Interface SocketOptions
- DatagramSocketImpl, NIOSocketImpl, PlainDatagramSocketImpl, PlainSocketImpl, SocketImpl
This interface is used by SocketImpl and
DatagramSocketImpl to implement options
on sockets.
static int | IP_MULTICAST_IF- Options id for the IP_MULTICAST_IF value
|
static int | IP_MULTICAST_IF2- same as above
|
static int | IP_MULTICAST_LOOP- This option enables or disables local loopback of multicast datagrams.
|
static int | IP_TOS- This option sets the type-of-service or traffic class field in the
IP header for a TCP or UDP socket.
|
static int | SO_BINDADDR- Retrieve the local address to which the socket is bound.
|
static int | SO_BROADCAST- Sets SO_BROADCAST for a socket
|
static int | SO_KEEPALIVE- Option id for the SO_KEEPALIVE value
|
static int | SO_LINGER- Option id for the SO_LINGER value
|
static int | SO_OOBINLINE- Sets SO_OOBINLINE for a socket
|
static int | SO_RCVBUF- Option id for the receive buffer size
|
static int | SO_REUSEADDR- Sets the SO_REUSEADDR parameter on a socket
|
static int | SO_SNDBUF- Option id for the send buffer size
|
static int | SO_TIMEOUT- Option id for the SO_TIMEOUT value
|
static int | TCP_NODELAY- Option id for the TCP_NODELAY value
|
Object | getOption(int optionId)- Returns the current setting of the specified option.
|
void | setOption(int optionId, Object val)- Sets the specified option on a socket to the passed in object.
|
getOption
public Object getOption(int optionId)
throws SocketException Returns the current setting of the specified option. The
Object returned will be an Integer for options
that have integer values. For options that are set to on or off, a
Boolean will be returned. The optionId
parameter is one of the defined constants in this interface.
optionId - The option identifier
- The current value of the option
setOption
public void setOption(int optionId,
Object val)
throws SocketException Sets the specified option on a socket to the passed in object. For
options that take an integer argument, the passed in object is an
Integer. For options that are set to on or off, the
value passed will be a Boolean. The optionId
parameter is one of the defined constants in this interface.
optionId - The identifier of the optionval - The value to set the option to
