OpenMRS Encounter is a point in time. If a FHIR Encounter spans a period of time (e.g., days), it would be an OpenMRS Visit. If a FHIR Encounter has observations linked to it, it's an OpenMRS Encounter

Synchronizing objects via FHIR

To add another object to FHIR synchronization, you must implement the FHIR Strategy Pattern

...

Code Block

package org.openmrs.module.fhir.api.strategies.objectname;

import org.hl7.fhir.dstu3.model.Objectname;

public interface GenericObjectnameStrategy {

   Objectname getObjectname(String uuid);

   void deleteObjectname(String uuid);

   Objectname updateObjectname(String uuid, Objectname objectname);

   Objectname createObjectname(Objectname objectname);
}

...

Code Block

package org.openmrs.module.fhir.api.strategies.objectname;

import org.openmrs.api.context.Context;
import org.openmrs.module.fhir.api.util.FHIRUtils;

public class ObjectNameStrategyUtil {

   public static GenericObjectNameStrategy getObjectNameStrategy() {
      String strategy = FHIRUtils.getObjectNameStrategy();

      return strategy == null ? new ObjectNameStrategy() :
            Context.getRegisteredComponent(strategy, GenericObjectNameStrategy.class);
   }
}

Strategy Util class will be called in ObjectNameServiceImpl class

Code Block

package org.openmrs.module.fhir.api.impl;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.hl7.fhir.dstu3.model.ObjectName;
import org.openmrs.api.impl.BaseOpenmrsService;
import org.openmrs.module.fhir.api.ObjectNameService;
import org.openmrs.module.fhir.api.db.FHIRDAO;
import org.openmrs.module.fhir.api.strategies.objectname.ObjectNameStrategyUtil;

public class ObjectNameServiceImpl extends BaseOpenmrsService implements ObjectNameService {

   protected final Log log = LogFactory.getLog(this.getClass());

   private FHIRDAO dao;

   /**
    * @return the dao
    */
   public FHIRDAO getDao() {
      return dao;
   }

   /**
    * @param dao the dao to set
    */
   public void setDao(FHIRDAO dao) {
      this.dao = dao;
   }

   @Override
   public ObjectName getObjectName(String uuid) {
      return ObjectNameStrageryUtil.getObjectNameStrategy().getObjectName(uuid);
   }

   @Override
   public void deleteObjectName(String uuid) {
      ObjectNameStrageryUtil.getObjectNameStrategy().deleteObjectName(uuid);
   }

   @Override
   public ObjectName updateObjectName(String uuid, ObjectName objectName) {
      return ObjectNameStrategyUtil.getObjectName().updateObjectName(uuid, objectName);
   }

   @Override
   public ObjectName createObjectName(ObjectName objectName) {
      return ObjectNameStrategyUtil.getObjectNameStrategy().createObjectName(ObjectName);
   }
}

Which should implement an ObjectNameService interface

Code Block


package org.openmrs.module.fhir.api;

import org.hl7.fhir.dstu3.model.ObjectName;
import org.openmrs.api.OpenmrsService;
import org.springframework.transaction.annotation.Transactional;

@Transactional
public interface ObjectNameService extends OpenmrsService {

   /**
    * Get object by id
    *
    * @param uuid The uuid of object
    * @return ObjectName fhir resource
    */
   ObjectName getObjectName(String uuid);

   /**
    * Delete object by id
    *
    * @param uuid The uuid of object
    */
   void deleteObjectName(String uuid);

   /**
    * Update object
    *
    * @param uuid          The uuid of object
    * @param objectName representation of object fhir resource
    */
   ObjectName updateObjectName(String uuid, ObjectName objectName);

   /**
    * Create object
    *
    * @param objectName the object to create
    */
   ObjectName createObjectName(ObjectName objectName);
}
