findRecomposer

The Recomposer driving this component's composed content, or null where nothing this library mounted drives it.

The search starts at this component and walks up its Swing ancestors as far as the window holding it, so a container carrying a content composition answers for that composition, and anything nested inside one answers for the scope around it. A Window with a root pane answers for the content standing in it, whether that content composes on a recomposer the window owns or under a context a caller named - which is what a window declared inside application { } composes under. A window owned by another answers for itself rather than for its owner. It reads what is already there and starts nothing.

null covers a component nothing above it answers for: one no composed content stands in, one whose content composes under a recomposer that is not this library's, and a window with no root pane, which shares no recomposer to answer with - its content still answers, asked where it stands.

Must be called on the Event Dispatch Thread.
