API Naming Conventions

Structure & Class Names

RTI Connext DDS Micro makes a distinction between value types and interface types. Value types are types such as primitives, enumerations, strings, and structures whose identity and equality are determined solely by explicit state. Interface types are those abstract opaque data types that conceptually have an identity apart from their explicit state. Examples include all of the DDS_Entity subtypes. Instances of value types are frequently transitory and are declared on the stack. Instances of interface types typically have longer lifecycles, are accessible by pointer only, and may be managed by a factory object.

Value type structures are made more explicit through the use of C's structure tag syntax. For example, a DDS_Duration_t object must be declared as being of type "struct DDS_Duration_t," not simply "DDS_Duration_t." Interface types, by contrast, are always of typedef'ed types; their underlying representations are opaque.

API Documentation Terms

In the API documentation, the term module refers to a logical grouping of documentation and elements in the API.

At this time, typedefs that occur in the API, such as DDS_ReturnCode_t do not show up in the compound list or indices. This is a known limitation in the generated HTML.


Commonly used stereotypes in the API documentation include the following.
