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.
