@Deprecated public interface Collapsible extends Container.Hierarchical, Container.Ordered
Deprecated.UseTreeGrid.addExpandListener()
andTreeGrid.addCollapseListener()
.Container needed by large lazy loading hierarchies displayed e.g. in TreeTable.Container of this type gets notified when a subtree is opened/closed in a component displaying its content. This allows container to lazy load subtrees and release memory when a sub-tree is no longer displayed.
Methods from
Container.Ordered
(and fromContainer.Indexed
if implemented) are expected to work as in "preorder" of the currently visible hierarchy. This means for example that the return value of size method changes when subtree is collapsed/expanded. In other words items in collapsed sub trees should be "ignored" by container when the container is accessed with methods introduced inContainer.Ordered
orContainer.Indexed
. From the accessors point of view, items in collapsed subtrees don't exist.
