Java.net.Inet4Address klasa u Javi
Ova klasa proširuje klasu InetAddress i predstavlja IPv4 adresu. Pruža metode za tumačenje i prikaz korisnih informacija o IP adresama.
Metode ove klase unose se u 4 formata:
metode:
| Metode | Opis |
|---|---|
| jednako (Object obj) | Ova metoda uspoređuje ovaj objekt s navedenim objektom. |
| getAddress() | Ova metoda vraća neobrađenu IP adresu ovog InetAddress objekta. |
| getHostAddress() | Ova metoda vraća niz IP adrese u obliku tekstualne prezentacije. |
| hashCode() | Ova metoda vraća hashcode za ovu IP adresu. |
| isAnyLocalAddress() | Ova rutinska pomoćna metoda provjerava je li InetAddress adresa sa zamjenskim znakovima. |
| isLinkLocalAddress() | Ova rutinska pomoćna metoda provjerava je li InetAddress lokalna adresa veze. |
| isLoopbackAddress() | Ova rutinska pomoćna metoda provjerava je li InetAddress povratna adresa. |
| isMCGlobal() | Ova rutinska pomoćna metoda provjerava ima li multicast adresa globalni opseg. |
| isMCLinkLocal() | Ova rutinska pomoćna metoda provjerava ima li multicast adresa opseg veze. |
| isMCNodeLocal() | Ova rutinska pomoćna metoda provjerava ima li multicast adresa opseg čvora. |
| isMCOrgLocal() | Ova rutina pomoćnog programa za provjeru ima li multicast adresa organizacijski opseg. |
| isMCSiteLocal() | Ova rutinska pomoćna metoda provjerava ima li multicast adresa opseg stranice. |
| isMulticastAddress() | Ova rutinska pomoćna metoda provjerava je li InetAddress IP multicast adresa. |
| isSiteLocalAddress() | Ova rutinska pomoćna metoda provjerava je li InetAddress lokalna adresa stranice. |
