Dynamic Data: Access Union Discriminators

Connext uses the discriminator field of the struct to decide what field in the struct is actually sent on the wire. In this example we illustrate how to access the discriminator of a Union using the Dynamic Data API.

WaitSet with Status Condition

This is a simple example that shows how to receive notifications about data becoming available using a StatusCondition. This is the most efficient way to use WaitSets to be notified that you have new data.

Polling With Query Condition

In RTI Connext DDS, you have the option to query for data that is already in the DataReader's queue using a QueryCondition object. This lets you retrieve data from the queue based on the values of one or more fields inside of that data.

Creating a Custom Transport

This example illustrates how to use the RTI Pluggable Transport API. Our custom FILE transport uses regular files for communication, where each address/port maps to a file in the file-system.

Using QoS Profiles

In this example, we create a publisher and a subscriber application that communicate using QoS profiles. We illustrate how to load XML-specified QoS from different files and how to create DDS entities using the profiles specified in them.

Waitsets

This example shows how to use WaitSets to read data. We define a set of read and status conditions on which to wait, and attach them to the Waitset.

Using Sequences

In this example we illustrate how sequences can "own" the memory associated with it, or "borrow" that memory. We also show how to use the sequences created, changing the sequence's length every time we send a sample of each instance, assigning a random value to each sequence's elements.

Content Filtered Topic

A Content Filtered Topic is a Topic with filtering properties. In this example we illustrate how to enable a Content Filtered Topic using a parameterized expression. We also illustrate how to change the value of these parameters at runtime.

Using Type Codes

In this example we illustrate how to increase the resource limits for working with complex type codes. We also show how to manipulate metadata describing the message type.

Polling Read

In RTI Connext there are three ways to receive data. In this example we illustrate the method known as polling for data, where the application checks for new data calling DataReader's read() or take() method.
