SortedSet<T>.IsSupersetOf(IEnumerable<T>) Method

Definition

Namespace:

System.Collections.Generic

Assembly:

System.Collections.dll

Source:

SortedSet.cs

Determines whether a SortedSet<T> object is a superset of the specified collection.

public:
 virtual bool IsSupersetOf(System::Collections::Generic::IEnumerable<T> ^ other);

public bool IsSupersetOf (System.Collections.Generic.IEnumerable<T> other);

abstract member IsSupersetOf : seq<'T> -> bool
override this.IsSupersetOf : seq<'T> -> bool

Public Function IsSupersetOf (other As IEnumerable(Of T)) As Boolean

Parameters

other

IEnumerable<T>

The collection to compare to the current SortedSet<T> object.

Returns

Boolean

true if the SortedSet<T> object is a superset of other; otherwise, false.

Implements

IsSupersetOf(IEnumerable<T>) IsSupersetOf(IEnumerable<T>)

Exceptions

ArgumentNullException

other is null.

Remarks

All collections, including the empty set, are supersets of the empty set. Therefore, this method returns true if the collection represented by the other parameter is empty, even if the current SortedSet<T> object is empty.

This method always returns false if Count is less than the number of elements in other.

If the collection represented by other is a SortedSet<T> collection with the same equality comparer as the current SortedSet<T> object, this method is an O(n) operation. Otherwise, this method is an O(n + m) operation, where n is the number of elements in other and m is Count.
