How to pass instance of the dependency from a same module in Toothpick?

Question

Suppose I have a module in which one binding depends on another:

class MyModule : Module(){
  init {
    bind(SettingsStorage::class.java).to(PreferencesBasedSettingsStorage::class.java)
    // how to use createOkHttpClient here? 
    // how to get instance of SettingsStorage to pass to it?
    bind(OkHttpClient::class.java).to?(???)
  }

  private fun createOkHttpClient(settingsStorage: SettingsStorage): OkHttpClient {
    return OkHttpClient.Builder()
      .addNetworkInterceptor(MyInterceptor(settingsStorage))
      .build()
  } 
}

Here I can create OkHttpClient only having an instance of another binding, namely SettingsStorage. But how to do that?

Currently I see no way to get instance of SettingsStorage binding inside a module to pass it to createOkHttpClient()

In Dagger I would've simply created two provider methods with appropriate arguments like

fun provideSessionStorage(/*...*/): SessionStorage { /* ... */ }

fun provideOkHttpclient(sessionStorage: SessionStorage): OkHttpClient {
   return OkHttpClient.Builder()
    .addNetworkInterceptor(MyInterceptor(settingsStorage))
    .build()
}

And it would figure all out by itself and passed appropriate instance of sessionStorage to a second provider function.

How to achieve the same inside a Toothpick module?

Answer 1

It's simple with TP:

class MyModule : Module(){
  init {
    bind(SettingsStorage::class.java).to(PreferencesBasedSettingsStorage::class.java)
    // how to use createOkHttpClient here? 
    // how to get instance of SettingsStorage to pass to it?
    bind(OkHttpClient::class.java).toProvider(OkHttpClientProvider::class)
  }
}

and then you define a provider (sorry I don't use Kotlin):

class OkHttpClientProvider implements Provider<OkHttpClient> {
  @Inject SettingsStorage settingsStorage;
  public OkHttpClient get() {
     return OkHttpClient.Builder()
      .addNetworkInterceptor(MyInterceptor(settingsStorage))
      .build()
  }
}

Your provider will use the first binding to provide the OkHttp client.
