Class ClientPropertyStore

java.lang.Object

com.vaadin.swingbridge.surrogates.internal.ClientPropertyStore

public final class ClientPropertyStore
extends Object

Per-component client-property map backing JComponentMixin.putClientProperty / getClientProperty. Swing's contract: writing null removes the mapping, and the mixin fires PropertyChangeEvent named after key.toString() when the value actually changes. Storage is a plain HashMap — lookups aren't on any hot path.
