NAME ^

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

DEPRECATED ^

The KinoSearch code base has been assimilated by the Apache Lucy project. The "KinoSearch" namespace has been deprecated, but development continues under our new name at our new home: http://lucy.apache.org/

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 ^

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
    );
