Flush any buffered messages.

  Return the character encoding for this Handler.

  Return the character encoding for this Handler.
Returns: The encoding name. May be null, which indicates the default encoding should be used.

  Retrieves the ErrorManager for this Handler.

  Retrieves the ErrorManager for this Handler.
Throws:
- SecurityException - if a security manager exists and if the caller does not have LoggingPermission("control").

  Get the current Filter for this Handler.

  Get the current Filter for this Handler.
Returns: a Filter object (may be null)

  Return the Formatter for this Handler.

  Return the Formatter for this Handler.
Returns: the Formatter (may be null).

  Get the log level specifying which messages will be logged by this Handler.

  Get the log level specifying which messages will be
logged by this Handler. Message levels lower
than this level will be discarded.
Returns: the level of messages being logged.

  Check if this Handler would actually log a given LogRecord.

  Check if this Handler would actually log a given LogRecord.

This method checks if the LogRecord has an appropriate level and whether it satisfies any Filter. It will also return false if no output stream has been assigned yet or the LogRecord is Null.

Returns: true if the LogRecord would be logged.
Parameters:
- record - a LogRecord

  Protected convenience method to report an error to this Handler's ErrorManager.

  Protected convenience method to report an error to this Handler's
ErrorManager. Note that this method retrieves and uses the ErrorManager
without doing a security check. It can therefore be used in
environments where the caller may be non-privileged.
Parameters:
- msg - a descriptive string (may be null)
- ex - an exception (may be null)
- code - an error code defined in ErrorManager

  Set (or change) the character encoding used by this Handler.

  Set (or change) the character encoding used by this Handler.

The encoding should be set before any LogRecords are written to the Handler.
Parameters:
- encoding - The name of a supported character encoding. May be null, to indicate the default platform encoding.
Throws:
- SecurityException - if a security manager exists and if the caller does not have LoggingPermission("control").
- UnsupportedEncodingException - if the named encoding is not supported.

  Define an ErrorManager for this Handler.

  Define an ErrorManager for this Handler.

The ErrorManager's "error" method will be invoked if any errors occur while using this Handler.
Parameters:
- em - the new ErrorManager
Throws:
- SecurityException - if a security manager exists and if the caller does not have LoggingPermission("control").

  Set a Filter to control output on this Handler.

  Set a Filter to control output on this Handler.

For each call of publish the Handler will call this Filter (if it is non-null) to check if the LogRecord should be published or discarded.
Parameters:
- newFilter - a Filter object (may be null)
Throws:
- SecurityException - if a security manager exists and if the caller does not have LoggingPermission("control").

  Set a Formatter.

  Set a Formatter. This Formatter will be used to format LogRecords for this Handler.

Some Handlers may not use Formatters, in which case the Formatter will be remembered, but not used.

Parameters:
- newFormatter - the Formatter to use (may not be null)
Throws:
- SecurityException - if a security manager exists and if the caller does not have LoggingPermission("control").

  Set the log level specifying which message levels will be logged by this Handler.

  Set the log level specifying which message levels will be logged by this Handler. Message levels lower than this value will be discarded.

The intention is to allow developers to turn on voluminous logging, but to limit the messages that are sent to certain Handlers.
Parameters:
- newLevel - the new value for the log level
Throws:
- SecurityException - if a security manager exists and if the caller does not have LoggingPermission("control").

  Change the output stream.

  Change the output stream.

If there is a current output stream then the Formatter's tail string is written and the stream is flushed and closed. Then the output stream is replaced with the new output stream.
Parameters:
- out - New output stream. May not be null.
Throws:
- SecurityException - if a security manager exists and if the caller does not have LoggingPermission("control").
