Does RTI Connext support the IDL data-types "interface" and "valuetype"?

Note: Applies to RTI Connext 4.x and above RTI Connext does not support the IDL interface data type because it corresponds to remote procedure calls, a concept that does not apply to the data-centric, publish-subscribe (DCPS) communications model of the DDS standard. The valuetype data type is ...

Do I need to worry about Daylight Saving Time or time zones when using RTI Connext?

RTI Connext uses clocks to measure time and generate timestamps. The middleware uses two clocks: an internal clock and an external clock. The internal clock measures time and handles all timing in the middleware. The external clock is used solely to generate timestamps (such as the source timestamp ...

Are unbounded sequences really unbounded?

Note: Applies to RTI Connext 4.x through 5.1. ETA: As of 5.2, RTI Connext supports truly unbounded sequences and strings in the C, C++, and .NET APIs. Unbounded sequences are actually not unbounded at all. They are bounded sequences whose bound is initialized by RTI Connext instead of by the user. ...

Should I use static or dynamic libraries?

RTI Connext's static and dynamic libraries have the same tradeoffs as any other static and dynamic libraries. The main advantage of using dynamic libraries is less system-wide memory usage when there is more than one application using the same libraries on the machine. Starting a dynamically linked ...

What is the purpose of the narrow() method created for a type by rtiddsgen?

Note: Applies to RTI Connext 4.x and above The narrow method is a class-scope method that implements a safe down-cast for a pointer to an RTI Connext entity. It is a type-safe way to cast a pointer. The Java API does not require this method because Java casts are always type-safe. This method takes ...
