Examples of org.auraframework.css.ThemeList

org.auraframework.css.ThemeList
Represents a list of {@link ThemeDef}s.
This gives special attention to themes utilizing {@link ThemeDescriptorProvider} by storing the result of{@link ThemeDef#getConcreteDescriptor()} wherever possible. This helps to minimize the number of calls to{@link ThemeDescriptorProvider#provide()} to just once per theme (within this instance).
Likewise, special attention is also given to themes utilizing {@link ThemeMapProvider}, taking care to minimize the number of calls to {@link ThemeMapProvider#provide()} to just once per theme (within this instance).
Instances of this type are iterable over the contained themes (can be used in enhanced for-loop) in specified order. Take note that for CSS evaluation/parsing, {@link #orderedForEvaluation()} should be used instead.
While no methods exist on this interface for mutability, be aware that implementations might be mutable. Methods on this interface that return collections should return immutable and/or defensive copies of the current state, however.

        DefDescriptor<?> appDesc = context.getLoadingApplicationDescriptor();
        final String uid = context.getUid(appDesc);
        keyBuilder.append(uid);


        // themes uid (themes specified directly to the context (not on the app) need to be considered)
        final ThemeList themeList = context.getThemeList();
        Optional<String> themesUid = themeList.getThemeDescriptorsUid();
        if (themesUid.isPresent()) {
          keyBuilder.append(":").append(themesUid.get());
        }


        // 2) TODONM: If a theme uses a map-provider it will affect the css key too. Current idea is to cache a "pre-themed"
        // version of the CSS (but still ordered and concatenated). Until this is addressed map-providers shouldn't be
        // used. Another idea is to defer cache to fileforce, etc... once a map-provider is involved. (actually right now
        // we are skipping the cache, but when we stop doing that then this needs to be addressed


        final String key = keyBuilder.toString();
        context.setPreloading(true);


        String cached = context.getDefRegistry().getCachedString(uid, appDesc, key);
        boolean skipCache = themeList.hasDynamicVars(); // for now, skip caching css with dynamic var overrides


        if (cached == null || skipCache) {
            Collection<StyleDef> orderedStyleDefs = filterAndLoad(StyleDef.class, dependencies, null);
            StringBuffer sb = new StringBuffer();
            Aura.getSerializationService().writeCollection(orderedStyleDefs, StyleDef.class, sb, "CSS");
