Package avail.io

Types

An AvailClient is an accessor of Avail.

class ConsoleInputChannel(stream: InputStream) : TextInputChannel

A ConsoleInputChannel provides a faux asynchronous interface to a synchronous input stream. The reader must supply UTF-8 encoded characters.

ConsoleOutputChannel

class ConsoleOutputChannel(stream: PrintStream) : TextOutputChannel

A ConsoleOutputChannel provides a faux asynchronous interface to a synchronous output stream.

IOSystem

class IOSystem

This aggregates socket and file I/O information and behavior specific to an AvailRuntime.

NybbleOutputStream

class NybbleOutputStream @JvmOverloads constructor(size: Int = 0) : ByteArrayOutputStream

NybbleOutputStream is a ByteArrayOutputStream that enforces that only nybbles — values in [0..15] — are written.

ProcessInputChannel

class ProcessInputChannel(stream: InputStream) : TextInputChannel

A ProcessInputChannel provides a faux asynchronous interface to a synchronous process input stream. The reader must supply UTF-8 encoded characters.

ProcessOutputChannel

class ProcessOutputChannel(stream: PrintStream) : TextOutputChannel

A ProcessInputChannel provides a faux asynchronous interface to a synchronous output stream.

SimpleCompletionHandler

class SimpleCompletionHandler<V>(completed: SimpleCompletionHandler.Companion.SuccessHelper<V>.() -> Unit, failed: SimpleCompletionHandler.Companion.FailureHelper<V>.() -> Unit) : CompletionHandler<V, Unit>

A convenient CompletionHandler implementation that takes two lambdas at construction, avoiding the hideous inner class notation.

TextInputChannel

interface TextInputChannel : AsynchronousChannel

TextInputChannel provides a wrapper for a synchronous input reader that is as asynchronous as possible.

TextInterface

class TextInterface( val inputChannel: TextInputChannel, val outputChannel: TextOutputChannel, val errorChannel: TextOutputChannel)

A TextInterface represents an interface between an external process, device, or user and an Avail agent (e.g., an AvailBuilder or fiber). As such, it combines input, output, and error channels, corresponding to the usual notions of standard input, output, and error, respectively. These channels are each text-oriented, and constrained to operate on UTF-8 encoded character data.

TextOutputChannel

interface TextOutputChannel : AsynchronousChannel

TextOutputChannel provides a wrapper for a standard output stream, e.g., System.out and System.err, that is as asynchronous as possible.
