               'Dispatch', dispatcher => $log );

DESCRIPTION

       The "Log-Any-Adapter" distribution implements Log::Any class methods to specify where logs should be
       sent. It is a separate distribution so as to keep "Log::Any" itself as simple and unchanging as possible.

       You do not have to use anything in this distribution explicitly. It will be auto-loaded when you call one
       of the methods below.

ADAPTERS

       In order to use a logging mechanism with "Log::Any", there needs to be an adapter class for it. Typically
       this is named Log::Any::Adapter::something.

   Adapters in this distribution
       Three basic adapters come with this distribution -- File, Stdout and Stderr:

           use Log::Any::Adapter ('File', '/path/to/file.log');
           use Log::Any::Adapter ('Stdout');
           use Log::Any::Adapter ('Stderr');

           # or

           use Log::Any::Adapter;
           Log::Any::Adapter->set('File', '/path/to/file.log');
           Log::Any::Adapter->set('Stdout');
           Log::Any::Adapter->set('Stderr');

       All of them simply output the message and newline to the specified destination; a datestamp prefix is
       added in the "File" case. For anything more complex you'll want to use a more robust adapter from CPAN.

   Adapters on CPAN
       A sampling of adapters available on CPAN as of this writing:

       •   Log::Any::Adapter::Log4perl

       •   Log::Any::Adapter::Dispatch

       •   Log::Any::Adapter::FileHandle

       •   Log::Any::Adapter::Syslog

       You may find other adapters on CPAN by searching for "Log::Any::Adapter", or create your own adapter. See
       Log::Any::Adapter::Development for more information on the latter.

SETTING AND REMOVING ADAPTERS

       Log::Any::Adapter->set ([options, ]adapter_name, adapter_params...)
           This method sets the adapter to use for all log categories, or for a particular set of categories.

           adapter_name is the name of an adapter. It is automatically prepended with "Log::Any::Adapter::". If
           instead you want to pass the full name of an adapter, prefix it with a "+". e.g.

               # Use My::Adapter class
               Log::Any::Adapter->set('+My::Adapter', arg => $value);

           adapter_params are passed along to the adapter constructor. See the documentation for the individual
           adapter classes for more information.

           An optional hash of options may be passed as the first argument. Options are:

           category
               A string containing a category name, or a regex (created with qr//) matching multiple categories.
               If not specified, all categories will be affected.

           lexically
               A reference to a lexical variable. When the variable goes out of scope, the adapter setting will
               be removed. e.g.

                   {
                       Log::Any::Adapter->set({lexically => \my $lex}, ...);

                       # in effect here
                       ...
                   }
                   # no longer in effect here

           "set" returns an entry object, which can be passed to "remove".

       use Log::Any::Adapter (...)
           If you pass arguments to "use Log::Any::Adapter", it calls "Log::Any::Adapter->set" with those
           arguments.

       Log::Any::Adapter->remove (entry)
           Remove an entry previously returned by "set".

MULTIPLE ADAPTER SETTINGS

       "Log::Any" maintains a stack of entries created via "set".

       When you get a logger for a particular category, "Log::Any" will work its way down the stack and use the
       first matching entry.

       Whenever the stack changes, any "Log::Any" loggers that have previously been created will automatically
       adjust to the new stack. For example:

           my $log = Log::Any->get_logger();
           $log->error("aiggh!");   # this goes nowhere
           ...
           {
               Log::Any::Adapter->set({ lexically => \my $lex }, 'Log4perl');
               $log->error("aiggh!");   # this goes to log4perl
               ...
           }
           $log->error("aiggh!");   # this goes nowhere again
