Documentation

class Transport t where Source #

Abstract over the underlying transport protocol.

Methods

sendPacket :: t -> Packet -> IO () Source #

Encode and send an OSC packet.

recvPacket :: t -> IO Packet Source #

Receive and decode an OSC packet.

close :: t -> IO () Source #

Close an existing connection.

Instances

Transport UDP Source #	`UDP` is an instance of `Transport`.
Instance details Defined in Sound.OSC.Transport.FD.UDP Methods sendPacket :: UDP -> Packet -> IO () Source # recvPacket :: UDP -> IO Packet Source # close :: UDP -> IO () Source #
Transport TCP Source #	`TCP` is an instance of `Transport`.
Instance details Defined in Sound.OSC.Transport.FD.TCP Methods sendPacket :: TCP -> Packet -> IO () Source # recvPacket :: TCP -> IO Packet Source # close :: TCP -> IO () Source #

withTransport :: Transport t => IO t -> (t -> IO a) -> IO a Source #

Bracket OSC communication.

Send

sendMessage :: Transport t => t -> Message -> IO () Source #

sendPacket of Packet_Message.

sendBundle :: Transport t => t -> Bundle -> IO () Source #

sendPacket of Packet_Bundle.

Receive

recvBundle :: Transport t => t -> IO Bundle Source #

Variant of recvPacket that runs packet_to_bundle.

recvMessage :: Transport t => t -> IO (Maybe Message) Source #

Variant of recvPacket that runs packet_to_message.

recvMessages :: Transport t => t -> IO [Message] Source #

Variant of recvPacket that runs packetMessages.

Timeout

recvPacketTimeout :: Transport t => Double -> t -> IO (Maybe Packet) Source #

Variant of recvPacket that implements an n second timeout.

Wait

waitUntil :: Transport t => t -> (Packet -> Bool) -> IO Packet Source #

Wait for a Packet where the supplied predicate is True, discarding intervening packets.

waitFor :: Transport t => t -> (Packet -> Maybe a) -> IO a Source #

Wait for a Packet where the supplied function does not give Nothing, discarding intervening packets.

waitImmediate :: Transport t => t -> IO Packet Source #

waitUntil packet_is_immediate.

waitMessage :: Transport t => t -> IO Message Source #

waitFor packet_to_message, ie. an incoming Message or immediate mode Bundle with one element.

waitAddress :: Transport t => t -> Address_Pattern -> IO Packet Source #

A waitFor for variant using packet_has_address to match on the Address_Pattern of incoming Packets.

waitReply :: Transport t => t -> Address_Pattern -> IO Message Source #

Variant on waitAddress that returns matching Message.

waitDatum :: Transport t => t -> Address_Pattern -> IO [Datum] Source #

Variant of waitReply that runs messageDatum.
