Class DelegatingThemeSource

All Implemented Interfaces:
HierarchicalThemeSource, ThemeSource

@Deprecated(since="6.0") public class DelegatingThemeSource extends Object implements HierarchicalThemeSource
as of 6.0 in favor of using CSS, without direct replacement
Empty ThemeSource that delegates all calls to the parent ThemeSource. If no parent is available, it simply won't resolve any theme.

Used as placeholder by UiApplicationContextUtils, if a context doesn't define its own ThemeSource. Not intended for direct use in applications.
