ParseResult

Related Doc: package Parsers

sealed abstract class ParseResult[+T] extends AnyRef

A base class for parser results. A result is either successful or not (failure may be fatal, i.e., an Error, or not, i.e., a Failure). On success, provides a result of type T which consists of some result (and the rest of the input).

Abstract Value Members

  1. abstract def append[U >: T](a: ⇒ ParseResult[U]): ParseResult[U]

  2. abstract def filterWithError(p: (T) ⇒ Boolean, error: (T) ⇒ String, position: Input): ParseResult[T]

  3. abstract def flatMapWithNext[U](f: (T) ⇒ (Input) ⇒ ParseResult[U]): ParseResult[U]

  4. abstract def get: T

    Returns the embedded result.

  5. abstract def map[U](f: (T) ⇒ U): ParseResult[U]

    Functional composition of ParseResults.

    Functional composition of ParseResults.

    f

    the function to be lifted over this result

    returns

    f applied to the result of this ParseResult, packaged up as a new ParseResult

  6. abstract def mapPartial[U](f: PartialFunction[T, U], error: (T) ⇒ String): ParseResult[U]

    Partial functional composition of ParseResults.

    Partial functional composition of ParseResults.

    f

    the partial function to be lifted over this result

    error

    a function that takes the same argument as f and produces an error message to explain why f wasn't applicable (it is called when this is the case)

    returns

    if f f is defined at the result in this ParseResult, f applied to the result of this ParseResult, packaged up as a new ParseResult. If f is not defined, Failure.
