Class Pattern

Simple AbstractMatcher that uses a pattern to match rows.

A string pattern is compared directly against provided rows. By default the pattern is compared against the bells at the back of the change, e.g.:

const pat = new Pattern('5678');
pat.match('43125678'); // true (matches)
pat.match('43126578'); // false (doesn't match)
pat.isWildcardMatch;   // true
pat.matchCount;        // 1
pat.print('text');     // '1 5678'
Copy

It's also possible to check the bells at the front of the change:

const pat = new Pattern('8765', '8765 off the front', MatchType.Front);
pat.match('87654321'); // true
pat.isWildcardMatch;   // true
pat.print('text');     // '1 8765 off the front'
Copy

... or check an entire row:

const pat = new Pattern('13572468', 'Queens', MatchType.Row);
pat.match('13572468'); // true
pat.isWildcardMatch;   // false
pat.print('text');     // 'Queens'
Copy

If no pattern name is provided then the pattern itself will be used when printing results.
