NAME

Ace::Browser::SiteDefs - Access to AceBrowser configuration files

SYNOPSIS

   use Ace;
   use Ace::Browser::AceSubs;
   use CGI qw(:standard);
 
   my $configuration = Configuration;
   my $docroot  = $configuration->Docroot;
   my @pictures = @{$configuration->Pictures};
   my %displays = %{$configuration->Displays};
   my $coderef  = $configuration->Url_mapper;
   $coderef->($param1,$param2);
 
 

DESCRIPTION

Ace::Browser::SiteDefs evaluates an AceBrowser configuration file and returns a configuration object (``config object'' for short). A config object is a bag of dynamically-generated methods, derived from the scalar variables, arrays, hashes and subroutines in the configuration file.

The config object methods are a canonicalized form of the configuration file variables, in which the first character of the method is uppercase, and subsequent characters are lower case. For example, if the configuration variable was $ROOT, the method will be $config_object->Root.

Working with Configuration Objects

To fetch a configuration object, use the Ace::Browser::AceSubs Configuration() function. This will return a configuration object for the current database:

   $config_object = Configuration();
 
 

Thereafter, it's just a matter of making the proper method calls.

    If the Configuration file is a....    The method call returns a...

    Scalar variable                       Scalar
    Array variable                        Array reference
    Hash variable                         Hash reference
    Subroutine                            Code reference
 
 

If a variable is not defined, the corresponding method will return undef.
