Constructor & Destructor Documentation

template<typename T>

connext::Sample< T >::Sample ( )

inline

Creates a sample with default data and info values.

The data is deeply initialized using the corresponding TypeSupport

See Also: FooTypeSupport::initialize_data

template<typename T>

connext::Sample< T >::Sample ( const Sample< T > & other )

inline

Creates a sample making a deep copy of another sample.

template<typename T >

Sample< T >::Sample ( SampleRef< T > sample_ref )

Creates a sample as a deep copy of the contents referenced by a WriteSampleRef.

Member Function Documentation

template<typename T>

SampleIdentity_t connext::Sample< T >::identity ( ) const

inline

Gets the identity of this sample.

The identity is assigned by the middleware upon reception.

template<typename T>

SampleIdentity_t connext::Sample< T >::related_identity ( ) const

inline

Gets the identity of a sample that is related to this one.

When a connext::Requester receives a reply, the reply Sample contains the identity of the related request.

Returns: The identity of another sample that is related to this one, or DDS_UNKNOWN_SAMPLE_IDENTITY if there is not a related sample.
