Unordered

Introduction

This non-terminal tries to match all passed rules in no specific order.

Constructors

• Unordered(String... literals): Maps the passed strings to literals.
• Unordered(Rule... rules): Takes atleast 2 rules.
• Unordered(Function<Set<Token>, TokenSet> tokenFactory, String... literals): Like the string-constructor but takes an additional factory-method to produce a token instance.
• Unordered(Function<Set<Token>, TokenSet> tokenFactory, Rule... rules): Like the default-constructor but takes an additional factory-method to produce a token instance.

Examples

new Unordered("public", "static", "final");

Matches

"public static final"
"publicfinalstatic"
"final   publicstatic"

Fails

"public static"
"public public static final"
