18.2.3.7.2. GUID_t¶
-
struct GUID_t¶
Structure GUID_t, entity identifier, unique in DDS-RTPS Domain.
Public Functions
-
inline GUID_t() noexcept¶
Default constructor.
Contructs an unknown GUID.
-
inline GUID_t(const GuidPrefix_t &guid_prefix, uint32_t id) noexcept¶
Construct
- Parameters
guid_prefix – Guid prefix
id – Entity id
-
inline GUID_t(const GuidPrefix_t &guid_prefix, const EntityId_t &entity_id) noexcept¶
- Parameters
guid_prefix – Guid prefix
entity_id – Entity id
-
inline bool is_on_same_host_as(const GUID_t &other_guid) const¶
Checks whether this guid is from an entity on the same host as another guid.
Note
This method assumes the value of
other_guidwas originally assigned by Fast-DDS vendor.- Parameters
other_guid – GUID_t to compare to.
- Returns
true when this guid is on the same host, false otherwise.
-
inline bool is_from_this_host() const¶
Checks whether this guid is from a (Fast-DDS) entity created on this host (from where this method is called).
- Returns
true when this guid is from a (Fast-DDS) entity created on this host, false otherwise.
-
inline bool is_on_same_process_as(const GUID_t &other_guid) const¶
Checks whether this guid is for an entity on the same host and process as another guid.
Note
This method assumes the value of
other_guidwas originally assigned by Fast-DDS vendor.- Parameters
other_guid – GUID_t to compare to.
- Returns
true when this guid is on the same host and process, false otherwise.
-
inline bool is_from_this_process() const¶
Checks whether this guid is from a (Fast-DDS) entity created on this process (from where this method is called).
- Returns
true when this guid is from a (Fast-DDS) entity created on this process, false otherwise.
-
inline bool is_builtin() const¶
Checks whether this guid corresponds to a builtin entity.
- Returns
true when this guid corresponds to a builtin entity, false otherwise.
-
inline GUID_t() noexcept¶
