NAME

WWW::Myspace::MyBase - Base class for WWW::Myspace modules

VERSION

Version 0.1

SYNOPSIS

This is a base class that can be used for all WWW::Myspace modules. It provides basic, standardized options parsing in several formats. It validates data using Params::Validate.

To use this in your new module, you simply subclass this module, add the "default_options" method to define your data, and write your methods.

package WWW::Myspace::MyModule;
use WWW::Myspace::MyBase -Base;

const default_options => { happiness => 1, # Required
		count => { default => 50 }, # Not required, defaults to 50
	};

field 'happiness';
field 'count';

sub mymethod {
	if ( $self->happiness ) { print "I'm happy" }
}


People can then call your method with:
$object = new WWW::Myspace::MyModule( happiness => 5 );

or

$object = new WWW::Myspace::MyModule( { happiness => 5 } );

See Params::Validate for more info on the format of, and available parsing stunts available in, default_options.

METHODS

default_options

This method returns a hashref of the available options and their default values. The format is such that it can be passed to Params::Validate (and, well it is :).

You MUST override this method to return your default options. Fortunately we use Spiffy, so you just have to do this:

const default_options => {
		option => { default => value },
		option => { default => value },
};

positional_parameters

If you need to use positional paramteres, define a "positional_parameters" method that returns a reference to a list of the parameter names in order, like this:

const positional_parameters => [ "username", "password" ];

new

Initialze and return a new object. $myspace is a WWW::Myspace object.

We accept the following formats: new - Just creates and returns the new object. new( $myspace ) - Where $myspace is a WWW::Myspace object. new( $myspace, $options_hashref ) - Myspace object followed by a hashref of option => value pairs new( $options_hashref ) new( %options ); new( @options ); - Each option passed is assigned in order to the keys of the "DEFAULT_OPTIONS" hash. new( 'config_file' => "/path/to/file", 'config_file_format' => 'YAML' ); - File format can be "YAML" (see YAML.pm) or "CFG" (see Config::General). - Defaults to "YAML" if not specified.

If you specify options and a config file, the config file will be read, and any options you explicitly passed will override the options read from the config file.

parse_options

This method is called by new to determine the format of the options passed and return a hash of option=>value pairs. If needed, you can call it yourself using the same formats described in "new" above.

$object->new;
$object->parse_options( 'username' => $username,
	'config_file' => "/path/to/file" );

read_config_file

This method is called by parse_options. If a "config_file" argument is passed, this method is used to read options from it. Currently supports CFG and YAML formats.

myspace

Sets/retreives the myspace object with which we're logged in. You probably don't need to use this as you'll pass it to the new method instead.

BUGS

Please report any bugs or feature requests to bug-www-myspace at rt.cpan.org, or through the web interface at http://rt.cpan.org/NoAuth/ReportBug.html?Queue=WWW-Myspace. I will be notified, and then you'll automatically be notified of progress on your bug as I make changes.

NOTES

You currently have to both specify the options in default_options and create accessor methods for those you want accessor methods for (i.e. all of them). This should be made less redundant.

We probably want to include cache_dir and possibile cache_file methods here.
