NAME

Text::Same::MatchMap

DESCRIPTION

Objects of this class are returned by Text::Same::compare() and hold the results of comparison in a convenient form.

SYNOPSIS

 use Text::Same;
 use Text::Same::TextUI;

 my $matchmap = compare(\%options, $file1, $file2);

 if ($options{show_matches}) {
   my @matches = $matchmap->matches;

   for my $match (@matches) {
     if (!defined $options{min_score} or $match->score >= $options{min_score}) {
       print draw_match(\%options, $match);
     }
   }
 }

METHODS

See below. Methods private to this module are prefixed by an underscore.

new

 Title   : new
 Usage   : $matchmap = new Text::Same::MatchMap(options=>$options,
                                                source1=>$source1,
                                                source2=>$source2,
                                                seen_pairs=>\%seen_pairs);
 Function: Creates a new MatchMap object for a comparison
 Returns : A Text::Same::MatchMap object
 Args    : options - the options used by Text::Same::compare();
           source1 - a ChunkedSource for the first source
           source2 - a ChunkedSource for the second source
           seen_pairs - a hash from ChunkPair to Match object, used during
                        comparison to record which pairs of chunks (ie.
                        pairs of lines) have been assigned to a Match

source1

 Title   : source1
 Usage   : $source = $matchmap->source1();
 Function: returns the source1 argument to new()

source2

 Title   : source2
 Usage   : $source = $matchmap->source2();
 Function: returns the source2 argument to new()

matches

 Title   : matches
 Usage   : my @matches = $matches->matches();
 Function: return the Match objects from the seen_pairs argument to new()

source1_non_matches

 Title   : source1_non_matches
 Usage   : my @ranges = $matchmap->source1_non_matches();
 Function: return the ranges of chunks/lines from source1 that didn't match
           any lines from source2

source2_non_matches

 Title   : source2_non_matches
 Usage   : my @ranges = $matchmap->source2_non_matches();
 Function: return the ranges of chunks/lines from source2 that didn't match
           any lines from source1
