17.1.5.2. TopicDataType¶
-
class eprosima::fastdds::dds::TopicDataType¶
Class TopicDataType used to provide the DomainRTPSParticipant with the methods to serialize, deserialize and get the key of a specific data type. The user should created a class that inherits from this one, where Serialize and deserialize methods MUST be implemented. ,
Subclassed by eprosima::fastdds::dds::builtin::TypeLookup_ReplyPubSubType, eprosima::fastdds::dds::builtin::TypeLookup_RequestPubSubType
Public Functions
-
inline TopicDataType()¶
Constructor.
-
inline virtual ~TopicDataType()¶
Destructor.
-
virtual bool serialize(void *data, fastrtps::rtps::SerializedPayload_t *payload) = 0¶
Serialize method, it should be implemented by the user, since it is abstract. It is VERY IMPORTANT that the user sets the SerializedPayload length correctly.
- Parameters
data – [in] Pointer to the data
payload – [out] Pointer to the payload
- Returns
True if correct.
-
virtual bool deserialize(fastrtps::rtps::SerializedPayload_t *payload, void *data) = 0¶
Deserialize method, it should be implemented by the user, since it is abstract.
- Parameters
payload – [in] Pointer to the payload
data – [out] Pointer to the data
- Returns
True if correct.
-
virtual std::function<uint32_t()> getSerializedSizeProvider(void *data) = 0¶
Gets the SerializedSizeProvider function.
- Parameters
data – Pointer
- Returns
function
-
virtual void *createData() = 0¶
Create a Data Type.
- Returns
Void pointer to the created object.
-
virtual void deleteData(void *data) = 0¶
Remove a previously created object.
- Parameters
data – Pointer to the created Data.
-
virtual bool getKey(void *data, fastrtps::rtps::InstanceHandle_t *ihandle, bool force_md5 = false) = 0¶
Get the key associated with the data.
- Parameters
data – [in] Pointer to the data.
ihandle – [out] Pointer to the Handle.
force_md5 – [in] Force MD5 checking.
- Returns
True if correct.
-
inline void setName(const char *nam)¶
Set topic data type name
- Parameters
nam – Topic data type name
-
inline bool auto_fill_type_object() const¶
