The goal is to replace `Fn` with more standard or efficient functional representations where applicable. + +#### Migration Instructions + +The goal of this migration is to replace the use of the `Fn` class with standard Kotlin functional interfaces (lambdas) in the `lib` module while maintaining serialization compatibility in the `exe` module. + +##### Step 1: Update the `lib` module + +Modify the classes in the `lib` module to use standard Kotlin functional interfaces instead of `Fn`. + +- Change constructor parameters and properties from `Fn` to `(T) -> R` (or appropriate functional type). +- Update the implementation to call the lambda directly instead of using `.apply()`. +- Keep the `BeanParams` classes and other structures, but update their properties to use lambdas. +- If the `BeanParams` had a custom serializer within the `lib` module, it should be moved or replaced by a more general approach, as lambdas cannot be directly serialized by `kotlinx.serialization` without extra help. + +Example (`InputParams` in `io.wavebeans.lib.io.FunctionInput`): +```kotlin +// Before +class InputParams( + val generator: Fn, T?>, + val sampleRate: Float? = null +) : BeanParams + +// After +class InputParams( + val generator: (Long, Float) -> T?, + val sampleRate: Float? = null +) : BeanParams +``` + +##### Step 2: Create a custom serializer in the `exe` module + +Since lambdas are not serializable, create a custom `KSerializer` in the `exe` module (typically under `io.wavebeans.execution.serializer`) that wraps the lambda into an `Fn` during serialization and unwraps it during deserialization. + +- The `serialize` method should use `io.wavebeans.lib.wrap()` to convert the lambda to an `Fn`. +- The `deserialize` method should decode the `Fn` and then return a lambda that calls `fn.apply()`. +- Use `FnSerializer` to handle the actual serialization/deserialization of the wrapped `Fn`. + +Example (`InputParamsSerializer` in `io.wavebeans.execution.serializer`): +```kotlin +object InputParamsSerializer : KSerializer> { + override val descriptor: SerialDescriptor = buildClassSerialDescriptor(InputParams::class.className()) { + element("generateFn", FnSerializer.descriptor) + element("sampleRate", Float.serializer().nullable.descriptor) + } + + override fun deserialize(decoder: Decoder): InputParams<*> { + return decoder.decodeStructure(descriptor) { + var sampleRate: Float? = null + lateinit var func: Fn, Any?> + loop@ while (true) { + when (val i = decodeElementIndex(descriptor)) { + CompositeDecoder.DECODE_DONE -> break@loop + 0 -> func = decodeSerializableElement(descriptor, i, FnSerializer) as Fn, Any?> + 1 -> sampleRate = decodeNullableSerializableElement(descriptor, i, Float.serializer().nullable) + else -> throw SerializationException("Unknown index $i") + } + } + InputParams({ a, b -> func.apply(a to b) }, sampleRate) + } + } + + override fun serialize(encoder: Encoder, value: InputParams<*>) { + encoder.encodeStructure(descriptor) { + encodeSerializableElement(descriptor, 0, FnSerializer, wrap(value.generator)) + encodeNullableSerializableElement(descriptor, 1, Float.serializer().nullable, value.sampleRate) + } + } +} +``` + +##### Step 3: Register the serializer in `SerializationUtils.kt` + +Update `io.wavebeans.execution.SerializationUtils.kt` to register the new serializer in the `beanParams()` method.

