class ParseResult
[source: scala/util/parsing/combinatorold/Parsers.scala]
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.
Direct Known Subclasses:
Parsers.Success, Parsers.NoSuccess
Value Summary
abstract val next : Reader
abstract val successful : Boolean
Method Summary
abstract def get : T
Returns the embedded result
def getOrElse [B >: T](default : => B) : B
def isEmpty : Boolean
abstract def map [U](f : (T) => U) : ParseResult[U]
Functional composition of ParseResults
abstract def mapPartial [U](f : PartialFunction[T, U], error : (T) => java.lang.String) : ParseResult[U]
Partial functional composition of ParseResults

Method Details
abstract def map[U](f : (T) => U) : ParseResult[U]
Functional composition of ParseResults
Parameters
`f' - the function to be lifted over this result
Returns
`f' applied to the result of this `ParseResult', packaged up as a new `ParseResult'
abstract def mapPartial[U](f : PartialFunction[T, U], error : (T) => java.lang.String) : ParseResult[U]
Partial functional composition of ParseResults
Parameters
`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'.
def isEmpty : Boolean
abstract def get : T
Returns the embedded result
