HashSet Class

Definition

This class implements the Set interface, backed by a hash table (actually a HashMap instance).

Constructors

HashSet()

Constructs a new, empty set; the backing HashMap instance has default initial capacity (16) and load factor (0.

HashSet(ICollection)

Constructs a new set containing the elements in the specified collection.

HashSet(Int32)

Constructs a new, empty set; the backing HashMap instance has the specified initial capacity and default load factor (0.

HashSet(Int32, Single)

Constructs a new, empty set; the backing HashMap instance has the specified initial capacity and the specified load factor.

HashSet(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.
