JsonWriterPublisher

org.eso.ias.dasu.publisher.JsonWriterPublisher
class JsonWriterPublisher(val writer: Writer) extends OutputPublisher

The publisher of IASValues produced by the DASU in a JSON-like format.

The JSON output is composed of records of IASV-n JSON string of the IASValues like IASV1 IASV2 IASV3

The format of a true JSON file is [ IASV1, IASV2, IASV3,...]

The ideal solution would be to let Jackson2 write the array of IASValues passing one item at a time but, browsing the net, it does not seem as easy as I expected.

Value parameters

filePath

the path of the JSON file to write
