class Failure
[source: scala/util/parsing/combinator/Parsers.scala]
case class Failure(val override msg : java.lang.String, val override next : Reader)
extends NoSuccess with Product
The failure case of ParseResult: contains an error-message and the remaining input. Parsing will back-track when a failure occurs.
Parameters
msg - An error message string describing the failure.
next - The parser's unconsumed input at the point where the failure occurred.
Values and Variables inherited from NoSuccess
successful
Method Summary
def append [U](a : => ParseResult[U]) : ParseResult[U]
override def canEqual (arg0 : Any) : Boolean
A method that should be called from every well-designed equals method that is open to be overridden in a subclass. See Programming in Scala, Chapter 28 for discussion and design.
override def equals (arg0 : Any) : Boolean
The equality method defined in `AnyRef`.
override def hashCode : Int
Returns a hash code value for the object.
override def productArity : Int
return k for a product A(x_1,...,x_k)
override def productElement (arg0 : Int) : Any
for a product A(x_1,...,x_k), returns x_(n+1) for 0 <= n < k
override def productPrefix : java.lang.String
By default the empty string. Implementations may override this method in order to prepend a string prefix to the result of the toString methods.
override def toString : java.lang.String
The toString method of a Failure yields an error message

Method Details
override def toString : java.lang.String
The toString method of a Failure yields an error message
def append[U](a : => ParseResult[U]) : ParseResult[U]
override def hashCode : Int
Returns a hash code value for the object.

The default hashing algorithm is platform dependent. Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

Returns
the hash code value for the object.

override def equals(arg0 : Any) : Boolean
The equality method defined in `AnyRef`.
override def productPrefix : java.lang.String
By default the empty string. Implementations may override this method in order to prepend a string prefix to the result of the toString methods.
Overrides
Product.productPrefix
override def productArity : Int
return k for a product A(x_1,...,x_k)
Overrides
Product.productArity
override def productElement(arg0 : Int) : Any
for a product A(x_1,...,x_k), returns x_(n+1) for 0 <= n < k
Parameters
n - the index of the element to return
Throws
IndexOutOfBoundsException -
Returns
The element n elements after the first element
Overrides
Product.productElement
override def canEqual(arg0 : Any) : Boolean
A method that should be called from every well-designed equals method that is open to be overridden in a subclass. See Programming in Scala, Chapter 28 for discussion and design.
