SetProxy

trait SetProxy [A] extends Set[A] with SetProxyLike[A, Set[A]]

This is a simple wrapper class for scala.collection.mutable.Set. It is most useful for assembling customized set abstractions dynamically using object composition and forwarding.

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

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.

    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.

    returns

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

    This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.

    This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.

    The default implementations of this method is an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation]: * It is reflexive: for any instance x of type Any, x.equals(x) should return true. * It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true. * It is transitive: for any instances x, y, and z of type AnyRef if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

    If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is often necessary to override hashCode to ensure that objects that are "equal" (o1.equals(o2) returns true) hash to the same scala.Int (o1.hashCode.equals(o2.hashCode)).

    returns

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

    thatElem

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

    returns

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

    [use case] Zips this mutable set with its indices.

    [use case]

    Zips this mutable set with its indices.

    returns

    A new mutable set containing pairs consisting of all elements of this mutable set paired with their index. Indices start at 0. @example List("a", "b", "c").zipWithIndex = List(("a", 0), ("b", 1), ("c", 2))

    Zips this mutable set with its indices.

    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).

    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, Int) being admissible for that class, which means that an implicit instance of type CanBuildFrom[Repr, (A1, Int), That]. is found.

    returns

    A new collection of type That containing pairs consisting of all elements of this mutable set paired with their index. Indices start at 0.

    Computes the union between this set and another set.

    Computes the union between this set and another set.

    Note: Same as union.

    that

    the set to form the union with.

    returns

    a new set consisting of all elements that are in this set or in the given set that.
