the service and the manager are services

they are like utils classes

for example :

package fstn.vertxFlow.config.manager

import io.vertx.rxjava.core.Vertx
import io.vertx.rxjava.core.buffer.Buffer
import rx.Observable


/**
 * Use to read or write bpmn flow file
 * @author fstn
 */
class BpmnManager {

    fun get(flowName:String): Observable<Buffer> {
        return Vertx.vertx().fileSystem()
                .rxReadFile(“$flowName.bpmn”)
                .doOnError { throw UnableToReadConfigurationException(flowName) }
                .toObservable()
    }

    fun set(flowName:String,flowContent:String): Observable<Void> {
        return Vertx.vertx().fileSystem()
                .rxWriteFile(“$flowName.bpmn”, Buffer.buffer(flowContent))
                .doOnError { throw UnableToWriteConfigurationException(flowName) }
                .toObservable()
    }

    class UnableToWriteConfigurationException(flowName: String) : RuntimeException(flowName)
    class UnableToReadConfigurationException(flowName: String) : RuntimeException(flowName)
}

and the set write into the file

should I use a class or an object ?

or a companion object

alternatively you could just use a bunch of package-scoped functions, as there doesn't seem to be any persisted state here

but Intellij doesn’t import automaticaly package of function

so it’s very boring

that’s why I prefere to use classes or objects 😂

Mine doesn’t want to

i guess the function names are too short for the intellisense to kick in

I use slightly longer names, and the autocoplete starts suggesting them
