Defines generic classes and macros to support user data types.
Defines the DDS user data type support.
DDS specifies strongly typed interfaces to read and write user data. For each data class defined by the application, there is a number of specialised classes that are required to facilitate the type-safe interaction of the application with RTI Connext DDS Micro.
RTI Connext DDS Micro provides an automatic means to generate all these type-specific classes with the RTI IDL Compiler User Manual utility. The complete set of automatic classes created for a hypothetical user data type named Foo
are shown below.
The macros defined here declare the strongly typed APIs needed to support an arbitrary user defined data of type Foo
.
#define DDS_DATAWRITER_CPP | ( | TDataWriter, | |
TData | |||
) |
Declares the interface required to support a user data type specific data writer.
Foo

Declares the interface required to support a user data type-specific data reader.

typedef DDS_HANDLE_TYPE_NATIVE DDS_InstanceHandle_t |
Type definition for an instance handle.
Handle to identiy different instances of the same DDSTopic of a certain type.
