jdk.util.logging.SocketHandler — clojure-interop/java.util.logging 1.0.5

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 to Level.ALL). <handler-name>.filter specifies the name of a Filter class to use (defaults to no Filter). <handler-name>.formatter specifies the name of a Formatter class to use (defaults to java.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.

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.

host - target host. - java.lang.String port - target port. - int

throws: java.lang.IllegalArgumentException - if the host or port are invalid.

close clj

(close this)

Close this output stream.

throws: java.lang.SecurityException - if a security manager exists and if the caller does not have LoggingPermission("control").

publish clj

(publish this record)

Format and publish a LogRecord.

record - description of the log event. A null record is silently ignored and is not published - java.util.logging.LogRecord
