ParseResult

sealed abstract class ParseResult[+T]
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).

Methods

def map[U](f: T => U): ParseResult[U]
Functional composition of ParseResults.
Value Params
f
the function to be lifted over this result
Returns
f applied to the result of this ParseResult, packaged up as a new ParseResult
def mapPartial[U](f: PartialFunction[T, U], error: T => String): ParseResult[U]
Partial functional composition of ParseResults.
Value Params
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)
f
the partial function to be lifted over this result
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.
def filterWithError(p: T => Boolean, error: T => String, position: Input): ParseResult[T]
def append[U >: T](a: => ParseResult[U]): ParseResult[U]
def isEmpty: Boolean
def get: T
Returns the embedded result.
def getOrElse[B >: T](default: => B): B
