Class OverridePathBasedReferentialIntegrityForDeletesInterceptor

java.lang.Object

ca.uhn.fhir.jpa.interceptor.OverridePathBasedReferentialIntegrityForDeletesInterceptor

public class OverridePathBasedReferentialIntegrityForDeletesInterceptor
extends Object

This JPA interceptor can be configured with a collection of FHIRPath expressions, and will disable referential integrity for target resources at those paths.

For example, suppose this interceptor is configured with a path of AuditEvent.entity.what, and an AuditEvent resource exists in the repository that has a reference in that path to resource Patient/123. Normally this reference would prevent the Patient resource from being deleted unless the AuditEvent was first deleted as well (or a cascading delete was used). With this interceptor in place, the Patient resource could be deleted, and the AuditEvent would remain intact.
