Class std.socket.UdpSocket
UdpSocket
is a shortcut class for a UDP Socket.
Constructors
Name | Description |
---|---|
this
(family)
|
Constructs a blocking UDP Socket. |
this
()
|
Constructs a blocking IPv4 UDP Socket. |
Properties
Name | Type | Description |
---|---|---|
addressFamily [get]
|
AddressFamily | Get the socket's address family. |
blocking [get, set]
|
bool | Get/set socket's blocking flag. |
handle [get]
|
std | Get underlying socket handle. |
hostName [get]
|
string | |
isAlive [get]
|
bool | Property that indicates if this is a valid, alive socket. |
localAddress [get]
|
Address | Local endpoint Address .
|
remoteAddress [get]
|
Address | Remote endpoint Address .
|
Methods
Name | Description |
---|---|
accept
()
|
Accept an incoming connection. If the socket is blocking, accept
waits for a connection request. Throws SocketAcceptException if
unable to accept. See accepting for use with derived classes.
|
bind
(addr)
|
Associate a local address with this socket. |
close
()
|
Immediately drop any connections and release socket resources.
The Socket object is no longer usable after close .
Calling shutdown before close is recommended
for connection-oriented sockets.
|
connect
(to)
|
Establish a connection. If the socket is blocking, connect waits for the connection to be made. If the socket is nonblocking, connect returns immediately and the connection attempt is still in progress. |
factory
(classname)
|
Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor. |
getErrorText
()
|
Get a text description of this socket's error status, and clear the socket's error status. |
getOption
(level, option, result)
|
Get a socket option. |
getOption
(level, option, result)
|
Common case of getting integer and boolean options. |
getOption
(level, option, result)
|
Get the linger option. |
getOption
(level, option, result)
|
Get a timeout (duration) option. |
listen
(backlog)
|
Listen for an incoming connection. bind must be called before you
can listen . The backlog is a request of how many pending
incoming connections are queued until accept ed.
|
opCmp
(o)
|
Compare with another Object obj. |
opEquals
(o)
|
Test whether this is equal to o .
The default implementation only compares by identity (using the is operator).
Generally, overrides and overloads for opEquals should attempt to compare objects by their contents.
A class will most likely want to add an overload that takes your specific type as the argument
and does the content comparison. Then you can override this and forward it to your specific
typed overload with a cast. Remember to check for null on the typed overload.
|
receive
(buf, flags)
|
Receive data on the connection. If the socket is blocking, receive
waits until there is data to be received.
|
receiveFrom
(buf, flags, from)
|
Receive data and get the remote endpoint Address .
If the socket is blocking, receiveFrom waits until there is data to
be received.
|
select
(checkRead, checkWrite, checkError, timeout)
|
Wait for a socket to change status. A wait timeout of Duration or
TimeVal , may be specified; if a timeout is not specified or the
TimeVal is null , the maximum timeout is used. The TimeVal
timeout has an unspecified value when select returns.
|
send
(buf, flags)
|
Send data on the connection. If the socket is blocking and there is no
buffer space left, send waits.
|
sendTo
(buf, flags, to)
|
Send data to a specific destination Address. If the destination address is
not specified, a connection must have been made and that address is used.
If the socket is blocking and there is no buffer space left, sendTo waits.
|
setKeepAlive
(time, interval)
|
Enables TCP keep-alive with the specified parameters. |
setOption
(level, option, value)
|
Set a socket option. |
setOption
(level, option, value)
|
Common case for setting integer and boolean options. |
setOption
(level, option, value)
|
Set the linger option. |
setOption
(level, option, value)
|
Sets a timeout (duration) option, i.e. SocketOption or
RCVTIMEO . Zero indicates no timeout.
|
shutdown
(how)
|
Disables sends and/or receives. |
toHash
()
|
Compute hash function for Object. |
toString
()
|
Convert Object to a human readable string. |
accepting
()
|
Called by accept when a new Socket must be created for a new
connection. To use a derived class, override this method and return an
instance of your class. The returned Socket 's handle must not be
set; Socket has a protected constructor this() to use in this
situation.
|
createAddress
()
|
Can be overridden to support other addresses. |
