Factory for generating DUIDs (DHCP Unique Identifiers).
Definition: duid_factory.h:63
bool isStored() const
Checks if generated DUID will be stored in the file.
Definition: duid_factory.cc:48
void createLLT(const uint16_t htype, const uint32_t time_in, const std::vector< uint8_t > &ll_identifier)
Generates DUID-LLT.
Definition: duid_factory.cc:53
void createEN(const uint32_t enterprise_id, const std::vector< uint8_t > &identifier)
Generates DUID-EN.
DuidPtr get()
Returns current DUID.
void createLL(const uint16_t htype, const std::vector< uint8_t > &ll_identifier)
Generates DUID-LL.
