preEvaluate() public method

Try to get a cached segment for the current path and return that with all uncached segments evaluated if it exists. Otherwise metadata for the cache lifetime is collected (if configured) for nested evaluations (to find the minimum maximumLifetime).
public preEvaluate ( array &$evaluateContext, object $tsObject ) : array
$evaluateContext array The current evaluation context
$tsObject object The current TypoScript object (for "this" in evaluations)
return array Cache hit state as boolean and value as mixed
