18.2.3.8.2. GuidPrefix_t

struct GuidPrefix_t

Structure GuidPrefix_t, Guid Prefix of GUID_t.

Public Functions

inline GuidPrefix_t()

Default constructor. Set the Guid prefix to 0.

bool is_on_same_host_as(const GuidPrefix_t &other_guid_prefix) const

Checks whether this guid prefix is from an entity on the same host as another guid prefix.

Note

This method assumes the value of other_guid_prefix was originally assigned by Fast-DDS vendor.

Parameters

other_guid_prefix – GuidPrefix_t to compare to.

Returns

true when this guid prefix is on the same host, false otherwise.

bool is_from_this_host() const

Checks whether this guid prefix is from a (Fast-DDS) entity created on this host (from where this method is called).

Returns

true when this guid prefix is from a (Fast-DDS) entity created on this host, false otherwise.

bool is_on_same_process_as(const GuidPrefix_t &other_guid_prefix) const

Checks whether this guid prefix is for an entity on the same host and process as another guid prefix.

Note

This method assumes the value of other_guid_prefix was originally assigned by Fast-DDS vendor.

Parameters

other_guid_prefix – GuidPrefix_t to compare to.

Returns

true when this guid prefix is on the same host and process, false otherwise.

bool is_from_this_process() const

Checks whether this guid prefix is from a (Fast-DDS) entity created on this host and process (from where this method is called).

Returns

true when this guid prefix is from a (Fast-DDS) entity created on this host and process, false otherwise.

inline bool operator==(const GuidPrefix_t &prefix) const

Guid prefix comparison operator

Parameters

prefix – guid prefix to compare

Returns

True if the guid prefixes are equal

inline bool operator!=(const GuidPrefix_t &prefix) const

Guid prefix comparison operator

Parameters

prefix – Second guid prefix to compare

Returns

True if the guid prefixes are not equal

inline bool operator<(const GuidPrefix_t &prefix) const

Guid prefix minor operator

Parameters

prefix – Second guid prefix to compare

Returns

True if prefix is higher than this

Public Static Functions

static inline int cmp(const GuidPrefix_t &prefix1, const GuidPrefix_t &prefix2)

Guid Prefix compare static method.

Parameters

• prefix1 – First guid prefix to compare

• prefix2 – Second guid prefix to compare

Returns

0 if prefix1 is equal to prefix2 .

Returns

< 0 if prefix1 is lower than prefix2 .

Returns

> 0 if prefix1 is higher than prefix2 .
