+=head1 NAME
+
+Reaction::UI::ViewPort::Collection
+
+=head1 DESCRIPTION
+
+Creates, from an InterfaceModel::Collection, a list of viewports representing
+each member of the collection.
+
+=head1 ATTRIBUTES
+
+=head2 collection
+
+Required read-only L<InterfaceModel::Collection|Reaction::InterfaceModel::Collection>
+This is the original collection.
+
+=head2 current_collection
+
+Read-only, lazy-building
+L<InterfaceModel::Collection|Reaction::InterfaceModel::Collection>
+This is the collection that will be used to create C<members> and should be
+altered to reflect any ordering, paging, etc. By default this is the
+same thing as C<collection>.
+
+=head2 member_args
+
+A read-write HASH ref of additional parameters to pass to the C<member_class>
+constructor as items are instantiated.
+
+=head2 member_class
+
+The class to use when instantiating items to represent the member items.
+
+See: L<Object|Reaction::UI::ViewPort::Object>,
+L<Member|Reaction::UI::ViewPort::Collection::Grid::Member>.
+
+=head1 INTERNAL METHODS
+
+These methods, although stable, are subject to change without notice.
+Extend at your own risk, APIs may change in the future.
+
+=head2 BUILD
+
+Intercept a parameter with the key C<Member> amd store it in C<member_args>
+
+=head2 model
+
+Returns the C<current_collection>
+
+=head2 _build_members
+
+Build individual viewports for each member of the collection,
+
+=head2 _build_member_args
+
+Defaults to an empty HASH ref.
+
+=head2 _build_member_class
+
+Defaults to L<Reaction::UI::ViewPort::Object>
+

+
+See L<Reaction::Class> for authors.
