SocketHandler
public class SocketHandler extends StreamHandler (Code)
Simple network logging Handler.

LogRecords are published to a network stream connection. By default the XMLFormatter class is used for formatting.

Configuration: By default each SocketHandler is initialized using the following LogManager configuration properties. If properties are not defined (or have invalid values) then the specified default values are used.

  • java.util.logging.SocketHandler.level specifies the default level for the Handler (defaults to Level.ALL).
  • java.util.logging.SocketHandler.filter specifies the name of a Filter class to use (defaults to no Filter).
  • java.util.logging.SocketHandler.formatter specifies the name of a Formatter class to use (defaults to java.util.logging.XMLFormatter).
  • java.util.logging.SocketHandler.encoding the name of the character set encoding to use (defaults to the default platform encoding).
  • java.util.logging.SocketHandler.host specifies the target host name to connect to (no default).
  • java.util.logging.SocketHandler.port specifies the target TCP port to use (no default).

The output IO stream is buffered, but is flushed after each LogRecord is written.
version:
   1.25, 05/05/07
since:
   1.4




Constructor Summary
public  SocketHandler()
     Create a SocketHandler, using only LogManager properties (or their defaults).
public  SocketHandler(String host, int port)
     Construct a SocketHandler using a specified host and port. The SocketHandler is configured based on LogManager properties (or their default values) except that the given target host and port arguments are used.

Method Summary
public synchronized  voidclose()
     Close this output stream.
public synchronized  voidpublish(LogRecord record)
     Format and publish a LogRecord.
Parameters:
  record - description of the log event.


Constructor Detail
SocketHandler
public SocketHandler() throws IOException(Code)
Create a SocketHandler, using only LogManager properties (or their defaults).
throws:
  IllegalArgumentException - if the host or port are invalid orare not specified as LogManager properties.
throws:
  IOException - if we are unable to connect to the targethost and port.


SocketHandler
public SocketHandler(String host, int port) throws IOException(Code)
Construct a SocketHandler using a specified host and port. The SocketHandler is configured based on LogManager properties (or their default values) except that the given target host and port arguments are used. If the host argument is empty, but not null String then the localhost is used.
Parameters:
  host - target host.
Parameters:
  port - target port.
throws:
  IllegalArgumentException - if the host or port are invalid.
throws:
  IOException - if we are unable to connect to the targethost and port.



Method Detail
close
public synchronized void close() throws SecurityException(Code)
Close this output stream.
exception:
  SecurityException - if a security manager exists and ifthe caller does not have LoggingPermission("control").


publish
public synchronized void publish(LogRecord record)(Code)
Format and publish a LogRecord.
Parameters:
  record - description of the log event. A null record issilently ignored and is not published
