  18. final def asInstanceOf[T0]: T0

    Cast the receiver object to be of type T0.

    Cast the receiver object to be of type T0.

Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not.

  37. final def eq(arg0: AnyRef): Boolean

    Tests whether the argument (arg0) is a reference to the receiver object (this).

    Tests whether the argument (arg0) is a reference to the receiver object (this).

    The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:

    • It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
    • For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
    • null.eq(null) returns true.

    When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

    returns

    true if the argument is a reference to the receiver object; false otherwise.

  75. def rep1[T](first: ⇒ Parser[T], p0: ⇒ Parser[T]): Parser[List[T]]

    A parser generator for non-empty repetitions.

    A parser generator for non-empty repetitions.

    rep1(f, p) first uses f (which must succeed) and then repeatedly uses p to parse the input until p fails (the result is a List of the consecutive results of f and p)

    first

    a Parser that parses the first piece of input

    p0

    a Parser that is to be applied successively to the rest of the input (if any) -- evaluated at most once, and only when necessary

    returns

    A parser that returns a list of results produced by first applying f and then repeatedly p to the input (it only succeeds if f matches).

    Migration

    (Changed in version 2.9.0) The p0 call-by-name arguments is evaluated at most once per constructed Parser object, instead of on every need that arises during parsing.

    A parser generator for non-empty repetitions.

    rep1(p) repeatedly uses p to parse the input until p fails -- p must succeed at least once (the result is a List of the consecutive results of p)

    p

    A parser generator for non-empty repetitions.

    A parser generator for non-empty repetitions.

    rep1sep(p, q) repeatedly applies p interleaved with q to parse the input, until p fails. The parser p must succeed at least once.

    p

    a Parser that is to be applied successively to the input

    q

    a Parser that parses the elements that separate the elements parsed by p (interleaved with q)

    returns

    A parser that returns a list of results produced by repeatedly applying p to the input (and that only succeeds if p matches at least once). The results of p are collected in a list. The results of q are discarded.

    A parser generator for a specified number of repetitions.

    repN(n, p) uses p exactly n time to parse the input (the result is a List of the n consecutive results of p).

    num

    the exact number of times p must succeed

    p

    a Parser that is to be applied successively to the input

    A parser generator for interleaved repetitions.

    A parser generator for interleaved repetitions.

    repsep(p, q) repeatedly uses p interleaved with q to parse the input, until p fails. (The result is a List of the results of p.)

    Example: repsep(term, ",") parses a comma-separated list of term's, yielding a list of these terms.

    p

    a Parser that is to be applied successively to the input

    q

    a Parser that parses the elements that separate the elements parsed by p

    returns

    A parser that returns a list of results produced by repeatedly applying p (interleaved with q) to the input. The results of p are collected in a list. The results of q are discarded.
