Interface AqlQueryParsingPostProcessor

All Superinterfaces:

org.springframework.core.Ordered

All Known Implementing Classes:

AqlEhrPathPostProcessor, AqlFromEhrOptimisationPostProcessor, AqlLimitPostProcessor, AqlParameterPostProcessor, AqlQueryFeatureCheck

public interface AqlQueryParsingPostProcessor
extends org.springframework.core.Ordered

Used for modifications of the parsed AQL query directly after parsing. All Spring beans implementing this interface will be picked up by AqlQueryService.

Specifying the Order is required since in-place modifications may affect each other. Having multiple beans of this type with the same order value may produce inconsistent results.
