=head1 NAME

Egg::Manager::View - View manager for Egg.

=head1 DESCRIPTION

It is a module to offer Egg the view function.

When the view_manager method of Egg is called, the handler class for the view
is returned.

=head1 CONFIGURATION

The configuration of the model is done to 'VIEW' by the ARRAY form.

  VIEW => [
    [ Mason => {
       ...........
       ....
       } ],
    [ HT => {
       ...........
       ....
       } ],
    ],

=head1 METHODS

Because this class is registered in @ISA of the project, the method can be used
directly from the object of the project.

  $project->view( ... );

=head2 init_view

When starting for the view, it initializes it.

=head2 setup_view

The setup for the view is done.

=head2 view ([LABEL_STRING])

The object of the specific view specified with LABEL_STRING is returned.

When LABEL_STRING is omitted, the object of the view of default is restored.

  my $mason= $e->view;
     or
  my $mason= $e->view('mason');

The setting of the first element set to the configuration becomes default.

It is L<Egg::View::Mason> in the view. With L<Egg::View::HT> However, Ts belongs.

=head2 is_view ([LABEL_STRING])

If the view corresponding to LABEL_STRING can be used, true is returned.

  unless ($e->is_model('mason')) {
     die q{ mason is not active. };
  }

=head1 HANDLER METHODS
