Method Detail

makeFeatureSet

public void makeFeatureSet(FeatureConfig<T> configAdaptor)

The config adaptor provides a set of feature names it can configure, and provides the API to configure them. Once we get the list of features we get them all rather then fetching them in a lazy fashion. The rationale is to take any performance hit at startup.

Parameters:

configAdaptor -

public boolean isEnabled(java.lang.String featureName,
                         T t)
