Persist Data

[muuki88]

Storing the data is a two step process.

Create a Data instance

You must find the correct sensor in the database first.

Sensor sensor = em.find(Sensor.class, "the-sensor-id");
Data data = new Data(from, to, sensor);
em.persist(data);

Helpfull classes:

• this testcases.
• PatientService

Copy files

After the sensor is persisted, you have to copy the files to the harddrive.

ISensor sensorInstance = ... // from sensorManager, not db instance!
Data data = new Data(from, to, sensor);
try (InputStream in = sensorInstance.getDataInputStream()) {
   // data.toPath() gets the harddrive path
   Files.copy(in, data.toPath());
}
