Re: HL7/Using terser in Bean

[Quinn Stevenson <qu...@pronoia-solutions.com>]

If I understand what you’re asking, you could use a HAPI Terser (https://hapifhir.github.io/hapi-hl7v2/base/apidocs/ca/uhn/hl7v2/util/Terser.html <https://hapifhir.github.io/hapi-hl7v2/base/apidocs/ca/uhn/hl7v2/util/Terser.html>) in your bean.
