mapper

A simple collection of interfaces for mapping between objects.

Using the library

This library contains two simple mapping interfaces: UniDirectionalMapper and BiDirectionalMapper. There is also a typealias called Mapper for the UniDirectionalMapper interface.

Unidirectional Mapping

class MyMapper : Mapper<Model, ViewModel> {

    override fun map(value: Model): ViewModel = ...
}

...

// Using the Mapper
val viewModel = mapper.map(value = myModel)

// Or in a Flow
getFlowOfModels()
    .map(mapper::map)

BiDirectional Mapping

class MyMapper : BiDirectionalMapper<InModel, OutModel> {

    override fun mapIn(value: InModel): OutModel = ...

    override fun mapOut(value: OutModel): InModel = ...
}

// Using the Mapper
val mapOut = mapper.mapIn(value = mapIn)
val mapInAgain = mapper.mapOut(value = mapOut)

// Or in a Flow
getFlowOfModels()
    .map(mapper::mapIn)
