Basic Sockets - TCP/IP Sockets in Java Practical Guide for Programmers - page 17

InetAddress getLocalAddress ()
int getLocalPort ()
Returns the local socket address/port.

int getReceiveBufferSize ()
int getSendBufferSize ()
void setReceiveBufferSize ( int size )
void setSendBufferSize ( int size )
Returns/sets the size of the send/receive buffer for the socket (see Section 4.4).
size Number of bytes to allocate for the socket send/receive

buffer

int getSoLinger ()
void setSoLinger ( boolean on , int linger )
Returns/sets the maximum amount of time (in milliseconds) that close() will block
waiting for all data to be delivered. getSoLinger() returns − 1 if lingering is disabled
(see Section 5.4). Lingering is off by default.
on If true , the socket lingers on close() . up to the maximum

specified time.

linger The maximum amount of time (milliseconds) a socket lingers

on close()

int getSoTimeout ()
void setSoTimeout ( int timeout )
Returns/sets the maximum amount of time that a read() on this socket will block. If
the specified number of milliseconds elapses before any data is available, an Inter−
ruptedIOException is thrown (see Section 4.2).
timeout

The maximum time (milliseconds) to wait for data on a
read() . The value 0 (the default) indicates that there is no
time limit, meaning that a read will not return until data is
available.

boolean getTcpNoDelay ()
void setTcpNoDelay ( boolean on )
Returns/sets whether the Nagle algorithm to coalesce TCP packets is disabled. To avoid
small TCP packets, which make inecient use of network resources, Nagle's algorithm
(enabled by default) delays packet transmission under certain conditions to improve
the opportunities to coalesce bytes from several writes into a single TCP packet. This
delay is unacceptable to some types of interactive applications.
on

If true ( false ), disable (enable) Nagle's algorithm.
