Class AbstractSchemeAbstract

Base for music matching schemes.

A scheme is a MatcherSet that is able to populate its child matches automatically based on the Stage.

Derived classes should implement createMatchers in order to set up an array of matchers for use when checking row strings.

class MyScheme extends AbstractScheme {
  public readonly name: string = 'My music scheme';

  protected createMatchers(rounds: string): AbstractMatcher[] {
    return [
      new Pattern(
        rounds.split('').reverse().join(''), // reverses rounds
        'Backrounds',
        MatchType.Row,
      ),
      // more patterns or pattern groups
    ];
  }
}
Copy

Once constructed, the base class manages:

• passing test row strings to all provided matchers
• aggregating match counts from matchers
• printing the music report
