Method Details

evaluateFeatures

public <T> Map<String,FeatureResult<T>> evaluateFeatures(List<String> featureKeys,
 EvaluationContext context,
 Class<T> valueTypeClass)

Evaluates a batch of features against a single, shared EvaluationContext. The context (and the GlobalContext it references) is reused for every key instead of being rebuilt per feature, and the per-evaluation stack is reset between features so evaluation state does not leak. A feature whose evaluation throws is recorded as FeatureResultSource.UNKNOWN_FEATURE rather than aborting the batch.

Each distinct key is evaluated exactly once (so feature-usage callbacks fire once per key) and the returned map preserves the order of featureKeys.