The file system type is specified via URL in scheme place, i.e. to specify local file use `file://` on scheme place and then path to the file like `/my/directory/file.txt`, so the URL of the file would look like `file:///my/directory/file.txt`. By default only [local file](#local-file-system) is accessible but you can always add more. Currently you would need to register file system driver yourself if it's different from local file system. To do that call appropriate method on `io.wavebeans.fs.core.WbFileDriver` object: ```kotlin // register driver, you can only do that once for specific scheme WbFileDriver.registerDriver("myscheme", MyDriverImplementation()) // unregister driver, so you can register another one if you need WbFileDriver.unregisterDriver("myscheme") ``` Driver implements the `io.wavebeans.fs.core.WbFileDriver` interface. Usually you won't need to access file system directly, you would always use methods responsible to call the file system themselves, i.e. `wav("file:///my/directory/file.wav")`. But here some tips if you ever need to: ```kotlin // instantiate the driver of certain type val fileDriver = WbFileDriver.instance("file") // create a temporary file, it'll generate random filler to make sure the file is new val temporaryFile = fileDriver.createTemporaryWbFile("temp", "txt") // create a file pointer by URI val file = fileDriver.createWbFile(URI("file:///my/directory/file.txt")) // shortcut to create the file pointer of certain scheme /*val file = */WbFileDriver.createFile(URI("file:///my/directory/file.txt")) // check if file exists file.exists() // delete file file.delete() // create output stream to write file content file.createWbFileOutputStream() // create input stream to read file content file.createWbFileInputStream() ``` Overall follow code-level API documentation. ## Local File System Local File System is supported by default and you don't need to do something special in order to use it. Just be aware, that in [distributed mode](../exe/readme.md#distributed-mode) it won't work as expected. To use the local file system, specify the `file` scheme in the URI. Also you need to be aware that only absolute path is supported at this moment, so every time you need to specify the path from the root. It might be handy to use `java.io.File` and resolve the absolute path using its API: ```kotlin val inputFile = File("input.wav") val input = wave("file://${inputFile.absolutePath}") ``` ## Dropbox File System DropBox File System allows work with files in your DropBox folder. It's a little tricky to configure and requires a little more effort, but overall quite handy. To start working with your DropBox account you'll need to go to its Developer console and create the key: 1. Go to Dropbox App Console: [https://www.dropbox.com/developers/apps](https://www.dropbox.com/developers/apps) 2. Click "Create app" button. 3. Choose an API: "Dropbox API". 4. Choose the type of access: "Full Dropbox" or "App folder". Doesn't matter. Though the second option is a little safer overall, but it is up to you and your requirements. 5. Name your app, remember the name you've given. Later on it'll be used as "Client Identifier". 6. Hit "Create app" button. 7. On "Settings" tab generate a new "Access token" and copy it. You'll need it later. Dropbox filesystem distributed as a separate library, so add it as a dependency, i.e. for gradle: ```groovy dependencies { implementation "io.wavebeans:filesystems-dropbox:$wavebeans_version" } ``` Then you need to configure the driver. It'll automatically reigster itself under `dropbox` scheme: ```kotlin DropboxWbFileDriver.configure( "Client identifier", "Access Token" ) ``` After that action you may start using files via `dropbox` scheme: ```kotlin val input = wave("dropbox:///folder/input.wav") ``` If you want to register the driver yourself, for instance under different name, or use a few drivers at a time, you may just instantiate the object of class `io.wavebeans.fs.dropbox.DropboxWbFileDriver` and register it via call to `WbFileDriver.registerDriver()`. ### Production usage The approach provided above is handy for running server for sole use or testing, however for multi-user or user-agnostic deployment can't be used. To get a proper access token you would need to follow the OAuth flow which is perfectly explained in [Dropox developer's documentation](https://www.dropbox.com/lp/developers/reference/oauth-guide). Though here are some snippets based on Java Dropbox SDK `com.dropbox.core:dropbox-core-sdk:3.1.4`. 1. Initialize auth client. ```kotlin val auth = DbxWebAuth( DbxRequestConfig(""), DbxAppInfo("", "") ) ``` 2. You would need to create a session storage, you may use `com.dropbox.core.DbxStandardSessionStore` if you're running some servlet container web server like Tomcat or Jetty. But here for the sake of simplicity we'll use some simple implementation based on file: ```kotlin val sessionStore = object : DbxSessionStore { private val csrf = File("/some/directory/csrf.code") override fun clear() { csrf.createNewFile() } override fun get(): String = csrf.readText() override fun set(value: String) { csrf.createNewFile() csrf.writeText(value) } } ``` 3. Define a return URL, we'll need it exactly in that form in two places. Specify any path or any set of parameters you require. Also don't forget to register it in Dropbox App console. ```kotlin val ruri = "http://localhost:8888" ``` 4. Generate authorization URL and redirect user there. ```kotlin val uri = auth.authorize(DbxWebAuth.Request.newBuilder() .withRedirectUri(ruri, sessionStore) .build()) redirectTo(uri) ``` 5. When user returned back on your return URL, in the handler extract `state` and `code` out of query parameters and request for access token, which later on you'll use to access the Dropbox API. ```kotlin val state = queryParameters["state"] val code = queryParameters["code"] val accessToken = auth.finishFromRedirect( ruri, sessionStore, mapOf( "state" to arrayOf(state), "code" to arrayOf(code) ) ).accessToken ``` 6.

