NAME

Search::Tools::Token - a token object returned from a TokenList

SYNOPSIS

 use Search::Tools::Tokenizer;
 my $tokenizer = Search::Tools::Tokenizer->new();
 my $tokens = $tokenizer->tokenize('quick brown red dog');
 while ( my $token = $tokens->next ) {
     # token isa Search::Tools::Token
     print "token = $token\n";
     printf("str: %s, len = %d, u8len = %d, pos = %d, is_match = %d, is_hot = %d\n",
        $token->str,
        $token->len, 
        $token->u8len, 
        $token->pos, 
        $token->is_match, 
        $token->is_hot
     );
 }

DESCRIPTION

A Token represents one or more characters culled from a string by a Tokenizer.

METHODS

Most of Search::Tools::Token is written in C/XS so if you view the source of this class you will not see much code. Look at the source for Tools.xs and search-tools.c if you are interested in the internals, or look at Search::Tools::TokenPP.

str

The characters in the token. Stringifies to the str() value with overloading.

len

The byte length of str().

u8len

The character length of str(). For ASCII, len() == u8len(). For non-ASCII UTF-8, u8len() < len().

pos

The zero-based position in the original string.

is_match

Did the token match the re() in the Tokenizer.

is_hot

Did the token match the heat_seeker in the Tokenizer.

is_sentence_start

Returns true value if the Token starts with an UPPER case UTF8 character or other common sentence-starting character.

is_sentence_end

Returns true value if the Token matches common sentence-ending punctuation.

is_abbreviation

Returns true value if the Token looks like a common English abbreviation.

dump

Prints the internal XS attributes to stderr.

set_hot

Set the is_hot() value.

set_match

Set the is_match() value.
