NAME

       Config::MVP::Reader - object to read config from storage into an assembler

VERSION

       version 2.200006

SYNOPSIS

         use Config::MVP::Reader::YAML; # this doesn't really exist

         my $reader   = Config::MVP::Reader::YAML->new;

         my $sequence = $reader->read_config('/etc/foobar.yml');

DESCRIPTION

       A Config::MVP::Reader exists to read configuration data from storage (like a file) and
       convert that data into instructions to a Config::MVP::Assembler, which will in turn
       convert them into a Config::MVP::Sequence, the final product.

METHODS

   read_config
         my $sequence = $reader->read_config($location, \%arg);

       This method is passed a location, which has no set meaning, but should be the mechanism by
       which the Reader is told how to locate configuration.  It might be a file name, a hashref
       of parameters, a DBH, or anything else, depending on the needs of the specific Reader
       subclass.

       It is also passed a hashref of arguments, of which there is only one valid argument:

        assembler - the Assembler object into which to read the config

       If no assembler argument is passed, one will be constructed by calling the Reader's
       "build_assembler" method.

       Subclasses should generally not override "read_config", but should instead implement a
       "read_into_assembler" method, described below.

   read_into_assembler
       This method should not be called directly.  It is called by "read_config" with the
       following parameters:

         my $sequence = $reader->read_into_assembler( $location, $assembler );

       The method should read the configuration found at $location and use it to instruct the
       $assembler (a Config::MVP::Assembler) what configuration to perform.

       The default implementation of this method will throw an exception complaining that it
       should have been implemented by a subclass.

   build_assembler
       If no Assembler is provided to "read_config"'s "assembler" parameter, this method will be
       called on the Reader to construct one.

       It must return a Config::MVP::Assembler object, and by default will return an entirely
       generic one.
