Method Details

unwrap

public static AFGenericSocketAddress unwrap(InetAddress address,
 int port)
                                     throws SocketException

Returns an AFGenericSocketAddress given a special InetAddress that encodes the byte sequence of an unknown-type socket address, like those returned by AFSocketAddress.wrapAddress().

Parameters:

address - The "special" InetAddress.

port - The port (use 0 for "none").

Returns:

The AFGenericSocketAddress instance.

Throws:

SocketException - if the operation fails, for example when an unsupported address is specified.

unwrap

public static AFGenericSocketAddress unwrap(String hostname,
 int port)
                                     throws SocketException

Returns an AFGenericSocketAddress given a special InetAddress hostname that encodes the byte sequence of an unknown-type socket address, like those returned by AFSocketAddress.wrapAddress().

Parameters:

hostname - The "special" hostname, as provided by InetAddress.getHostName().

port - The port (use 0 for "none").

Returns:

The AFGenericSocketAddress instance.

Throws:

SocketException - if the operation fails, for example when an unsupported address is specified.

unwrap

public static AFGenericSocketAddress unwrap(SocketAddress address)
                                     throws SocketException

Returns an AFGenericSocketAddress given a generic SocketAddress.

Parameters:

address - The address to unwrap.

Returns:

The AFGenericSocketAddress instance.

Throws:

SocketException - if the operation fails, for example when an unsupported address is specified.

toString

public String toString()

Overrides:

toString in class InetSocketAddress

toBytes

public byte[] toBytes()

Returns the native representation of this generic address, which is most likely not portable.

The address contains the sa_family identifier as the first byte, and, on some platforms only, the address length, as the second byte.

Returns:

A new byte array containing the system-specific representation of that address.

hasFilename

public boolean hasFilename()

Description copied from class: AFSocketAddress

Checks if the address can be resolved to a File.

Specified by:

hasFilename in class AFSocketAddress

Returns:

true if the address has a filename.

getFile

public File getFile()
             throws FileNotFoundException

Description copied from class: AFSocketAddress

Returns the File corresponding with this address, if possible. A FileNotFoundException is thrown if there is no filename associated with the address, which applies to addresses in the abstract namespace, for example.

Specified by:

getFile in class AFSocketAddress

Returns:

The filename.

Throws:

FileNotFoundException - if the address is not associated with a filename.

isSupportedAddress

public static boolean isSupportedAddress(InetAddress addr)

Checks if an InetAddress can be unwrapped to an AFGenericSocketAddress.

Parameters:

addr - The instance to check.

Returns:

true if so.

See Also:

• AFSocketAddress.wrapAddress()
• unwrap(InetAddress, int)

isSupportedAddress

public static boolean isSupportedAddress(SocketAddress addr)

Checks if a SocketAddress can be unwrapped to an AFGenericSocketAddress.

Parameters:

addr - The instance to check.

Returns:

true if so.

See Also:

• unwrap(InetAddress, int)

addressFamily

public static AFAddressFamily<AFGenericSocketAddress> addressFamily()

Returns the corresponding AFAddressFamily.

Returns:

The address family instance.

of

public static AFGenericSocketAddress of(URI uri)
                                 throws SocketException

Returns an AFGenericSocketAddress for the given URI, if possible.

Parameters:

uri - The URI.

Returns:

The address.

Throws:

SocketException - if the operation fails.

of

public static AFGenericSocketAddress of(URI uri,
 int overridePort)
                                 throws SocketException

Returns an AFGenericSocketAddress for the given URI, if possible.

Parameters:

uri - The URI.

overridePort - The port to forcibly use, or -1 for "don't override".

Returns:

The address.

Throws:

SocketException - if the operation fails.

toURI

public URI toURI(String scheme,
 URI template)
          throws IOException

Description copied from class: AFSocketAddress

Tries to create a URI based on this AFSocketAddress.

Overrides:

toURI in class AFSocketAddress

Parameters:

scheme - The target scheme.

template - An optional template to reuse certain parameters (e.g., the "path" component for an http request), or null.

Returns:

The URI.

Throws:

IOException - on error.
