C# Class Osc, wekinator_examples

The Osc class provides the methods required to send, receive, and manipulate OSC messages. Several of the helper methods are static since a running Osc instance is not required for their use. When instanciated, the Osc class opens the PacketIO instance that's handed to it and begins to run a reader thread. The instance is then ready to service Send OscMessage requests and to start supplying OscMessages as received back. The Osc class can be called to Send either individual messages or collections of messages in an Osc Bundle. Receiving is done by delegate. There are two ways: either submit a method to receive all incoming messages or submit a method to handle only one particular address. Messages can be encoded and decoded from Strings via the static methods on this class, or can be hand assembled / disassembled since they're just a string (the address) and a list of other parameters in Object form.

Public Methods

Method	Description
Cancel ( ) : void
OscMessageToPacket ( OscMessage, oscM, byte packet, int length ) : int	Creates a packet (an array of bytes) from a single OscMessage. A convenience method, not requiring a start index.
OscMessageToString ( OscMessage, message ) : string	General static helper that returns a string suitable for printing representing the supplied OscMessage.
OscMessagesToPacket ( ArrayList messages, byte packet, int length ) : int	Puts an array of OscMessages into a packet (byte[]).
PacketToOscMessages ( byte packet, int length ) : ArrayList	Takes a packet (byte[]) and turns it into a list of OscMessages.
Send ( ArrayList oms ) : void	Sends a list of OSC Messages. Internally takes the OscMessage objects and serializes them into a byte[] suitable for sending to the PacketExchange.
Send ( OscMessage, oscMessage ) : void	Send an individual OSC message. Internally takes the OscMessage object and serializes it into a byte[] suitable for sending to the PacketIO.
SetAddressHandler ( string key, OscMessageHandler ah ) : void	Set the method to call back on when a message with the specified address is received. The method needs to have the OscMessageHandler signature - i.e. void amh( OscMessage oscM )
SetAllMessageHandler ( OscMessageHandler amh ) : void	Set the method to call back on when any message is received. The method needs to have the OscMessageHandler signature - i.e. void amh( OscMessage oscM )
StringToOscMessage ( string message ) : OscMessage,	Creates an OscMessage from a string - extracts the address and determines each of the values.
init ( UDPPacketIO, oscPacketIO ) : void

Private Methods

Method	Description
Dump ( byte packet, int start, int length ) : string
ExtractMessage ( ArrayList messages, byte packet, int start, int length ) : int	Extracts a messages from a packet.
ExtractMessages ( ArrayList messages, byte packet, int start, int length ) : int	Receive a raw packet of bytes and extract OscMessages from it. Used internally. The packet may contain a OSC message or a bundle of messages.
ExtractString ( byte packet, int start, int length ) : string	Removes a string from a packet. Used internally.
InsertString ( string s, byte packet, int start, int length ) : int	Inserts a string, correctly padded into a packet. Used internally.
OscMessageToPacket ( OscMessage, oscM, byte packet, int start, int length ) : int	Creates an array of bytes from a single OscMessage. Used internally. Can specify where in the array of bytes the OscMessage should be put.
PadSize ( int rawSize ) : int	Takes a length and returns what it would be if padded to the nearest 4 bytes.
Read ( ) : void	Read Thread. Loops waiting for packets. When a packet is received, it is dispatched to any waiting All Message Handler. Also, the address is looked up and any matching handler is called.
Start ( ) : void

Method Details

Cancel() public method

public Cancel ( ) : void
return	void

OscMessageToPacket() public static method

Creates a packet (an array of bytes) from a single OscMessage.

A convenience method, not requiring a start index.

public static OscMessageToPacket ( OscMessage, oscM, byte packet, int length ) : int
oscM	OscMessage,	The OscMessage to be returned as a packet.
packet	byte	The packet to be populated with the OscMessage.
length	int	The usable size of the array of bytes.
return	int

OscMessageToString() public static method

General static helper that returns a string suitable for printing representing the supplied OscMessage.

public static OscMessageToString ( OscMessage, message ) : string
message	OscMessage,	The OscMessage to be stringified.
return	string

OscMessagesToPacket() public static method

Puts an array of OscMessages into a packet (byte[]).

public static OscMessagesToPacket ( ArrayList messages, byte packet, int length ) : int
messages	ArrayList	An ArrayList of OscMessages.
packet	byte	An array of bytes to be populated with the OscMessages.
length	int	The size of the array of bytes.
return	int

PacketToOscMessages() public static method

Takes a packet (byte[]) and turns it into a list of OscMessages.

public static PacketToOscMessages ( byte packet, int length ) : ArrayList
packet	byte	The packet to be parsed.
length	int	The length of the packet.
return	ArrayList

Send() public method
