class ExchangeContext

Defined at line 120 of file gen/third_party/openweave-core/src/include/Weave/Core/WeaveExchangeMgr.h

This class represents an ongoing conversation (ExchangeContext) between two or more nodes.

It defines methods for encoding and communicating Weave messages within an ExchangeContext

over various transport mechanisms, for example, TCP, UDP, or Weave Reliable Messaging.

void AddRef ()

in order to use reference counting (see refCount below)

we use a hold/free paradigm where users of the exchange

can hold onto it while it's out of their direct control

to make sure it isn't closed before everyone's ready.

Name	Value	Comments
kSendFlag_AutoRetrans	0x0001	Used to indicate that automatic retransmission is enabled.
kSendFlag_ExpectResponse	0x0002	Used to indicate that a response is expected within a specified timeout.
kSendFlag_RetransmissionTrickle	0x0004	Used to indicate the requirement of retransmissions for Trickle.
kSendFlag_DelaySend	0x0008	Used to indicate that the sending of the current message needs to be delayed.
kSendFlag_ReuseMessageId	0x0010	Used to indicate that the message ID in the message header can be reused.
kSendFlag_ReuseSourceId	0x0020	Used to indicate that the source node ID in the message header can be reused.
kSendFlag_RetainBuffer	0x0040	Used to indicate that the message buffer should not be freed after sending.
kSendFlag_AlreadyEncoded	0x0080	Used to indicate that the message is already encoded.
kSendFlag_DefaultMulticastSourceAddress	0x0100	Used to indicate that default IPv6 source address selection should be used when sending IPv6 multicast messages.
