Peer Class

A Peer describes the network connection originating a message in the callback functions found in oscinDAT, tcpipDAT, udpinDAT, udtinDAT.


Members

ownerOP (Read Only):

The OP to which this object belongs.

portint (Read Only):

The network port associated with the peer.

addressstr (Read Only):

The network address associated with the peer.

hostnamestr (Read Only):

The network hostname associated with the peer.

Methods

close()bool:

Close the peer connection. Returns True if successful. Closing a peer can be useful when implementing HTML server protocols for example.

sendBytes(message1, message2...)int:

Send a sequence of bytes through this connection. No terminators are appended. Note: the message will not be OSC formatted.

Messages can any combination of strings, byte arrays, or individual single-byte numeric values. To serialize non-byte values (example floats or integers) there are several python modules to do this, such as pickle or struct. Returns the number of bytes sent.

n.sendBytes( 'TYPE', 23, 255, 12, 0x34, b'\x01\x00\x02\x00\x03\x00\x00\x00')

sendOSC(address, valueList,... asBundle=False, useNonStandardTypes=True, use64BitPrecision=False)int:

Send an OSC formatted message through this connection. Multiple pairs of address/valueLists arguments to be passed. This method will automatically decide what OSC type to convert the passed values to.

Returns the number of bytes sent.

  • address - The OSC address to label this message with.
  • values - A list of values to send in this message.
  • asBundle - (Keyword, Optional) When true, all messages are sent inside a single bundle.
  • useNonStandardTypes - (Keyword, Optional) When True, values may be sent over using the non-standard OSC type. For example True and False will be sent as boolean T and F types, rather than an int with a value of 1 and 0. Available in 099.2018.21730 or later.
  • use64BitPrecision - (Keyword, Optional) When True, integer and float values will be sent over as 64-bit values. Requires useNonStandardTypes to also be True. Available in 099.2018.21730 or later.
vals = [1, b'abc', 'apple', [6,7,8], True, None, float("infinity")]
n.sendOSC('/abc', vals)
Integers
If useNonStandardTypes=True, then either a 32-bit or 64-bit integer, depending on the magnitude of the integer's current value.
If useNonStandardTypes=False, then a 32-bit integer if the magnitude fits in a 32-bit integer, or an exception if it's too large.
If use64BitPrecision=True, then always a 64-bit integer.
Floats
If use64BitPrecision=True, then always a 64-bit float.
If use64BitPrecision=False, then always a 32-bit float.
Float with value Infinity
If useNonStandardTypes=True, then the OSC Infinitum type.
If useNonStandardTypes=False, then always a 32-bit float.
Booleans
If useNonStandardTypes=True, then a boolean T or F type.
If useNonStandardTypes=False, then a 32-bit integer with a value of 1 or 0.
None
If useNonStandardTypes=True, then an OSC nil type.
If useNonStandardTypes=False, then a 32-bit integer with a value of 0.
Strings
A OSC string in all cases.
bytes or bytearray object
An OSC blob. Make sure to put the bytes/bytearray object into a list, and not just pass it directly to sendOSC. If passed directly to sendOSC not in a list then it will be treated as a list of individual integer values and not get sent as a blob.

send(message1, message2..., terminator='')int:

Send a sequence of strings through this connection. Note: the message will not be OSC formatted.

  • messsage - One or more strings to send across the network connection.
  • terminator - (Keyword, Optional) Specifies how the message is to be terminated. If no append terminator is specified, a null character will automatically be appended to the message. To send no terminator, use terminator=''.

Returns the number of bytes sent.

n.send('Hello', 'World',  terminator='\r\n') # send two strings with windows newline termination.
