NAME
       Net::DRI::Logging - Logging Operations for Net::DRI


VERSION
       This documentation refers to Net::DRI::Logging version 1.02


SYNOPSIS
       This module is never used directly, only its subclasses are used. See the subclasses documentation:
       Net::DRI::Logging::Files, Net::DRI::Logging::Null and Net::DRI::Logging::Stderr.  See also Net::DRI
       documentation and its "logging()" method.


DESCRIPTION
       This is the superclass of all logging modules (under the Net::DRI::Logging::* namespace).


EXAMPLES
       See Net::DRI documentation.


SUBROUTINES/METHODS
       This is mostly a pure virtual superclass. All subclasses should have the following methods:

       new()
           a ref hash is passed with some keys ; besides keys specifically related to the logging class used,
           some keys are (or should be) understood by all clases.

           They are:

           level
               current level of logging (no messages below this level would be dumped), between: debug info
               notice warning error critical alert emergency ; default: warning

               It can be changed anytime later by using the level() method

           xml_indent
               0 or 1 depending if you want your XML strings to be dumped as a long line (0) or indented for
               humans (1) ; default: 0

           encoding
               if needed, name of encoding to use to convert data stream ; default: UTF-8

       name()
           returns the name as string of the logging modules

       setup_channel(SOURCE,TYPE,DATA)
           prepare for a new channel of data comming from SOURCE (package name), of TYPE ; DATA is a ref hash of
           additional parameter, such as filenames, etc.

       output(LEVEL,TYPE,DATA1,DATA2,...)
           add data to channel type TYPE at level LEVEL ('debug', 'info', 'notice', etc.) ; DATA is a ref hash
           with all data to log or a simple string (the message) ; the logging module should know what to do
           with it and how to format it (which may depend on the TYPE attribute, which itself is tied to the
           SOURCE attribute of "setup_channel()").


DIAGNOSTICS
       None.


CONFIGURATION AND ENVIRONMENT
       See the "new()" method.


DEPENDENCIES
       This module has to be used inside the Net::DRI framework and needs the following components:

       Net::DRI::BaseClass
       Net::DRI::Util
       Net::DRI::Exception


INCOMPATIBILITIES
       None.


BUGS AND LIMITATIONS
       No known bugs. Please report problems to author (see below) or use CPAN RT system. Patches are welcome.

       The interface could be later changed to suit Log::Log4Perl or other Perl standard logging modules, if
       needed.

       Other subclasses should be created to cater for other logging destinations (such as a RDBMS).

       Net::DRI expects these logging modules to be non-blocking and returning immediately.

       This logging framework is currently only used by Net::DRI::Transport::Socket, it should get applied to
       other transports and other internal parts of Net::DRI.

       When LocalStorage do appear inside Net::DRI, logging should probably use it (TODO).
