NAME

PFT::Map::Resolver - Resolve symbols in PFT Entries

SYNOPSIS

    use PFT::Map::Resolver 'resolve';

    die unless $map->isa('PFT::Map');
    die unless $node->isa('PFT::Map::Node');
    die unless $sym->isa('PFT::Text::Symbol');

DESCRIPTION

This module only exports one function, named resolve.

The function resolves a symbol retrieved from the text of a PFT::Map::Node. The returned value will be one of the following:

A node (i.e. a PFT::Map::Node instance);

A string (e.g. http://manpages.org);

The undef value (meaning: failed resolution).
