public Connection open(String protocol,
String name,
int mode,
boolean timeouts)
throws IOException
open in class ConnectionBasename - the target for the connection. It must be in this
format: "//mode - read/write mode of the connection (currently ignored).timeouts - A flag to indicate that the called wants timeout
exceptions (currently ignored).protocol - The URL protocol
IOException
ConnectionNotFoundException - If the connection cannot
be found.
public InputStream openInputStream()
throws IOException
openInputStream in interface InputConnectionopenInputStream in class ConnectionBaseIOException - if an I/O error occurs when creating the
input stream.
public OutputStream openOutputStream()
throws IOException
openOutputStream in interface OutputConnectionopenOutputStream in class ConnectionBaseIOException - if an I/O error occurs when creating the
output stream.
public void close()
throws IOException
close in interface Connectionclose in class ConnectionBaseIOException - if an I/O error occurs when closing the
connection.
public DataInputStream openDataInputStream()
throws IOException
openDataInputStream in interface InputConnectionopenDataInputStream in class ConnectionBaseIOException - If an I/O error occurs
public DataOutputStream openDataOutputStream()
throws IOException
openDataOutputStream in interface OutputConnectionopenDataOutputStream in class ConnectionBaseIOException - If an I/O error occurs
public void setSocketOption(byte option,
int value)
throws IllegalArgumentException,
IOException
SocketConnectionOptions inform the low level networking code about intended usage patterns that the application will use in dealing with the socket connection.
Calling setSocketOption to assign buffer sizes is a hint
to the platform of the sizes to set the underlying network I/O buffers.
Calling getSocketOption can be used to see what sizes the
system is using. The system MAY adjust the buffer sizes to account for
better throughput available from Maximum Transmission Unit (MTU) and
Maximum Segment Size (MSS) data available from current network
information.
setSocketOption in interface SocketConnectionoption - socket option identifier (KEEPALIVE, LINGER, SNDBUF, RCVBUF,
or DELAY)value - numeric value for specified option
IllegalArgumentException - if the value is not valid (e.g., negative value) or if the
option identifier is not valid
IOException - if the connection was closedSocketConnection.getSocketOption(byte)
public int getSocketOption(byte option)
throws IllegalArgumentException,
IOException
SocketConnection
getSocketOption in interface SocketConnectionoption - socket option identifier (KEEPALIVE, LINGER, SNDBUF, RCVBUF,
or DELAY)
IllegalArgumentException - if the option identifier is not valid
IOException - if the connection was closedSocketConnection.setSocketOption(byte, int)
public String getLocalAddress()
throws IOException
SocketConnectionThe host address(IP number) that can be used to connect to this end of the socket connection from an external system. Since IP addresses may be dynamically assigned, a remote application will need to be robust in the face of IP number reasssignment.
The local hostname (if available) can be accessed from
System.getProperty("microedition.hostname")
getLocalAddress in interface SocketConnectionIOException - if the connection was closed.ServerSocketConnection
public int getLocalPort()
throws IOException
SocketConnection
getLocalPort in interface SocketConnectionIOException - if the connection was closed.ServerSocketConnection
public String getAddress()
throws IOException
SocketConnection
getAddress in interface SocketConnectionIOException - if the connection was closed.
public int getPort()
throws IOException
SocketConnection
getPort in interface SocketConnectionIOException - if the connection was closed.
