Method Detail

getExtension

reactor.core.publisher.Mono<? extends EvaluationContextExtension> getExtension()

Return the EvaluationContextExtension to be consumed during the actual execution. It's strongly recommended to declare the most concrete type possible as return type of the implementation method. This will allow us to obtain the necessary metadata once and not for every evaluation.

Returns:

the resolved EvaluationContextExtension. Publishers emitting no value will be skipped.
