Detailed Description

This module describes the C Adapter API.

Adapters are pluggable components that allow RTI Routing Service to consume and produce data for different data domains (e.g., Connext DDS, MQTT, Socket, etc.).

By default, Routing Service is distributed with a builtin DDS adapter. Any other adapter plugins must be provided as external components registered through the XML configuration or through the service API.

The following figure shows an overview of the Routing Service adapter.

RouterAdapterOverview.svg

Input adapters are used to collect data samples from different data domains, such as DDS or MQTT. The input samples are processed by the Routing Service engine and are passed along to output adapters through the Processor, applying any Transformation beforehand if present.

For additional details about Adapter configuration see the RTI Routing Service User's Manual.

Stream Discovery

A Route cannot forward data until the type representations (e.g., TypeCode) associated with the input and output streams are available.

If a Route refers to types that are not defined in the configuration file, RTI Routing Service has to discover their type representation (e.g., TypeCode) before creating the RTI_RoutingServiceStreamReader and RTI_RoutingServiceStreamWriter. The adapter discovery API is used to provide stream and type information in a data domain to Routing Service*.

The discovery API consists of the following methods:

These methods provide access to RTI_RoutingServiceStreamReader used to discover streams in the data domain associated with a connection.

The input stream discovery RTI_RoutingServiceStreamReader provides information about input streams. An input stream is a stream from which an input's RTI_RoutingServiceStreamReader reads data. Notification of disposed scenarios, where an input stream disappears, are also made using the input stream discovery StreamReader.

In the builtin DDS adapter, the input stream discovery StreamReader is associated with the publication builtin DataReader of the DomainParticipant.

The output stream discovery RTI_RoutingServiceStreamReader provides information about output streams. An output stream is a stream to which an output's RTI_RoutingServiceStreamWriter can write data. Notification of disposed scenarios, where an output stream disappears, are also made using the output stream discovery StreamReader.

In the builtin DDS adapter, the output stream discovery StreamReader is associated with the subscription builtin DataReader of the DomainParticipant.

The samples provided by the stream discovery StreamReaders have the type RTI_RoutingServiceStreamInfo.

Typedef Documentation

◆ RTI_RoutingServiceStreamWriter

StreamWriter.

A StreamWriter provides a way to write samples of a specific type in a data domain.

In the XML configuration file, StreamWriters are associated with the tag <output> within <route> and <auto_route>.

The StreamWriter type is a typedef to a 'void *' pointer. The concrete implementation is up to the adapter implementor.

◆ RTI_RoutingServiceStreamWriter_WriteFcn

typedef int(* RTI_RoutingServiceStreamWriter_WriteFcn) (RTI_RoutingServiceStreamWriter stream_writer, const RTI_RoutingServiceSample *sample_list, const RTI_RoutingServiceSampleInfo *info_list, int count, RTI_RoutingServiceEnvironment *env)

Prototype of the function that writes a collection of data samples to an output stream.

Required: Only when the adapter is used to write data.

Parameters
stream_writer<<in>> Stream writer.
sample_list<<in>> Array of samples. The data representation associated with the samples will be given by the value of the connection attribute com.rti.routingservice.adapter.data_representation_kind that is obtained using the associated RTI_RoutingServiceStreamInfo.
info_list<<in>> Array of sample infos. The info representation associated with the sample infos will be given by the value of the connection attribute com.rti.routingservice.adapter.info_representation_kind that is obtained using the associated RTI_RoutingServiceStreamInfo.
count<<in>> Number of samples in the sample list
env<<inout>> Environment for error indications.
Returns
Number of samples written.

◆ RTI_RoutingServiceStreamReader

StreamReader.

A StreamReader provides a way to read samples of a specific type from a data domain.

In the XML configuration file, StreamReaders are associated with the tag <input> within <route> and <auto_route>.

The StreamReader type is a typedef to a 'void *' pointer. The concrete implementation is up to the adapter implementor.

◆ RTI_RoutingServiceStreamReaderListener_OnDataAvailableCallback

typedef void(* RTI_RoutingServiceStreamReaderListener_OnDataAvailableCallback) (RTI_RoutingServiceStreamReader stream_reader, void *listener_data)

Prototype of the callback used to notify of new samples.

When a StreamReader receives new data, it will use this callback to notify RTI Routing Service that there are new samples.

Required: Only when the adapter is used to read data.

Parameters
stream_reader<<in>> Stream reader.
listener_data<<inout>> Data associated with the listener when the listener is set.

◆ RTI_RoutingServiceStreamReader_ReadFcn

typedef void(* RTI_RoutingServiceStreamReader_ReadFcn) (RTI_RoutingServiceStreamReader stream_reader, RTI_RoutingServiceSample **sample_list, RTI_RoutingServiceSampleInfo **info_list, int *count, RTI_RoutingServiceEnvironment *env)

Prototype of the function that reads a collection of data samples and sample infos from an input stream.

When RTI Routing Service is done using the samples, it will 'return the loan' to the StreamReader by calling RTI_RoutingServiceStreamReader_ReturnLoanFcn.

Required: Only when the adapter is used to read data.

Parameters
stream_reader<<in>> Stream reader.
sample_list<<out>> Array that will hold the output samples. This array will be provided by the StreamReader. The contents of the array are typically structures of the type DDS_DynamicData (see the RTI Connext documentation). But in general, the data representation associated with the output samples will be given by the value of the connection attribute com.rti.routingservice.adapter.data_representation_kind that is obtained using the associated RTI_RoutingServiceStreamInfo.
info_list<<out>> Array that will hold the output sample infos. This array will be provided by the StreamReader. It can be NULL if there is no info associated to the samples. The contents of the array are typically structures of the type DDS_SampleInfo (see the RTI Connext documentation). But in general the info representation associated with the output sample infos will be given by the value of the connection attribute com.rti.routingservice.adapter.info_representation_kind that is obtained using the associated RTI_RoutingServiceStreamInfo.
count<<out>> Number of output samples. The value must be greater than or equal to zero.
env<<inout>> Environment for error indications.

In the XML configuration file, Sessions are associated with the tag <session> within a domain route. For each <session> tag, RTI Routing Service will create two adapter Sessions, one per connection.

The Session type is a typedef to a 'void *' pointer. The concrete implementation is up to the adapter implementor.
