Contains the options which the user can specify when creating a session.
To use non-default options on a Session, create a SessionOptions instance and set the required options and then supply it when creating a Session.
blpapi::SessionOptions::SessionOptions | ( | ) |
Create a SessionOptions with all options set to the standard defaults.
blpapi::SessionOptions::SessionOptions | ( | const SessionOptions & | original | ) |
Copy constructor
blpapi::SessionOptions::~SessionOptions | ( | ) |
Destroy this SessionOptions.
SessionOptions& blpapi::SessionOptions::operator= | ( | const SessionOptions & | rhs | ) |
Assign to this object the value of the specified rhs
object.
void blpapi::SessionOptions::setServerHost | ( | const char * | host | ) |
Set the API server host to connect to when using the server API to the specified host
. A hostname or an IPv4 address (that is, a.b.c.d). The default is "127.0.0.1".
void blpapi::SessionOptions::setServerPort | ( | unsigned short | port | ) |
Set the port to connect to when using the server API to the specified port
. The default is 8194.
int blpapi::SessionOptions::setServerAddress | ( | const char * | serverHost, | |
unsigned short | serverPort, | |||
size_t | index | |||
) |
Set the server address at the specified index
using the specified serverHost
and serverPort
.
int blpapi::SessionOptions::removeServerAddress | ( | size_t | index | ) |
Remove the server address at the specified index
.
void blpapi::SessionOptions::setConnectTimeout | ( | unsigned int | timeoutMilliSeconds | ) |
Set the connection timeout in milliseconds when connecting to the API. The default is 5000 milliseconds. Behavior is not defined unless the specified timeoutMilliSeconds
is in range of [1 .. 120000] milliseconds
void blpapi::SessionOptions::setDefaultServices | ( | const char * | defaultServices | ) |
Set the default service for the session. This function is deprecated; see setDefaultSubscriptionService
.
void blpapi::SessionOptions::setDefaultSubscriptionService | ( | const char * | serviceIdentifier | ) |
Set the default service for subscriptions which do not specify a subscription server to the specified 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 blpapi::SessionOptions::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 blpapi::SessionOptions::setAllowMultipleCorrelatorsPerMsg | ( | bool | allowMultipleCorrelatorsPerMsg | ) |
Set whether the Session is allowed to associate more than one CorrelationId with a Message to the specified allowMultipleCorrelatorsPerMsg
. The default is false
. 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 blpapi::SessionOptions::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. DAPI always connects to the desktop API and will fail if it is not available. SAPI always connects to the server API and will fail if it is not available.
void blpapi::SessionOptions::setMaxPendingRequests | ( | int | maxPendingRequests | ) |
Set the maximum number of requests which can be pending to the specified maxPendingRequests
. The default is 1024.
void blpapi::SessionOptions::setAuthenticationOptions | ( | const char * | authOptions | ) |
Set the specified authOptions
as authentication option.
void blpapi::SessionOptions::setNumStartAttempts | ( | int | numStartAttempts | ) |
Set the maximum number of attempts to start a session by connecting a server.
void blpapi::SessionOptions::setAutoRestartOnDisconnection | ( | bool | autoRestart | ) |
Set whether automatically restarting connection if disconnected.
void blpapi::SessionOptions::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 blpapi::SessionOptions::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 blpapi::SessionOptions::setSlowConsumerWarningLoWaterMark | ( | float | loWaterMark | ) |
Set the point at which "slow consumer cleared" events will be generated, using the specified loWaterMark
as a fraction of maxEventQueueSize
; the default value is 0.5. 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 blpapi::SessionOptions::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 blpapi::SessionOptions::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 blpapi::SessionOptions::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 blpapi::SessionOptions::setRecordSubscriptionDataReceiveTimes | ( | bool | shouldRecord | ) |
Set whether the receipt time (accessed via blpapi::Message::timeReceived) should be recorded for subscription data messages. By default, the receipt time for these messages is not recorded.

Return the server port that this session connects to. If more than one server addresses are specified, return the port of the first server address.
size_t blpapi::SessionOptions::numServerAddresses | ( | ) | const |
Return the number of server addresses.
int blpapi::SessionOptions::getServerAddress | ( | const char ** | serverHost, | |
unsigned short * | serverPort, | |||
