Type Parameters

T

Implements a Set based on a Dictionary (which is equivalent of non-genric HashTable) This will give the best lookup, add, and remove performance for very large data-sets, but iteration will occur in no particular order.

The following tables list the members exposed by the HashedSet<(Of T>) generic type.

Public Methods

	Name	Description
	Add	Adds the specified element to this set if it is not already present. Adds the specified element to this set if it is not already present. (Inherited from DictionarySet<(Of T>).)
	AddAll	Adds all the elements in the specified collection to the set if they are not already present. Adds all the elements in the specified collection to the set if they are not already present. (Inherited from DictionarySet<(Of T>).)
	Clear	Removes all objects from the set. Removes all objects from the set. (Inherited from DictionarySet<(Of T>).)
	Clone	Returns a clone of the Set instance. This will work for derived Set classes if the derived class implements a constructor that takes no arguments. Returns a clone of the Set instance. This will work for derived Set classes if the derived class implements a constructor that takes no arguments. (Inherited from Set<(Of T>).)
	Contains	Returns trueTruetrue if this set contains the specified element. Returns trueTruetrue if this set contains the specified element. (Inherited from DictionarySet<(Of T>).)
	ContainsAll	Returns trueTruetrue if the set contains all the elements in the specified collection. Returns trueTruetrue if the set contains all the elements in the specified collection. (Inherited from DictionarySet<(Of T>).)
	CopyTo	Copies the elements in the Set to an array of T. The type of array needs to be compatible with the objects in the Set, obviously. Copies the elements in the Set to an array of T. The type of array needs to be compatible with the objects in the Set, obviously. (Inherited from DictionarySet<(Of T>).)
	ExclusiveOr	Performs an "exclusive-or" of the two sets, keeping only the elements that are in one of the sets, but not in both. The original sets are not modified during this operation. The result set is a Clone() of this set containing the elements from the exclusive-or operation. (Inherited from Set<(Of T>).)
	GetEnumerator	Gets an enumerator for the elements in the Set. Gets an enumerator for the elements in the Set. (Inherited from DictionarySet<(Of T>).)
	Intersect	Performs an "intersection" of the two sets, where only the elements that are present in both sets remain. That is, the element is included if it exists in both sets. The Intersect() operation does not modify the input sets. It returns a Clone() of this set with the appropriate elements removed. (Inherited from Set<(Of T>).)
	Minus	Performs a "minus" of set b from set a. This returns a set of all the elements in set a, removing the elements that are also in set b. The original sets are not modified during this operation. The result set is a Clone() of this Set containing the elements from the operation. (Inherited from Set<(Of T>).)
	Remove	Removes the specified element from the set. Removes the specified element from the set. (Inherited from DictionarySet<(Of T>).)
	RemoveAll	Remove all the specified elements from this set, if they exist in this set. Remove all the specified elements from this set, if they exist in this set. (Inherited from DictionarySet<(Of T>).)
	RetainAll	Retains only the elements in this set that are contained in the specified collection. Retains only the elements in this set that are contained in the specified collection. (Inherited from DictionarySet<(Of T>).)
	Union	Performs a "union" of the two sets, where all the elements in both sets are present. That is, the element is included if it is in either a or b. Neither this set nor the input set are modified during the operation. The return value is a Clone() of this set with the extra elements added in. (Inherited from Set<(Of T>).)

Protected Methods

	Name	Description
	NonGenericCopyTo	Copies the elements in the Set to an array. The type of array needs to be compatible with the objects in the Set, obviously. Needed for non-generic ISet methods implementation Copies the elements in the Set to an array. The type of array needs to be compatible with the objects in the Set, obviously. Needed for non-generic ISet methods implementation (Inherited from DictionarySet<(Of T>).)
	NonGenericExclusiveOr	Performs ExclusiveOr when called trhough non-generic ISet interface Performs ExclusiveOr when called trhough non-generic ISet interface (Inherited from Set<(Of T>).)
	NonGenericIntersect	Performs Intersect when called trhough non-generic ISet interface Performs Intersect when called trhough non-generic ISet interface (Inherited from Set<(Of T>).)
	NonGenericMinus	Performs Minus when called trhough non-generic ISet interface Performs Minus when called trhough non-generic ISet interface (Inherited from Set<(Of T>).)
	NonGenericUnion	Performs Union when called trhough non-generic ISet interface Performs Union when called trhough non-generic ISet interface (Inherited from Set<(Of T>).)

Protected Fields

	Name	Description
	InternalDictionary	Provides the storage for elements in the Set, stored as the key-set of the IDictionary object. Set this object in the constructor if you create your own Set class. Provides the storage for elements in the Set, stored as the key-set of the IDictionary object. Set this object in the constructor if you create your own Set class. (Inherited from DictionarySet<(Of T>).)

Public Constructors

Public Properties

	Name	Description
	Count	The number of elements contained in this collection. The number of elements contained in this collection. (Inherited from DictionarySet<(Of T>).)
	IsEmpty	Returns trueTruetrue if this set contains no elements. Returns trueTruetrue if this set contains no elements. (Inherited from DictionarySet<(Of T>).)
	IsReadOnly	Indicates wether the Set is read-only or not Indicates wether the Set is read-only or not (Inherited from DictionarySet<(Of T>).)
	IsSynchronized	None of the objects based on DictionarySet are synchronized. Use the SyncRoot property instead. None of the objects based on DictionarySet are synchronized. Use the SyncRoot property instead. (Inherited from DictionarySet<(Of T>).)
	SyncRoot	Returns an object that can be used to synchronize the Set between threads. Returns an object that can be used to synchronize the Set between threads. (Inherited from DictionarySet<(Of T>).)
