java.util.logging.SocketHandler

java.lang.Object
java.util.logging.Handler
java.util.logging.StreamHandler
java.util.logging.SocketHandler

A handler that writes log messages to a socket connection.

This handler reads the following properties from the log manager to initialize itself:

  • java.util.logging.ConsoleHandler.level specifies the logging level, defaults to Level.ALL if this property is not found or has an invalid value;
  • java.util.logging.SocketHandler.filter specifies the name of the filter class to be associated with this handler, defaults to null if this property is not found or has an invalid value;
  • java.util.logging.SocketHandler.formatter specifies the name of the formatter class to be associated with this handler, defaults to java.util.logging.XMLFormatter if this property is not found or has an invalid value;
  • java.util.logging.SocketHandler.encoding specifies the encoding this handler will use to encode log messages, defaults to null if this property is not found or has an invalid value.
  • java.util.logging.SocketHandler.host specifies the name of the host that this handler should connect to. There's no default value for this property.
  • java.util.logging.SocketHandler.encoding specifies the port number that this handler should connect to. There's no default value for this property.

This handler buffers the outgoing messages, but flushes each time a log record has been published.

This class is not thread-safe.
