Detailed Description

A message that holds an SdpMessage

Message format is:

Message header: 6 bytes 4 for cookie 1 for message type 1 for transaction id

Sdp header: 40 or 52 bytes 1 for is IPv6 4 or 16 for address 2 for port 16 for username guid 16 for password guid 1 for number of candidates

Candidates: 24 or 36 or 42 bytes per candidate 16 for foundation 1 for local preference 1 for candidateType, isIPv6, and isDualStack 4 or 16 for address 2 for port (4 or 16 for address) (2 for port)

Member Function Documentation

AsBytes()

byte [] NobleConnect.Sdp.Message.AsBytes

(

)

IsSDPMessage()

static bool NobleConnect.Sdp.Message.IsSDPMessage ( byte[]  buffer, int  index, int  count  )

static

Determine whether or not some bytes look like an sdp message

Size of message must be large enough for header and at least one candidate of maximum size (the dual stack relay). Cookie must match, message type and isIPv6 byte must be valid. Remaining message size must be sane given number of candidates. First candidate must look valid

Parameters

buffer
index
count

Returns

NextTransactionID()

static ReadOnlyByteArray NobleConnect.Sdp.Message.NextTransactionID ( )

static

Get a fresh transaction ID

Returns

Serialize()

void NobleConnect.Sdp.Message.Serialize

(

BufferView

buffer

)

Serialize the message to a buffer

Parameters

buffer

ToString()

override string NobleConnect.Sdp.Message.ToString

(

)

Get a human readable representation of the Message

This is not what is sent over the network. Just useful for debugging.

Returns
