    This method is used to cast the receiver object to be of type T0.

    This method is used to cast the receiver object to be of type T0.

    Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expressionList(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested typed.

  75. def eq(arg0: AnyRef): Boolean

    This method is used to test whether the argument (arg0) is a reference to the receiver object (this).

    This method is used to test whether the argument (arg0) is a reference to the receiver object (this).

    The eq method implements an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation] on non-null instances of AnyRef: * It is reflexive: for any non-null instance x of type AnyRef, x.eq(x) returns true. * It is symmetric: for any non-null instances x and y of type AnyRef, x.eq(y) returns true if and only if y.eq(x) returns true. * It is transitive: for any non-null instances x, y, and z of type AnyRef if x.eq(y) returns true and y.eq(z) returns true, then x.eq(z) returns true.

    Additionally, the eq method has three other 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).

Therefore the expression1.isInstanceOf[String] will return false, while the expression List(1).isInstanceOf[List[String]] will return true. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested typed.

  250. def withFilter(p: (Char) ⇒ Boolean): WithFilter

    Creates a non-strict filter of this mutable indexed sequence .

    Creates a non-strict filter of this mutable indexed sequence .

    Note: the difference between c filter p and c withFilter p is that the former creates a new collection, whereas the latter only restricts the domain of subsequent map, flatMap, foreach, and withFilter operations.

    p

    the predicate used to test elements .

    returns

    an object of class WithFilter, which supports map, flatMap, foreach, and withFilter operations. All these operations apply to those elements of this mutable indexed sequence which satisfy the predicate p.

  251. def zip[B](that: Iterable[B]): IndexedSeq[(Char, B)]

    [use case] Returns a mutable indexed sequence formed from this mutable indexed sequence and another iterable collection by combining corresponding elements in pairs .

    [use case]

    Returns a mutable indexed sequence formed from this mutable indexed sequence and another iterable collection by combining corresponding elements in pairs . If one of the two collections is longer than the other, its remaining elements are ignored.

    B

    the type of the second half of the returned pairs

    that

    The iterable providing the second half of each result pair

    returns

    a new mutable indexed sequence containing pairs consisting of corresponding elements of this mutable indexed sequence and that. The length of the returned collection is the minimum of the lengths of this mutable indexed sequence and that.

    Returns a mutable indexed sequence formed from this mutable indexed sequence and another iterable collection by combining corresponding elements in pairs . If one of the two collections is longer than the other, its remaining elements are ignored.

    A1

    the type of the first half of the returned pairs (this is always a supertype of the collection's element type A).

    B

    the type of the second half of the returned pairs

    That

    the class of the returned collection. Where possible, That is the same class as the current collection class Repr, but this depends on the element type (A1, B) being admissible for that class, which means that an implicit instance of type CanBuildFrom[Repr, (A1, B), That]. is found.

    that

    The iterable providing the second half of each result pair

    bf

    an implicit value of class CanBuildFrom which determines the result class That from the current representation type Repr and the new element type (A1, B).

    returns

    a new collection of type That containing pairs consisting of corresponding elements of this mutable indexed sequence and that. The length of the returned collection is the minimum of the lengths of this mutable indexed sequence and that.

    [use case]

    Returns a mutable indexed sequence formed from this mutable indexed sequence and another iterable collection by combining corresponding elements in pairs .

    the element to be used to fill up the result if this mutable indexed sequence is shorter than that.

    the element to be used to fill up the result if that is shorter than this mutable indexed sequence.

    a new mutable indexed sequence containing pairs consisting of corresponding elements of this mutable indexed sequence and that. The length of the returned collection is the maximum of the lengths of this mutable indexed sequence and that.
