Detailed Description

Header included in each discovery message containing the version of the discovery protocol, the process UUID of the sender node, the type of message (ADV, SUB, ... ) and optional flags.

Deprecated:

This class is deprecated. Discovery uses the ignition::msgs::Discovery message.

SetPUuid.

SetFlags()

void SetFlags

(

const uint16_t

_flags

)

Set the message flags.

Parameters

[in]

_flags

Used for enable optional features.

_buffer

)

Unserialize the header.

Parameters
