Detailed Description

template<typename T>
class DDS::Sample< T >

Sample holds the data and related meta information.

Sample will allocate space for the sample data, and maintain that memory. The sample also includes SampleInfo which will be populated if the Sample instance is provided by a read() or similar operation of a DDS or RPC entity.
