ImmutableMapAdaptor

class ImmutableMapAdaptor [A, B] extends Map[A, B]

This class can be used as an adaptor to create mutable maps from immutable map implementations. Only method empty has to be redefined if the immutable map on which this mutable map is originally based is not empty. empty is supposed to return the representation of an empty map.

    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.

  52. 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).

    arg0

    the object to compare against this object for reference equality.

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

  172. def view (from: Int, until: Int) : IterableView[(A, B), Map[A, B]]

    Creates a non-strict view of a slice of this shrinkable collection.

    Creates a non-strict view of a slice of this shrinkable collection.

    Note: the difference between view and slice is that view produces a view of the current shrinkable collection, whereas slice produces a new shrinkable collection.

    Note: view(from, to) is equivalent to view.slice(from, to)

    Note: might return different results for different runs, unless the underlying collection type is ordered.

    from

    the index of the first element of the view

    until

    the index of the element following the view

    returns

    a non-strict view of a slice of this shrinkable collection, starting at index from and extending up to (but not including) index until.

    Creates a non-strict filter of this shrinkable collection.

    Creates a non-strict filter of this shrinkable collection.

    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.

    Note: might return different results for different runs, unless the underlying collection type is ordered.

    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 shrinkable collection which satisfy the predicate p.

    [use case]

    Returns a shrinkable collection formed from this shrinkable collection 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 shrinkable collection containing pairs consisting of corresponding elements of this shrinkable collection and that. The length of the returned collection is the minimum of the lengths of this shrinkable collection and that.

    Returns a shrinkable collection formed from this shrinkable collection 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.

    Note: might return different results for different runs, unless the underlying collection type is ordered.

    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).

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

    [use case]

    Returns a shrinkable collection formed from this shrinkable collection and another iterable collection by combining corresponding elements in pairs. If one of the two collections is shorter than the other, placeholder elements are used to extend the shorter collection to the length of the longer.

    that

    The iterable providing the second half of each result pair

    thisElem

    the element to be used to fill up the result if this shrinkable collection is shorter than that.

    thatElem

    the element to be used to fill up the result if that is shorter than this shrinkable collection.

    returns

    a new shrinkable collection containing pairs consisting of corresponding elements of this shrinkable collection and that. The length of the returned collection is the maximum of the lengths of this shrinkable collection and that. If this shrinkable collection is shorter than that, thisElem values are used to pad the result. If that is shorter than this shrinkable collection, thatElem values are used to pad the result.
