SortedSet

Creates a new set with an additional element, unless the element is already present.

Creates a new set with a given element removed from this set.

Tests if some element is contained in this set.

Creates a ranged projection of this collection. Any mutations in the ranged projection will update this collection and vice versa.

Note: keys are not garuanteed to be consistent between this collection and the projection. This is the case for buffers where indexing is relative to the projection.

Test two objects for inequality.

Equivalent to x.hashCode except for boxed numeric types and null. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For null returns a hashcode where null.hashCode throws a NullPointerException.

Computes the intersection between this set and another set.

Note: Same as intersect.

The difference of this set and another set.

Note: Same as diff.

Creates a new immutable sorted set with additional elements.

This method takes two or more elements to be added. Another overloaded variant of this method handles the case where a single element is added.

Creates a new immutable sorted set by adding all elements contained in another collection to this immutable sorted set.

As with ++, returns a new collection containing the elements from the left operand followed by the elements from the right operand.

It differs from ++ in that the right operand determines the type of the resulting collection rather than the left one. Mnemonic: the COLon is on the side of the new COLlection type.

Example:

    scala> val x = List(1)
    x: List[Int] = List(1)

    scala> val y = LinkedList(2)
    y: scala.collection.mutable.LinkedList[Int] = LinkedList(2)

    scala> val z = x ++: y
    z: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2)

This overload exists because: for the implementation of ++: we should reuse that of ++ because many collections override it with more efficient versions.

Since TraversableOnce has no ++ method, we have to implement that directly, but Traversable and down can use the overload.

Creates a new immutable sorted set from this immutable sorted set with some elements removed.

This method takes two or more elements to be removed. Another overloaded variant of this method handles the case where a single element is removed.

Creates a new immutable sorted set from this immutable sorted set by removing all elements of another collection.

Applies a binary operator to a start value and all elements of this immutable sorted set, going left to right.

Note: /: is alternate syntax for foldLeft; z /: xs is the same as xs foldLeft z.

Examples:

Note that the folding function used to compute b is equivalent to that used to compute c.

     scala> val a = LinkedList(1,2,3,4)
     a: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2, 3, 4)

     scala> val b = (5 /: a)(_+_)
     b: Int = 15

     scala> val c = (5 /: a)((x,y) => x + y)
     c: Int = 15

Note: might return different results for different runs, unless the underlying collection type is ordered. or the operator is associative and commutative.

A syntactic sugar for out of order folding. See fold.

Example:

     scala> val a = LinkedList(1,2,3,4)
     a: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2, 3, 4)

     scala> val b = (a /:\ 5)(_+_)
     b: Int = 15

Applies a binary operator to all elements of this immutable sorted set and a start value, going right to left.

Note: :\ is alternate syntax for foldRight; xs :\ z is the same as xs foldRight z.

Note: might return different results for different runs, unless the underlying collection type is ordered. or the operator is associative and commutative.

Examples:

Note that the folding function used to compute b is equivalent to that used to compute c.

     scala> val a = LinkedList(1,2,3,4)
     a: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2, 3, 4)

     scala> val b = (a :\ 5)(_+_)
     b: Int = 15

     scala> val c = (a :\ 5)((x,y) => x + y)
     c: Int = 15

Test two objects for equality. The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).

Appends all elements of this immutable sorted set to a string builder. The written text consists of the string representations (w.r.t. the method toString) of all elements of this immutable sorted set without any separator string.

Example:

     scala> val a = LinkedList(1,2,3,4)
     a: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2, 3, 4)

     scala> val b = new StringBuilder()
     b: StringBuilder =

     scala> val h = a.addString(b)
     b: StringBuilder = 1234

Appends all elements of this immutable sorted set to a string builder using a separator string. The written text consists of the string representations (w.r.t. the method toString) of all elements of this immutable sorted set, separated by the string sep.

Example:

     scala> val a = LinkedList(1,2,3,4)
     a: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2, 3, 4)

     scala> val b = new StringBuilder()
     b: StringBuilder =

     scala> a.addString(b, ", ")
     res0: StringBuilder = 1, 2, 3, 4

Appends all elements of this immutable sorted set to a string builder using start, end, and separator strings. The written text begins with the string start and ends with the string end. Inside, the string representations (w.r.t. the method toString) of all elements of this immutable sorted set are separated by the string sep.

Example:

     scala> val a = LinkedList(1,2,3,4)
     a: scala.collection.mutable.LinkedList[Int] = LinkedList(1, 2, 3, 4)

     scala> val b = new StringBuilder()
     b: StringBuilder =

     scala> a.addString(b, "LinkedList(", ", ", ")")
     res1: StringBuilder = LinkedList(1, 2, 3, 4)

Aggregates the results of applying an operator to subsequent elements.

This is a more general form of fold and reduce. It has similar semantics, but does not require the result to be a supertype of the element type. It traverses the elements in different partitions sequentially, using seqop to update the result, and then applies combop to results from different partitions. The implementation of this operation may operate on an arbitrary number of collection partitions, so combop may be invoked an arbitrary number of times.

For example, one might want to process some elements and then produce a Set. In this case, seqop would process an element and append it to the list, while combop would concatenate two lists from different partitions together. The initial value z would be an empty set.

   pc.aggregate(Set[Int]())(_ += process(_), _ ++ _)

Another example is calculating geometric mean from a collection of doubles (one would typically require big doubles for this).

Composes two instances of Function1 in a new Function1, with this function applied first.

Tests if some element is contained in this set.

This method is equivalent to contains. It allows sets to be interpreted as predicates.

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 expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(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 type.

Method called from equality methods, so that user-defined subclasses can refuse to be equal to other collections of the same kind.

Create a copy of the receiver object.

Needs to be overridden in subclasses.

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).

Compares this set with another object for equality.

Note: This operation contains an unchecked cast: if that is a set, it will assume with an unchecked cast that it has the same element type as this set. Any subsequent ClassCastException is treated as a false result.

The nature of the representation is platform dependent.

Partitions this immutable sorted set into a map of immutable sorted sets according to some discriminator function.

Note: this method is not re-implemented by views. This means when applied to a view it will always force the view and return a new immutable sorted set.

Partitions elements in fixed size immutable sorted sets.

Tests whether this immutable sorted set is known to have a finite size. All strict collections are known to have finite size. For a non-strict collection such as Stream, the predicate returns true if all elements have been computed. It returns false if the stream is not yet evaluated to the end.

Note: many collection methods will not work on collections of infinite sizes.

Computes the intersection between this set and another set.

Tests if this set is empty.

Test whether the dynamic type of the receiver object is T0.

Note that the result of the test is modulo Scala's erasure semantics. Therefore the expression 1.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 specified type.

Tests whether this immutable sorted set can be repeatedly traversed.

Selects the last element.

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

Wakes up a single thread that is waiting on the receiver object's monitor.

Wakes up all threads that are waiting on the receiver object's monitor.

Returns a parallel implementation of this collection.

For most collection types, this method creates a new parallel collection by copying all the elements. For these collection, par takes linear time. Mutable collections in this category do not produce a mutable parallel collection that has the same underlying dataset, so changes in one collection will not be reflected in the other one.

Specific collections (e.g. ParArray or mutable.ParHashMap) override this default behaviour by creating a parallel collection which shares the same underlying dataset. For these collections, par takes constant or sublinear time.

All parallel collections return a reference to themselves.

The default par implementation uses the combiner provided by this method to create a new parallel collection.
