Constructor & Destructor Documentation

ResponseHeader()

iox::popo::ResponseHeader::ResponseHeader ( const cxx::UniqueId & uniqueClientQueueId, const uint32_t lastKnownClientQueueIndex, const int64_t sequenceId )

explicitnoexcept

Constructs and initializes a RpcBaseHeader.

Parameters

[in]	uniqueClientQueueId	is the cxx::UniqueId of the client queue to which the response shall be delivered
[in]	lastKnownClientQueueIndex	is the last know index of the client queue in the ChunkDistributor for fast lookup
[in]	sequenceId	is a custom ID to map a response to a request

Member Function Documentation

hasServerError()

bool iox::popo::ResponseHeader::hasServerError ( ) const

noexcept

Obtains the server error flag.

Returns

true if there is an error, false otherwise
