Public Functions Documentation🔗

function RequestHeader🔗

explicit RequestHeader(
    const cxx::UniqueId & uniqueClientQueueId,
    const uint32_t lastKnownClientQueueIndex
)

Constructs and initializes a RpcBaseHeader.

Parameters:

uniqueClientQueueId is the cxx::UniqueId of the client queue to which the response shall be delivered
lastKnownClientQueueIndex is the last know index of the client queue in the ChunkDistributor for fast lookup

function RequestHeader🔗

RequestHeader(
    const RequestHeader & other
)

function operator=🔗

RequestHeader & operator=(
    const RequestHeader & 
)

function RequestHeader🔗

RequestHeader(
    RequestHeader && rhs
) =default

function operator=🔗

RequestHeader & operator=(
    RequestHeader && rhs
) =default

function ~RequestHeader🔗

~RequestHeader() =default

function setSequenceId🔗

void setSequenceId(
    const int64_t sequenceId
)

Sets the sequence ID which is used to match a response to a request.

Parameters:

sequenceId is a consecutive number set by the user

Note: The user has to set this manually if multiple requests are sent before a response is read since a server might drop a requests or process the requests out of order and therefore the responses might also be out of order

function fromPayload🔗

static RequestHeader * fromPayload(
    void *const payload
)

function fromPayload🔗

static const RequestHeader * fromPayload(
    const void *const payload
)
