other hand, if you already have something that looks like the parameter for this method, you should call this method with that function.Build an
EvalOperator.ExpressionEvaluator.Factoryfor the tree of expressions rooted at this node. This is only guaranteed to return a sensible evaluator if this node has a valid type. If this node is a subclass ofExpressionthen "valid type" means thatExpression.typeResolved()returns a non-error resolution. If Expression.typeResolved() returns an error then this method may throw. Or return an evaluator that produces garbage. Or return an evaluator that throws when run.- Specified by:

-
checkCompatibility
Check if the two input types are compatible for this operation. NOTE: this method should be consistent withVerifier.validateBinaryComparison(BinaryComparison)- Returns:
- TypeResolution.TYPE_RESOLVED iff the types are compatible. Otherwise, an appropriate type resolution error.

formatIncompatibleTypesMessage
-
translatable
Description copied from interface:TranslationAwareIndicates whether the expression can be translated or not. Usually checks whether the expression arguments are actual fields that exist in Lucene.- Specified by:
translatablein interfaceTranslationAware
-
asQuery
This method is responsible for pushing the ES|QL Binary Comparison operators into Lucene. It covers: In general, we are able to push these down when one of the arguments is a constant (i.e. is foldable). This class assumes that an earlier pass through the query has rearranged things so that the foldable value will be the right hand side input to the operation.- Specified by:
asQueryin interfaceTranslationAware
-
singleValueField
Description copied from interface:TranslationAware.SingleValueTranslationAwareReturns the field that only supports single-value semantics.- Specified by:
