Method Details

navGrouper

NavGrouper navGrouper()

The current nav grouping strategy; call NavGrouper.nodeFor(MenuEntry) for each entry from com.vaadin.flow.server.menu.MenuConfiguration#getMenuEntries().

currentPath

String currentPath()

The path of the currently active navigation, with any leading / stripped.

slots

NavSlots slots()

The full set of named locations available to render into.

navPathMatcher

BiPredicate<String,String> navPathMatcher()

The configured AppNavLayout.setNavPathMatcher(BiPredicate) predicate for active-item matching (default String::equals). A NavRenderer that highlights an active item by comparing paths itself — rather than delegating to something that already respects it, like Vaadin's own router matching — should test against this rather than hardcoding its own comparison, or setNavPathMatcher silently won't affect it.
