NAME

       Tirex::Renderer - A Tirex renderer config

SYNOPSIS

       my $r = Tirex::Renderer->new( ... );

DESCRIPTION

       Tirex can work with several rendering backends such as Mapnik or WMS.  A backend can be
       started with different configurations, for the Mapnik backend you need to configure the
       font directory for instance. This class defines methods for reading the config files
       (/etc/tirex/renderer/*.conf) describing the backend configurations and managing those
       renderers.

       See the class Tirex::Backend and its subclasses for the actual code of some backends.

METHODS

   Tirex::Renderer->read_config_dir($dir)
       Read all renderer configs in given config directory.

   Tirex::Renderer->get('foo')
       Get renderer by name.

   Tirex::Renderer->all();
       Return sorted (by name) list of all configured renderers.

   Tirex::Renderer->clear();
       Clear list of renderers.

   Tirex::Renderer->enabled();
       Return sorted (by name) list of all enabled renderers.

   Tirex::Renderer->new( name => 'foo', path => '/path/to/exec', port => 1234, procs => 3, ... )
       Create new renderer config.

       Every renderer has at least these general options: name, path, port, and procs. Will croak
       if they are not all present.

       In addition it can have zero or more options specific to this renderer.

       Will croak if a renderer configuration already exists under the same name.

       Create new renderer config from a file.

       Croaks if the file does not exist.

   $rend->read_map_config()

       Return hash with renderer-specific configuration.

   $rend->get_name();
