Builder

Configuration builder for StdioServerTransport. Used via the StdioServerTransport(input, output) { ... } factory; the I/O endpoints are supplied positionally, while scope, handlerDispatcher, and ioDispatcher are configurable inside the block.

Example:

StdioServerTransport(input, output) {
    scope = CoroutineScope(SupervisorJob() + Dispatchers.Default)
    handlerDispatcher = myHandlerDispatcher
    ioDispatcher = Dispatchers.IO
}

Properties

handlerDispatcher

var handlerDispatcher: CoroutineDispatcher

Dispatcher for invoking the registered message handler. Defaults to Dispatchers.Default.

ioDispatcher

var ioDispatcher: CoroutineDispatcher

Dispatcher for the reader and writer coroutines. Must allow at least two threads to run concurrently so the reader and writer don't block each other. The default is a two-thread view of the platform I/O dispatcher (IODispatcher.limitedParallelism(2)); pass a different value to share or isolate I/O threads with the rest of your application.

scope

var scope: CoroutineScope?

Optional caller-supplied CoroutineScope. When non-null, the transport's pipeline coroutines run as children of this scope and the transport does not tear it down on close. When null, the transport creates and owns an internal scope.
