public class SocketHandler
extends StreamHandler
```
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.
