Handel::ConfigReader 1.00005

Handel::ConfigReader can read in Handel configuration settings from ENV/ModPerl.

SYNOPSIS

use Handel::ConfigReader;

my $cfg = Handel::ConfigReader->instance();
my $setting = $cfg->get('HandelMaxQuantity');
my $other = $cfg->{'OtherSetting'};

Handel::ConfigReader is a generic wrapper to get various configuration values. As some point this will probably get worked into XS/custom httpd.conf directives.

Each configuration object is also a tied hash. The two usages are the same:

my $cfg = Handel::ConfigReader->instance();

my $setting = $cfg->get('Setting');
my $setting = $cfg->{'Setting'};

The latter is the preferred usage in anticipation of also integrating Apache::ModuleConfig and custom directives which use the same hash syntax.

CONSTRUCTOR

new

Returns a new Handel::ConfigReader instance.

my $cfg = Handel::ConfigReader->new();

instance

Returns the same Handel::ConfigReader instance for each call.

my $cfg = Handel::ConfigReader->instance();

METHODS

get

Arguments: $key [, $default]

Returns the configured value for the key specified. You can use this as an instance method or as a simpleton:

my $cfg = Handel::ConfigReader->instance();
my $setting = $cfg->get('HandelMaxQuantity');

my $cfg = Handel::ConfigReader->instance();
my $setting = $cfg->get('HandelMaxQuantity');

You can also pass a default value as the second parameter. If no value is loaded for the key specified, the default value will be returned instead.

my $cfg = Handel::ConfigReader->instance();
my $setting = $cfg->get('DoesNotExist', 'foo');
print $setting; # foo

FETCH

Arguments: $key

Returns an item form the configuration via tied hash.

my $cfg = Handel::ConfigReader->new;
my $setting = $cfg->{'MySetting'};

EXISTS

Arguments: $key

Returns true if the specified setting returns a defined value.

my $cfg = Handel::ConfigReader->new;
if (exists $cfg->{'MySetting'}) {
...
};
