Value-semantic type for options related to a queue.
See Component bmqt_queueoptions
typedef bsl::pair<SubscriptionHandle, Subscription> bmqt::QueueOptions::HandleAndSubscription |
typedef bsl::vector<HandleAndSubscription> bmqt::QueueOptions::SubscriptionsSnapshot |
bmqt::QueueOptions::QueueOptions | ( | bslma::Allocator * | allocator = 0 |
) | [explicit] |
Create a new QueueOptions using the optionally specified allocator
.
bmqt::QueueOptions::QueueOptions | ( | const QueueOptions & | other, | |
bslma::Allocator * | allocator = 0 | |||
) |
Create a new QueueOptions by copying values from the specified other
, using the optionally specified allocator
.
QueueOptions& bmqt::QueueOptions::setMaxUnconfirmedMessages | ( | int | value | ) |
Set the maxUnconfirmedMessages to the specified value
. The behavior is undefined unless value >= 0
. If the specified value
is set to 0, it means that the consumer does not receive any messages. This might be useful when the consumer is shutting down and wants to process only pending messages, or when it is unable to process new messages because of transient issues.
QueueOptions& bmqt::QueueOptions::setMaxUnconfirmedBytes | ( | int | value | ) |
Set the maxUnconfirmedBytes to the specified value
. The behavior is undefined unless value >= 0
.
QueueOptions& bmqt::QueueOptions::setConsumerPriority | ( | int | value | ) |
Set the consumerPriority to the specified value
. The behavior is undefined unless 'k_CONSUMER_PRIORITY_MIN <= value <= k_CONSUMER_PRIORITY_MAX'
QueueOptions& bmqt::QueueOptions::setSuspendsOnBadHostHealth | ( | bool | value | ) |
Set whether the queue suspends operation while host is unhealthy.
QueueOptions& bmqt::QueueOptions::merge | ( | const QueueOptions & | other | ) |
"Merges" another QueueOptions
into this one, by invoking setF(other.F()) for all fields F
for which other.hasF()
is true. Returns the instance on which the method was invoked.
bool bmqt::QueueOptions::addOrUpdateSubscription | ( | bsl::string * | errorDescription, | |
const SubscriptionHandle & | handle, | |||
const Subscription & | subscription | |||
) |
Add, or update if it exists, the specified subscription
for the specified handle
. Return true on success, otherwise return false and load the specified errorDescription
with a description of the error. Note that errorDescription
may be null if the caller does not care about getting error messages, but users are strongly encouraged to log error string if this API returns failure.
EXPERIMENTAL. Do not use until this feature is announced.
bool bmqt::QueueOptions::removeSubscription | ( | const SubscriptionHandle & | handle | ) |
Return false if subscription does not exist.
EXPERIMENTAL. Do not use until this feature is announced.
void bmqt::QueueOptions::removeAllSubscriptions | ( | ) |
Remove all subscriptions.
EXPERIMENTAL. Do not use until this feature is announced.
int bmqt::QueueOptions::maxUnconfirmedMessages | ( | ) | const |
Get the number for the maxUnconfirmedMessages parameter.
int bmqt::QueueOptions::maxUnconfirmedBytes | ( | ) | const |
Get the number for the maxUnconfirmedBytes parameter.
int bmqt::QueueOptions::consumerPriority | ( | ) | const |
Get the number for the consumerPriority parameter.
bool bmqt::QueueOptions::suspendsOnBadHostHealth | ( | ) | const |
Get whether the queue suspends operation while host is unhealthy.
bool bmqt::QueueOptions::hasMaxUnconfirmedMessages | ( | ) | const |
Returns whether maxUnconfirmedMessages
has been set for this object, or whether it implicitly holds k_DEFAULT_MAX_UNCONFIRMED_MESSAGES
.
bool bmqt::QueueOptions::hasMaxUnconfirmedBytes | ( | ) | const |
Returns whether maxUnconfirmedBytes
has been set for this object, or whether it implicitly holds k_DEFAULT_MAX_UNCONFIRMED_BYTES
.
bool bmqt::QueueOptions::hasConsumerPriority | ( | ) | const |
Returns whether consumerPriority
has been set for this object, or whether it implicitly holds k_DEFAULT_CONSUMER_PRIORITY
.
bool bmqt::QueueOptions::hasSuspendsOnBadHostHealth | ( | ) | const |
Returns whether suspendsOnBadHostHealth
has been set for this object, or whether it implicitly holds k_DEFAULT_SUSPENDS_ON_BAD_HOST_HEALTH
.
bool bmqt::QueueOptions::loadSubscription | ( | Subscription * | subscription, | |
const SubscriptionHandle & | handle | |||
) | const |
Return false if subscription does not exist.
EXPERIMENTAL. Do not use until this feature is announced.
void bmqt::QueueOptions::loadSubscriptions | ( | SubscriptionsSnapshot * | snapshot | ) | const |
Load all handles and subscriptions into the specified snapshot
.
EXPERIMENTAL. Do not use until this feature is announced.
bsl::ostream& bmqt::QueueOptions::print | ( | bsl::ostream & | stream, | |
int | level = 0 , |
|||
int | spacesPerLevel = 4 | |||
) | const |
Format this object to the specified output stream
at the (absolute value of) the optionally specified indentation level
and return a reference to stream
. If level
is specified, optionally specify spacesPerLevel
, the number of spaces per indentation level for this and all of its nested objects. If level
is negative, suppress indentation of the first line. If spacesPerLevel
is negative format the entire output on one line, suppressing all but the initial indentation (as governed by level
). If stream
is not valid on entry, this operation has no effect.
