PPIx::QuoteLike::Token(3)

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.
