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

NAME
       PPIx::Regexp::Structure - Represent a structure.

SYNOPSIS
	use PPIx::Regexp::Dumper;
	PPIx::Regexp::Dumper->new( 'qr{(foo)}' )->print();

INHERITANCE
       "PPIx::Regexp::Structure" is a PPIx::Regexp::Node.

       "PPIx::Regexp::Structure" is the parent of PPIx::Regexp::Structure::Assertion,
       PPIx::Regexp::Structure::BranchReset, PPIx::Regexp::Structure::Capture,
       PPIx::Regexp::Structure::CharClass, PPIx::Regexp::Structure::Code,
       PPIx::Regexp::Structure::Main, PPIx::Regexp::Structure::Modifier,
       PPIx::Regexp::Structure::Quantifier, PPIx::Regexp::Structure::Subexpression,
       PPIx::Regexp::Structure::Switch and PPIx::Regexp::Structure::Unknown.

DESCRIPTION
       This class represents a bracketed construction of some sort. The brackets considered part
       of the structure, but not inside it. So the "elements()" method returns the brackets if
       they are defined, but the "children()" method does not.

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.

   finish
	my $elem = $struct->finish();
	my @elem = $struct->finish();
	my $elem = $struct->finish( 0 );

       Returns the finishing structure element. This is included in the "elements" but not in the
       "children".

       The finishing element is actually an array, though it should never have more than one
       element. Calling "finish" in list context gets you all elements of the array. Calling it
       in scalar context gets you an element of the array, defaulting to element 0 if no argument
       is passed.

   start
	my $elem = $struct->start();
	my @elem = $struct->start();
	my $elem = $struct->start( 0 );

       Returns the starting structure element. This is included in the "elements" but not in the
       "children".

       The starting element is actually an array. The first element (element 0) is the actual
       starting delimiter. Subsequent elements, if any, are insignificant elements (comments or
       white space) absorbed into the start element for ease of parsing subsequent elements.

       Calling "start" in list context gets you all elements of the array.  Calling it in scalar
       context gets you an element of the array, defaulting to element 0 if no argument is
       passed.

   type
	my $elem = $struct->type();
	my @elem = $struct->type();
	my $elem = $struct->type( 0 );

       Returns the group type if any. This will be the leading PPIx::Regexp::Token::GroupType
       token if any. This is included in "elements" but not in "children".

       The type is actually an array. The first element (element 0) is the actual type
       determiner. Subsequent elements, if any, are insignificant elements (comments or white
       space) absorbed into the type element for consistency with the way the start element is
       handled.

       Calling "type" in list context gets you all elements of the array.  Calling it in scalar
       context gets you an element of the array, defaulting to element 0 if no argument is
       passed.
