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_guid was 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_guid was 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 explicit operator const InstanceHandle_t&() const
