getFlavor

public RegexFlavor getFlavor()

getFeatureSet

public RegexFeatureSet getFeatureSet()

The set of features that the regex compilers will be able to support. This is used to detect unsupported regular expressions early, during their validation. This only applies to ECMAScript regular expressions. Other flavors implement their own validation logic.
