Lucy::Search::Span(3pm)

Usage

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

Overview

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

`•`	`offset` - Integer offset, unit is context-dependent.
`•`	`length` - Integer length, unit is context-dependent.
`•`	`weight` - A floating point weight.
