SocketHandlerjava.util.logging

Java 1.4

This Handler subclass formats LogRecord objects and outputs the resulting strings to a network socket. When you create a SocketHandler, you can pass the hostname and port of the socket to the constructor or you can rely on system-wide defaults obtained with LogManager.getProperty( ). SocketHandler also uses LogManager.getProperty( ) to obtain initial values for the properties inherited from Handler. The table below lists these properties, as well as the host and port arguments, the value passed to getProperty( ), and the default value used if getProperty( ) returns null. See Handler for further details.
