Returns:

  • (Boolean)

Returns:

  • (Boolean)

def can_handle_request_retries?(version); version && version >= 9 end

#can_put_version_in_packet?(version) ⇒ Boolean

Test whether given version of agent has the protocol version embedded in each packet (this is generally inferred by the version in the received packet not being Packet::DEFAULT_VERSION, which is true of all with version >= 12)

Returns:

  • (Boolean)

Returns:

  • (Boolean)

# File 'lib/right_agent/protocol_version_mixin.rb', line 51

def can_route_to_response_queue?(version); version && version >= 10 end

rather than the deprecated TagQuery packet

Returns:

  • (Boolean)

# File 'lib/right_agent/protocol_version_mixin.rb', line 39

def can_use_router_query_tags?(version); version && version >= 8 end
