    • chain

      public static <A, B, R> Parser<R> chain(Parser<A> aParser, Parser<B> bParser, Combinators.BiCombinator<A,B,R> combinator)
      Take two parsers and return a new one, which will pass iff both parsers succeed when running one after the other.
      类型参数:
      A - Return type of the first parser.
      B - Return type of the second parser.
      R - The new return type.
      参数:
      aParser - The parser that should run first.
      bParser - The second parser.
      combinator - A function to combine the result of both parsers into one object.
      返回:
      A new parser which succeeds only when both input parsers succeed.

      Same as chain(Parser, Parser, BiCombinator), just with 3 parsers.

      Same as chain(Parser, Parser, BiCombinator), just with 4 parsers.

      public static <A, B, C, D, E, R> Parser<R> chain(Parser<A> aParser, Parser<B> bParser, Parser<C> cParser, Parser<D> dParser, Parser<E> eParser, Combinators.PentaCombinator<A,B,C,D,E,R> combinator)
      Same as chain(Parser, Parser, BiCombinator), just with 5 parsers.

    • repeat

      public static <T> Parser<List<T>> repeat(Parser<T> parser)
      Construct a new parser, that will try to run the given one repeatedly and return a list.

      Note: This parser always succeeds, because if it won't match anything, it will still return an empty list.

      类型参数:
      T - Return type of the input parser.
      参数:
      parser - The parser to repeatedly run.
      返回:
      The new parser.

    • optional

      public static <T> Parser<Optional<T>> optional(Parser<T> parser)
      Return a parser which succeeds even in cases when it can't parse anything.
      类型参数:
      T - The return type of the parser.
      参数:
      parser - A parser to wrap with an optional check.
      返回:
      A new parser that doesn't fail when no input is successfully parsed.

    • oneOf

      @SafeVarargs public static <T> Parser<T> oneOf(Parser<? extends T>... parsers)
      Given a list of parsers of the same type, return a result of the first one that succeeds. Or null if none succeed.
      类型参数:
      T - The return type of all the parsers involved.
      参数:
      parsers - The input parsers to all try.
      返回:
      A new parser that tries all the given parsers.
