java.util.logging.Handler
java.util.logging.StreamHandler
java.util.logging.SocketHandler
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 where <handler-name>
 refers to the fully-qualified class name of the handler.
 If properties are not defined
 (or have invalid values) then the specified default values are used.
 
-    <handler-name>.level
        specifies the default level for the Handler(defaults toLevel.ALL).
-    <handler-name>.filter
        specifies the name of a Filterclass to use (defaults to noFilter).
-    <handler-name>.formatter
        specifies the name of a Formatterclass to use (defaults tojava.util.logging.XMLFormatter).
- <handler-name>.encoding the name of the character set encoding to use (defaults to the default platform encoding).
- <handler-name>.host specifies the target host name to connect to (no default).
- <handler-name>.port specifies the target TCP port to use (no default).
 For example, the properties for SocketHandler would be:
 
- java.util.logging.SocketHandler.level=INFO
- java.util.logging.SocketHandler.formatter=java.util.logging.SimpleFormatter
For a custom handler, e.g. com.foo.MyHandler, the properties would be:
- com.foo.MyHandler.level=INFO
- com.foo.MyHandler.formatter=java.util.logging.SimpleFormatter
 The output IO stream is buffered, but is flushed after each
 LogRecord is written.

Constructor Details- 
SocketHandlerCreate aSocketHandler, using onlyLogManagerproperties (or their defaults).- Throws:
- IllegalArgumentException- if the host or port are invalid or are not specified as LogManager properties.
- IOException- if we are unable to connect to the target host and port.
 
- 
SocketHandlerConstruct aSocketHandlerusing a specified host and port. TheSocketHandleris configured based onLogManagerproperties (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.
- port- target port.
- Throws:
- IllegalArgumentException- if the host or port are invalid.
- IOException- if we are unable to connect to the target host and port.
