=head1 NAME
Mojolicious::Routes::Route - Route
=head1 SYNOPSIS
use Mojolicious::Routes::Route;
my $r = Mojolicious::Routes::Route->new;
=head1 DESCRIPTION
L<Mojolicious::Routes::Route> is the route container used by
L<Mojolicious::Routes>.
=head1 ATTRIBUTES
L<Mojolicious::Routes::Route> implements the following attributes.
=head2 children
my $children = $r->children;
$r = $r->children([Mojolicious::Routes::Route->new]);
The children of this route, used for nesting routes.
=head2 inline
my $bool = $r->inline;
$r = $r->inline($bool);
Allow L</"under"> semantics for this route.
=head2 parent
my $parent = $r->parent;
$r = $r->parent(Mojolicious::Routes::Route->new);
The parent of this route, usually a L<Mojolicious::Routes::Route> object.
=head2 partial
my $bool = $r->partial;
$r = $r->partial($bool);
Route has no specific end, remaining characters will be captured in C<path>.
=head2 pattern
my $pattern = $r->pattern;
$r = $r->pattern(Mojolicious::Routes::Pattern->new);
Pattern for this route, defaults to a L<Mojolicious::Routes::Pattern> object.
=head1 METHODS
L<Mojolicious::Routes::Route> inherits all methods from L<Mojo::Base> and
implements the following new ones.
=head2 add_child
$r = $r->add_child(Mojolicious::Routes::Route->new);
Add a new child to this route, it will be automatically removed from its
current parent if necessary.
# Reattach route
$r->add_child($r->find('foo'));
=head2 any
my $route = $r->any('/:foo');
my $route = $r->any('/:foo' => sub {...});
my $route = $r->any('/:foo' => {foo => 'bar'} => sub {...});
my $route = $r->any('/:foo' => [foo => qr/\w+/] => sub {...});
my $route = $r->any([qw(GET POST)] => '/:foo' => sub {...});
my $route = $r->any([qw(GET POST)] => '/:foo' => [foo => qr/\w+/]);
Generate L<Mojolicious::Routes::Route> object matching any of the listed HTTP
request methods or all. See also the L<Mojolicious::Lite> tutorial for many
more argument variations.
$r->any('/user')->to('user#whatever');
=head2 bridge
my $route = $r->bridge;
my $route = $r->bridge('/:action');
my $route = $r->bridge('/:action', action => qr/\w+/);
my $route = $r->bridge(format => 0);
Low-level generator for nested routes with their own intermediate destination,
returns a L<Mojolicious::Routes::Route> object.

$auth->get('/show')->to('#show');
$auth->post('/create')->to('#create');
=head2 delete
my $route = $r->delete('/:foo');
my $route = $r->delete('/:foo' => sub {...});
my $route = $r->delete('/:foo' => {foo => 'bar'} => sub {...});
my $route = $r->delete('/:foo' => [foo => qr/\w+/] => sub {...});
Generate L<Mojolicious::Routes::Route> object matching only C<DELETE>
requests. See also the L<Mojolicious::Lite> tutorial for many more argument
variations.
$r->delete('/user')->to('user#remove');
=head2 detour

Set default parameters for this route and allow partial matching to simplify
application embedding, takes the same arguments as L</"to">.

generated ones.

=head2 has_custom_name
my $bool = $r->has_custom_name;
Check if this route has a custom name.
=head2 has_websocket
my $bool = $r->has_websocket;
Check if this route has a WebSocket ancestor and cache the result for future
checks.
=head2 is_endpoint
my $bool = $r->is_endpoint;
Check if this route qualifies as an endpoint.
=head2 is_websocket
my $bool = $r->is_websocket;
Check if this route is a WebSocket.
=head2 name

$r = $r->name('foo');
The name of this route, defaults to an automatically generated name based on
the route pattern. Note that the name C<current> is reserved for referring to
the current route.
$r->get('/user')->to('user#show')->name('show_user');
=head2 new
my $r = Mojolicious::Routes::Route->new;
my $r = Mojolicious::Routes::Route->new('/:controller/:action');

if necessary.

requests. See also the L<Mojolicious::Lite> tutorial for many more argument
variations.

$r = $r->over(foo => 1, bar => {baz => 'yada'});
$r = $r->over([foo => 1, bar => {baz => 'yada'}]);
Activate conditions for this route. Note that this automatically disables the
routing cache, since conditions are too complex for caching.
