notifyQueryEvaluated	back to summary
public void notifyQueryEvaluated(MediaQuery query, boolean currentValue) Notifies the media query context that a query has been evaluated and provides its current value. The context can then re-evaluate the query at its own discretion and compare the evaluated value with the stored value to determine if it is necessary to re-apply CSS. This is an optimization to minimize CSS invalidation. For example, range-based queries like "width" and "height" can change very often when the scene is resized (but the evaluated value doesn't change often in a query like "width < 500"). If not for this optimization, we would have to speculatively re-apply CSS on every resize just to catch the case when a range-based query changes its value. Parameters query:MediaQuery the query currentValue:boolean the query value
