    • iterator

      public Iterator iterator()
      Returns an iterator over the elements contained in this collection.
      Specified by:
      iterator in interface Collection
      Specified by:
      iterator in interface Iterable
      Specified by:
      iterator in interface Set
      Specified by:
      iterator in class AbstractCollection
      Returns:
      an iterator over the elements contained in this collection

    • size

      public int size()
      Returns the number of elements in this collection. If the collection contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.
      Specified by:
      size in interface Collection
      Specified by:
      size in interface Set
      Specified by:
      size in class AbstractCollection
      Returns:
      the number of elements in this collection.

    • contains

      public boolean contains(Object o)
      Returns true if this collection contains the specified element. More formally, returns true if and only if this collection contains at least one element e such that (o==null ? e==null : o.equals(e)).

      Specified by:
      contains in interface Collection
      Specified by:
      contains in interface Set
      Overrides:
      contains in class AbstractCollection
      Parameters:
      o - object to be checked for containment in this collection
      Returns:
      true if this collection contains the specified element

    • clear

      public void clear()
      Removes all of the elements from this set of Keys by clearing the underlying Map.
      Specified by:
      clear in interface Collection
      Specified by:
      clear in interface Set
      Overrides:
      clear in class AbstractCollection

    • toArray

      public Object[] toArray()
      Returns an array containing all of the elements in this collection. If the collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order. The returned array will be "safe" in that no references to it are maintained by the collection. (In other words, this method must allocate a new array even if the collection is backed by an Array). The caller is thus free to modify the returned array.

      Specified by:
      toArray in interface Collection
      Specified by:
      toArray in interface Set
      Overrides:
      toArray in class AbstractCollection
      Returns:
      an array containing all of the elements in this collection

    • toArray

      public Object[] toArray(Object[] ao)
      Returns an array with a runtime type is that of the specified array and that contains all of the keys in this Set. If the Set fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the runtime type of the specified array and the size of this collection.

      If the Set fits in the specified array with room to spare (i.e., the array has more elements than the Set), the element in the array immediately following the end of the Set is set to null. This is useful in determining the length of the Set only if the caller knows that the Set does not contain any null keys.)

      Specified by:
      toArray in interface Collection
      Specified by:
      toArray in interface Set
      Overrides:
      toArray in class AbstractCollection
      Parameters:
      ao - the array into which the elements of the Set are to be stored, if it is big enough; otherwise, a new array of the same runtime type is allocated for this purpose
      Returns:
      an array containing the elements of the Set
      Throws:
      ArrayStoreException - if the runtime type of the specified array is not a supertype of the runtime type of every element in this Set of keys
