PPIx::Regexp::Element(3)       User Contributed Perl Documentation	 PPIx::Regexp::Element(3)

NAME
       PPIx::Regexp::Element - Base of the PPIx::Regexp hierarchy.

SYNOPSIS
       No user-serviceable parts inside.

INHERITANCE
       "PPIx::Regexp::Element" is not descended from any other class.

       "PPIx::Regexp::Element" is the parent of PPIx::Regexp::Node and PPIx::Regexp::Token.

DESCRIPTION
       This class is the base of the PPIx::Regexp object hierarchy. It provides the same kind of
       navigational functionality that is provided by PPI::Element.

METHODS
       This class provides the following public methods. Methods not documented here are private,
       and unsupported in the sense that the author reserves the right to change or remove them
       without notice.

   ancestor_of
       This method returns true if the object is an ancestor of the argument, and false
       otherwise. By the definition of this method, $self is its own ancestor.

   can_be_quantified
	$token->can_be_quantified()
	    and print "This element can be quantified.\n";

       This method returns true if the element can be quantified.

   class
       This method returns the class name of the element. It is the same as "ref $self".

   comment
       This method returns true if the element is a comment and false otherwise.

   content
       This method returns the content of the element.

   descendant_of
       This method returns true if the object is a descendant of the argument, and false
       otherwise. By the definition of this method, $self is its own descendant.

   is_quantifier
	$token->is_quantifier()
	    and print "This element is a quantifier.\n";

       This method returns true if the element is a quantifier. You can not tell this from the
       element's class, because a right curly bracket may represent a quantifier for the purposes
       of figuring out whether a greediness token is possible.

   next_sibling
       This method returns the element's next sibling, or nothing if there is none.

   parent
       This method returns the parent of the element, or undef 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
       This method returns the element's previous sibling, or nothing if there is none.

   significant
       This method returns true if the element is significant and false otherwise.

   snext_sibling
       This method returns the element's next significant sibling, or nothing if there is none.

   sprevious_sibling
       This method returns the element's previous significant sibling, or nothing if there is
       none.

   tokens
       This method returns all tokens contained in the element.

   top
       This method returns the top of the hierarchy.

   unescaped_content
       This method returns the content of the element, unescaped.

   whitespace
       This method returns true if the element is whitespace and false otherwise.

   nav
       This method returns navigation information from the top of the hierarchy to this node. The
       return is a list of names of methods and references to their argument lists. The idea is
       that given $elem which is somewhere under $top,

	my @nav = $elem->nav();
	my $obj = $top;
	while ( @nav ) {
	    my $method = shift @nav;
	    my $args = shift @nav;
	    $obj = $obj->$method( @{ $args } ) or die;
	}
	# At this point, $obj should contain the same object
	# as $elem.

       Support is by the author. Please file bug reports at <http://rt.cpan.org>, or in
       electronic mail to the author.
