A method that should be called from every well-designed equals method that is open to be overridden in a subclass
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.
The equality method defined in AnyRef

.
Returns the embedded result
Returns a hash code value for the object
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.

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)
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'.
return k for a product A(x_1,
return k for a product A(x_1,...,x_k)
for a product A(x_1,
for a product A(x_1,...,x_k)
, returns x_(n+1)
for 0 <= n < k
An iterator that returns all fields of this product
By default the empty 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.
The toString method of a Failure yields an error message @return a string representation of the object
The toString method of a Failure yields an error message @return a string representation of the object.

The failure case of ParseResult: contains an error-message and the remaining input. Parsing will back-track when a failure occurs.
An error message string describing the failure.
The parser's unconsumed input at the point where the failure occurred.
