This means that if you have multiple subscriptions which overlap (that is a particular Message is relevant to all of them) you will be presented with the same message multiple times when you use the MessageIterator, each time with a different CorrelationId. If you specify true for this then a Message may be presented with multiple CorrelationId's.
| void setApplicationIdentityKey | ( | const std::string & | applicationIdentityKey | ) |
Set the application identity key (AIK) which uniquely identifies this application for this session.
| void setAuthenticationOptions | ( | const char * | authOptions | ) |
Set the specified authOptions as authentication option.
| void setAutoRestartOnDisconnection | ( | bool | autoRestart | ) |
Set whether to automatically retry connecting if the connection to a server gets disconnected. The default is true. The number of times such a retry is attempted is controlled by numStartAttempts.
| void setBandwidthSaveModeDisabled | ( | bool | isDisabled | ) |
If the specified isDisabled is true, then disable bandwidth saving measures. The default value is false.
| void setClientMode | ( | int | clientMode | ) |
Set how to connect to the API. The default is AUTO which will try to connect to the desktop API but fall back to the server API if the desktop is not available.

| void setDefaultKeepAliveInactivityTime | ( | int | inactivityMsecs | ) |
Set to the specified inactivityMsecs the amount of time that no traffic can be received on a connection before the ping-based keep-alive mechanism is triggered; if no traffic is received for this duration then a keep-alive ping is sent to the remote end to solicit a response. If inactivityMsecs == 0, then no keep-alive pings will be sent. The behavior of this function is undefined unless inactivityMsecs is a non-negative value. The default value is 20,000 milliseconds. Note that not all back-end connections provide ping-based keep-alives; this option is ignored by such connections.
| void setDefaultKeepAliveResponseTimeout | ( | int | timeoutMsecs | ) |
When a keep-alive ping is sent, wait for the specified timeoutMsecs to receive traffic (of any kind) before terminating the connection due to inactivity. If timeoutMsecs == 0, then connections are never terminated due to the absence of traffic after a keep-alive ping. The behavior of this function is undefined unless timeoutMsecs is a non-negative value. The default value is 5,000 milliseconds. Note that not all back-end connections provide support for ping-based keep-alives; this option is ignored by such connections.
| void setDefaultServices | ( | const char * | defaultServices | ) |
DEPRECATED
Set the default service for the session. This function is deprecated; see setDefaultSubscriptionService.
| void setDefaultSubscriptionService | ( | const char * | serviceIdentifier | ) |

The behavior is undefined unless serviceIdentifier matches the regular expression ^//[-_.a-zA-Z0-9]+/[-_.a-zA-Z0-9]+$. The default is "//blp/mktdata". For more information on when this will be used see QUALIFYING SUBSCRIPTION STRINGS section in blpapi_subscriptionlist.
| void setDefaultTopicPrefix | ( | const char * | prefix | ) |
Set the default topic prefix to be used when a subscription does not specify a prefix to the specified prefix. The default is "/ticker/". For more information on when this will be used see QUALIFYING SUBSCRIPTION STRINGS section in blpapi_subscriptionlist.
| void setFlushPublishedEventsTimeout | ( | int | timeoutMsecs | ) |
Set the timeout, in milliseconds, for ProviderSession to flush published events before stopping. The behavior is not defined unless the specified timeoutMsecs is a positive value. The default value is 2000.
| void setKeepAliveEnabled | ( | bool | isEnabled | ) |
If the specified isEnabled is false, then disable all keep-alive mechanisms, both from the client to the server and from the server to the client; otherwise enable keep-alive pings both from the client to the server (as configured by setDefaultKeepAliveInactivityTime and setDefaultKeepAliveResponseTimeout if the connection supports ping-based keep-alives), and from the server to the client as specified by the server configuration.
| void setMaxEventQueueSize | ( | size_t | eventQueueSize | ) |
Set the maximum number of outstanding undelivered events per session to the specified eventQueueSize. All subsequent events delivered over the network will be dropped by the session if the number of outstanding undelivered events is eventQueueSize, the specified threshold. The default value is 10000.
| void setMaxPendingRequests | ( | int | maxPendingRequests | ) |
Set the maximum number of requests which can be pending to the specified maxPendingRequests. The default is 1024.

| int setServerAddress | ( | const char * | serverHost, |
| unsigned short | serverPort, | ||
| size_t | index | ||
| ) |
Set the server address at the specified index in the server list using the specified serverHost and serverPort. The default is "127.0.0.1:8194". Behavior is undefined if the specified serverHost is a nullptr or points to an empty string.

Behavior is undefined if the specified serverHost is a nullptr or points to an empty string.
| void setServerHost | ( | const char * | host | ) |
Set the API server host to connect to when using the server API to the specified host, which is a hostname or an IPv4 address (that is, a.b.c.d).

| const CorrelationId & | correlationId = CorrelationId() |
||
| ) |
Set the specified authOptions as the AuthOptions for the session identity, enabling automatic authorization of the session identity during startup. The optionally specified correlationId is used to identify the messages associated with the session identity.
Return the actual CorrelationId that identifies the messages associated with the session identity.
The session identity lifetime is tied to the session's lifetime, so it is guaranteed that the session identity will remain authorized during the entire duration of the session. The identity will be authorized before the session starts. The session will terminate if the identity fails to authorize or is revoked.
The session identity is used to send requests and make subscriptions if no other identity is provided.
By default the session identity is not authorized.
| void setSessionName | ( | const std::string & | sessionName | ) |
Set the session name which can be used to identify the log lines pertaining to the session. The length of the session name should be short, and never exceed 100 characters. be short, and never exceed 100 characters. Session names cannot have embedded NUL (\0) characters.
| void setSlowConsumerWarningHiWaterMark | ( | float | hiWaterMark | ) |
Set the point at which "slow consumer" events will be generated, using the specified highWaterMark as a fraction of maxEventQueueSize; the default value is 0.75. A warning event will be generated when the number of outstanding undelivered events passes above hiWaterMark * maxEventQueueSize. The behavior of the function is undefined unless 0.0 < hiWaterMark <= 1.0. Further, at the time that Session.start() is called, it must be the case that slowConsumerWarningLoWaterMark() * maxEventQueueSize() < slowConsumerWarningHiWaterMark() * maxEventQueueSize().
| void setSlowConsumerWarningLoWaterMark | ( | float | loWaterMark | ) |

A warning cleared event will be generated when the number of outstanding undelivered events drops below loWaterMark * maxEventQueueSize. The behavior of the function is undefined unless 0.0 <= loWaterMark < 1.0. Further, at the time that Session.start() is called, it must be the case that slowConsumerWarningLoWaterMark() * maxEventQueueSize() < slowConsumerWarningHiWaterMark() * maxEventQueueSize().
| void setTlsOptions | ( | const TlsOptions & | tlsOptions | ) |
Set the TLS options to the specified tlsOptions.
| float slowConsumerWarningHiWaterMark | ( | ) | const |
Return the fraction of maxEventQueueSize at which "slow consumer" event will be generated.
