Package ca.uhn.fhir.jpa.interceptor

Class CascadingDeleteInterceptor

java.lang.Object
ca.uhn.fhir.jpa.interceptor.CascadingDeleteInterceptor
public class CascadingDeleteInterceptor extends Object
Interceptor that allows for cascading deletes (deletes that resolve constraint issues).

For example, if DiagnosticReport/A has a reference to Observation/B it is not normally possible to delete Observation/B without first deleting DiagnosticReport/A. With this interceptor in place, it is.

When using this interceptor, client requests must include the parameter _cascade=delete on the DELETE URL in order to activate cascading delete, or include the request header X-Cascade-Delete: delete
