Package-level declarations

What a modifier element puts back when its declaration leaves, declared through SwingModifier.NodeElement.restores.

An ordered, immutable collection of Elements applied to a Swing component - the Swing analogue of androidx.compose.ui.Modifier. Most are a NodeElement, which carries the node that writes onto the component; the rest declare something the node holder reads itself, such as where the component is attached in its parent.

The diff state for one node's modifier: the elements applied last, and the buffers the modifier being applied is partitioned into.

Ties this modifier's application to keys. While they stand the modifier is diffed as usual; a key that does not compare equal to the one applied last takes the whole modifier apart and applies it again from scratch.

Declares one Swing property on the component. The property is read as the declaration arrives and written back when the declaration leaves, so a widget that outlives it carries what it did before. Fold the element in only while a value is declared:

Declares one Swing property on the component, naming the component type as a value.
