LaTeX::TikZ::Set::Path - A role for set objects that can be part of a path.
=head1 VERSION
Version 0.03

our $VERSION = '0.03';
=head1 DESCRIPTION
Paths are all the elements against which we can call the C<path> method.
=cut
use Mouse::Role;
=head1 RELATIONSHIPS
This role consumes the L<LaTeX::TikZ::Set> role, and as such implements the L</draw> method.
=cut
with 'LaTeX::TikZ::Set';
=head1 METHODS
These methods are required by the interface :
=over 4
=item *
C<path $formatter, $context>
Returns the TikZ code that builds a path out of the current set object as a string formatted by the L<LaTeX::TikZ::Formatter> object C<$formatter>.
The current evaluation context is passed as the L<LaTeX::TikZ::Context> object C<$context>.
=item *
C<begin>
Returns a L<LaTeX::TikZ::Point> object pointing to the beginning of the path, or C<undef> if this path has no beginning.
=item *
C<end>
A L<LaTeX::TikZ::Point> object pointing to the end of the path, or C<undef> if this path has no end.