For transferring all values should be serialized into strings. - -There is an API for handling primitive types and their collections: +To read parameters within the lambda: ```kotlin -FnInitParameters() - .add("double", 1.0) // will be stored as double string "1.0" - .add("int", 123) // will be stored as int string "123" - .add("string", "some_string") // will be stored as is - .addStrings("strings", listOf("string1", "string2")) // will be stored as comma-separated strings "string1,string2" - .addDoubles("doubles", listOf(1.0, 2.0)) // will be stored as comma separated double string "1.0,2.0" - .addInts("ints", listOf(1, 2)) // will be stored as comma separated double string "1,2" +val d = parameters.double("double") +val i = parameters.intOrNull("int") +val s = parameters.strings("strings") +val obj = parameters.obj("complex") { MyObj.deserialize(it) } ``` -And it works similar wth floats and longs. -To store an object or any other type you would need to specify the stringifier that converts an object to a string. +### Maintaining State + +If your function needs a complex object that should be initialized only once (e.g., a heavy-weight processor or a non-serializable object), use the `state` method: ```kotlin -FnInitParameters() - .addObj("timeUnit", TimeUnit.MILLISECONDS) { it.name } // stringifying simple but different type - .addObj("pairOfLongs", Pair(1L, 2L)) { "${it.first}:${it.second}" } // stringifying complex type - .addObj("myListOfInts", listOf(1, 2, 3)) { it.joinToString(",") { it.toString() } } // stringifying collections your way +stream.map(executionScope { add("config", "...") }) { sample -> + val processor = state("myProcessor") { + val config = parameters.string("config") + HeavyProcessor(config) + } + processor.process(sample) +} ``` -As you probably noticed, API of parameters allows you to specify parameters one by one without storing the result in interim variable, so these coding styles has same result: +The `state` method ensures that the initialization block is called only once per execution unit (pod) and the result is cached for subsequent calls. -```kotlin -// defining parameters with storing in interim variable -val p = FnInitParameters() -p.add("timeValue", 1) -p.addObj("timeUnit", TimeUnit.MILLISECONDS) { it.name } -MyFn(p) - -// specifying parameters sequentially -MyFn(FnInitParameters() - .add("timeValue", 1) - .addObj("timeUnit", TimeUnit.MILLISECONDS) { it.name } -) -``` +### Why not just use closures? -To read parameters you would need to specify explicitly what you want get. Keep in mind, some of the methods may work for different values stored as they are interchangeable in some sense (i.e. you can get int as double). All parameters are nullable, but you can ask for non-nullable value, you would need to specify it explicitly. +In local or multi-threaded mode, you can use regular Kotlin closures: -Primitive types: ```kotlin -val double = parameters.double("double") // get non-nullable double value -val doubleOrNull = parameters.doubleOrNull("double") // get nullable double value -val doubles = parameters.doubles("doubles") // get non-nullable list of doubles -val doublesOrNull = parameters.doublesOrNull("doubles") // get nullable list of doubles +val factor = 2.0 +stream.map { it * factor } // Works in local mode ``` -It works similar for float, int and long. -For getting an object, similar way to specifying stringifier you would need to specify objectifier that parses the value. You may get an object as nullable or not as well: -```kotlin -val timeUnit = parameters.obj("timeUnit") { TimeUnit.valueOf(it) } -val pairOfLongs = parameters.objOrNull("pairOfLongs") { - val (first, second) = it.split(":").map { it.toLong() }.take(2) - Pair(first, second) -} -val myListOfInts = parameters.obj("myListOfInts") { it.split(",").map { it.toInt() } } -``` +However, **this will fail in distributed mode**. The execution engine needs to serialize the lambda and send it to worker nodes. Kotlin lambdas do not automatically serialize their captured variables unless they are specifically designed to do so and all captured objects are serializable. `ExecutionScope` provides a robust, framework-supported way to handle this. diff --git a/docs/user/api/inputs/function-as-input.md b/docs/user/api/inputs/function-as-input.md index eb5689e8..6a20befe 100644 --- a/docs/user/api/inputs/function-as-input.md +++ b/docs/user/api/inputs/function-as-input.md @@ -43,33 +43,17 @@ Note: here we've used helper function `sampleOf()` which converts any numeric ty **Parameterized function** -If you want to create an input that expect some parameters or data during runtime, you can define a class.
