Public Methods
public boolean equals(Object obj)
Compares the specified object to this NetworkInterface and answer if they
are equal. The object must be an instance of NetworkInterface with the
same name, displayName and list of network interfaces to be the same
Parameters
| obj | the object to compare |
|---|
Returns
- true if the specified object is equal to this NetworkInterfcae, false otherwise
See Also
public static NetworkInterface getByInetAddress(InetAddress address)
Answers the network interface which has the specified internet address
bound to it, if one exists.
Parameters
| address | address of interest |
|---|
Returns
- network interface for internet address specified if it exists, otherwise null
Throws
| SocketException | if an error occurs when getting network interface information |
|---|---|
| NullPointerException | if the address passed in is null |
public static NetworkInterface getByName(String interfaceName)
Answers the network interface with the specified name, if one exists
Returns
- network interface for name specified if it exists, otherwise null
Throws
| SocketException | if an error occurs when getting network interface information |
|---|---|
| NullPointerException | if the interface name passed in is null |
public String getDisplayName()
Answers the user readable name associated with the network interface
Returns
- display name associated with the network interface or null if one is not available
public Enumeration getInetAddresses()
Answers the list of internet addresses bound to the interface
Returns
- list of internet addresses bound to the interface
public String getName()
Answers the name associated with the network interface
Returns
- name associated with the network interface
public static Enumeration getNetworkInterfaces()
Answers the list of network interfaces supported by the system or null if
no interfaces are supported by the system
Returns
- Enumeration containing one NetworkInterface object for each interface supported by the system
Throws
| SocketException | if an error occurs when getting network interface information |
|---|
public int hashCode()
Answers a hash code for this NetworkInterface object. Since the name
should be unique for each network interface the hash code is generated
using this name
Returns
- the hashcode for hashtable indexing
public String toString()
Answers a string containing a concise, human-readable description of the
network interface
Returns
- a printable representation for the network interface
