Detailed Description

Contains the parameters for creating a FooBarRequester.

The following parameters are required to create a Requester:

A DDS_DomainParticipant (RTI_Connext_RequesterParams::participant), and
Either a service name (RTI_Connext_RequesterParams::service_name)
Or custom topic names (RTI_Connext_RequesterParams::request_topic_name and RTI_Connext_RequesterParams::reply_topic_name)

The rest of the parameters that can be set in a RequesterParams object are optional.

Field Documentation

DDS_DomainParticipant* RTI_Connext_RequesterParams::participant

The participant this requester uses to join a DDS domain.

char* RTI_Connext_RequesterParams::service_name

The service name that Repliers and Requester use to match and communicate.

A Requester and a Replier need to be configured with the same topic names in order to match.

The service name is used to generate a request topic and a reply topic that the Requester and Replier will use to communicate. For example, the service name "MyService" will be used to create topics named "MyServiceRequest" and "MyServiceReply".

In some cases, the name of these topics is known beforehand or needs to be customized for another reason. The service name can be overridden by setting specific request and reply topic names using RTI_Connext_RequesterParams::request_topic_name and RTI_Connext_RequesterParams::reply_topic_name.

char* RTI_Connext_RequesterParams::request_topic_name

Sets a specific request topic name.

The specified topic name will be used, instead of allowing a topic name to be generated based on the RTI_Connext_RequesterParams::service_name. If that topic already exists, it will be reused.

char* RTI_Connext_RequesterParams::reply_topic_name

Sets a specific reply topic name.

The specified topic name will be used, instead of allowing a topic name to be generated based on the RTI_Connext_RequesterParams::service_name. If that topic already exists, it will be reused.

char* RTI_Connext_RequesterParams::qos_library_name

Sets the library that contains the RTI_Connext_RequesterParams::qos_profile_name.

See Also: RTI_Connext_RequesterParams::qos_profile_name

char* RTI_Connext_RequesterParams::qos_profile_name

Sets a QoS profile for the entities in this requester.

Specifies an XML QoS profile that will be used to configure the quality of service of a Requester's underlying request DataWriter and reply DataReader.

Within that profile, the DataWriter QoS in <datawriter_qos> will be used to configure the request DataWriter and the DataReader.

Alternatively, you can set the QoS using the DataWriterQos and DataReaderQos objects (RTI_Connext_RequesterParams::datawriter_qos, RTI_Connext_RequesterParams::datareader_qos).

The library where this profile is located has to be set with RTI_Connext_RequesterParams::qos_library_name

See Also: RTI_Connext_RequesterParams::qos_library_name; Configuring Request-Reply QoS profiles; Configuring QoS Profiles with XML

struct DDS_DataWriterQos* RTI_Connext_RequesterParams::datawriter_qos

Sets the quality of service of the request DataWriter.

See Also: RTI_Connext_RequesterParams::qos_profile_name

struct DDS_DataReaderQos* RTI_Connext_RequesterParams::datareader_qos

Sets the quality of service of the request DataReader.

See Also: RTI_Connext_RequesterParams::qos_profile_name

DDS_Publisher* RTI_Connext_RequesterParams::publisher

Sets a specific Publisher.

By default, a Requester uses the DomainParticipant's implicit Publisher. Sometimes a different Publisher may be needed, for example, to use non-default PublisherQos.

DDS_Subscriber* RTI_Connext_RequesterParams::subscriber

Sets a specific Subscriber.

By default, a Requester uses the DomainParticipant's implicit Subscriber. Sometimes a different Subscriber may be needed, for example, to use non-default SubscriberQos.
