NAME

       PPIx::QuoteLike::Token - Represent any token.

SYNOPSIS

       This is an abstract class, and should not be instantiated by the user.

DESCRIPTION

       This Perl module represents the base of the token hierarchy.

INHERITANCE

       "PPIx::QuoteLike::Token" is not descended from any other class.

       "PPIx::QuoteLike::Token" is the parent of PPIx::QuoteLike::Token::Control,
       PPIx::QuoteLike::Token::Interpolation, PPIx::QuoteLike::Token::String,
       PPIx::QuoteLike::Token::Structure, PPIx::QuoteLike::Token::Unknown and
       PPIx::QuoteLike::Token::Whitespace.

METHODS

       This class supports the following public methods:

   content
        say $token->content();

       This method returns the text that makes up the token.

   error
        say $token->error();

       This method returns the error text. This will be "undef" unless the token actually
       represents an error.

   parent
        my $parent = $token->parent();

       This method returns the token's parent, which will be the PPIx::QuoteLike object that
       contains it.

   next_sibling
        my $next = $token->next_sibling();

       This method returns the token after the invocant, or nothing if there is none.

   perl_version_introduced
       This method returns the version of Perl in which the element was introduced. This will be
       at least 5.000. Before 5.006 I am relying on the perldelta, perlre, and perlop
       documentation, since I have been unable to build earlier Perls. Since I have found no
       documentation before 5.003, I assume that anything found in 5.003 is also in 5.000.

       Since this all depends on my ability to read and understand masses of documentation, the
       results of this method should be viewed with caution, if not downright skepticism.

       There are also cases which are ambiguous in various ways. For those see "RESTRICTIONS" in
       PPIx::Regexp, and especially "Changes in Syntax" in PPIx::Regexp.

   perl_version_removed
       This method returns the version of Perl in which the element was removed. If the element
       is still valid the return is "undef".

       All the caveats to perl_version_introduced() apply here also, though perhaps less severely
       since although many features have been introduced since 5.0, few have been removed.

   previous_sibling
        my $prev = $token->previous_sibling();

       This method returns the token before the invocant, or nothing if there is none.

   significant
        $token->significant()
            and say 'significant';

       This Boolean method returns a true value if the token is significant, and a false one
       otherwise.

   snext_sibling
        my $next = $token->snext_sibling();

       This method returns the significant token after the invocant, or nothing if there is none.

   sprevious_sibling
        my $prev = $token->sprevious_sibling();

       This method returns the significant token before the invocant, or nothing if there is
       none.
