java.util.logging
public class SocketHandler extends StreamHandler
SocketHandler publishes log records to
a TCP/IP socket.
Configuration: Values of the subsequent
LogManager properties are taken into consideration
when a SocketHandler is initialized.
If a property is not defined, or if it has an invalid
value, a default is taken without an exception being thrown.
java.util.SocketHandler.level - specifies
the initial severity level threshold. Default value:
Level.ALL.java.util.SocketHandler.filter - specifies
the name of a Filter class. Default value: No Filter.java.util.SocketHandler.formatter - specifies
the name of a Formatter class. Default value:
java.util.logging.XMLFormatter.java.util.SocketHandler.encoding - specifies
the name of the character encoding. Default value:
the default platform encoding.java.util.SocketHandler.host - specifies
the name of the host to which records are published.
There is no default value for this property; if it is
not set, the SocketHandler constructor will throw
an exception.java.util.SocketHandler.port - specifies
the TCP/IP port to which records are published.
There is no default value for this property; if it is
not set, the SocketHandler constructor will throw
an exception.| Constructor Summary | |
|---|---|
| SocketHandler()
Constructs a SocketHandler that publishes log
records to a TCP/IP socket. | |
| SocketHandler(String host, int port)
Constructs a SocketHandler that publishes log
records to a TCP/IP socket. | |
| Method Summary | |
|---|---|
| void | publish(LogRecord record)
Publishes a LogRecord to the network socket,
provided the record passes all tests for being loggable.

SocketHandler that publishes log
records to a TCP/IP socket. Tthe initial configuration is
determined by the LogManager properties described
above.
Throws: java.io.IOException if the connection to the specified
network host and port cannot be established.
java.lang.IllegalArgumentException if either the
java.util.logging.SocketHandler.host
or java.util.logging.SocketHandler.port
LogManager properties is not defined, or specifies
an invalid value.
SocketHandler that publishes log
records to a TCP/IP socket. With the exception of the internet
host and port, the initial configuration is determined by the
LogManager properties described above.
Parameters: host the Internet host to which log records will be forwarded. port the port at the host which will accept a request for a TCP/IP connection.
Throws: java.io.IOException if the connection to the specified
network host and port cannot be established.
java.lang.IllegalArgumentException if either
host or port specify
an invalid value.
LogRecord to the network socket,
provided the record passes all tests for being loggable.
In addition, all data that may have been buffered will
be forced to the network stream.
Most applications do not need to call this method directly. Instead, they will use a {@link Logger} instance, which will create LogRecords and distribute them to registered handlers.
In case of an I/O failure, the ErrorManager
of this SocketHandler will be informed, but the caller
of this method will not receive an exception.
Parameters: record the log event to be published.
