Constructors
Record
Record();
Creates an empty Record.
Record
Record(
const std::string & name,
Poco::UInt16 type,
Poco::UInt16 length,
const void * data,
Poco::UInt32 ttl = 0
);
Creates the Record using the given information.
- name specifies the full domain name of the record.
- type specifies the record's type (e.g., RT_PTR). Suitable values can be found in the RecordType enumeration.
- length specifies the length in bytes of the record's data.
- data points to the actual data. This pointer must be valid for the entire lifetime of the Record object, as it's content is not copied.
- ttl specifies the time-to-live of the record in seconds. If ttl is 0, the system will chose an appropriate value.
The record class is set to RT_IN.
Record
Record(
Poco::Int32 networkInterface,
const std::string & name,
Poco::UInt16 type,
Poco::UInt16 clazz,
Poco::UInt16 length,
const void * data,
Poco::UInt32 ttl
);
Creates the Record using the given information.
- networkInterface specifies the index of the interface the record was discovered on.
- name specifies the full domain name of the record.
- type specifies the record's type (e.g., RT_PTR). Suitable values can be found in the RecordType enumeration.
- clazz specifies the record's class (usually RC_IN).
- length specifies the length in bytes of the record's data.
- data points to the actual data. This pointer must be valid for the entire lifetime of the Record object, as it's content is not copied.
- ttl specifies the time-to-live of the record in seconds.
Destructor
~Record
~Record();
Destroys the Service.
