SimpleScriptedLookupService¶

Description¶

Allows the user to provide a scripted LookupService instance in order to enrich records from an incoming flow file. The script is expected to return an optional string value rather than an arbitrary object (record, e.g.). Also the scripted lookup service should implement StringLookupService, otherwise the getValueType() method must be implemented even though it will be ignored, as SimpleScriptedLookupService returns String as the value type on the script’s behalf.
