NAME

KinoSearch::Search::Span - An offset, a length, and a weight.

SYNOPSIS

            

              
              
my $combined_length = $upper_span->get_length
    + ( $upper_span->get_offset - $lower_span->get_offset );
my $combined_span = KinoSearch::Search::Span->new(
    offset => $lower_span->get_offset,
    length => $combined_length,
);
...
            
          

DESCRIPTION

An offset, a length, and a weight.

Span objects store information about a span across an array of... something. The unit is context-dependent.

Text is one possibility, in which case offset and length might be measured in Unicode code points. However, the Span could also refer to a span within an array of tokens, for example -- in which case the start and offset might be measured in token positions.

CONSTRUCTORS

new( [labeled params] )

            

              
              
my $span = KinoSearch::Search::Span->new(
    offset => 75,     # required
    length => 7,      # required
    weight => 1.0,    # default 0.0
);
            
          

• offset - Integer offset, unit is context-dependent.
