Detailed Description

template<typename TopicType>
struct rti::topic::topic_type_has_pointer_members< TopicType >

<<extension>> Indicates if a topic type contains directly or indirectly IDL pointer members.

This template is specialized in the generated code for topic types that do contain pointers.

This trait enables (when it's false_type) or disables (when it's true_type) the DataReader read/take operations that copy instead of loaning the data (for example, dds::sub::DataReader::take(SamplesFWIterator, int32_t))
