BitPatternGroup<T, V extends BitPattern<T>> class

Allows matching integer values against a collection of BitPatterns.

A BitPatternGroup is a collection of BitPatterns which may match a given set of bits (represented as an int). Unlike a BitPattern, a BitPatternGroup matches a BitPattern, which in turn can then capture bits:

void example(List<BitPattern<List<int>> patterns, int value) {
  final group = BitPatternGroup.from(patterns);
  final match = group.match(value);

  // Prints out the captured bits.
  print(match.capture(value));
}

This utility is useful for creating decoders (for example, for emulators).
