Method Detail

toArray

public int[] 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.

This implementation allocates the array to be returned, and iterates over the elements in the collection, storing each object reference in the next consecutive element of the array, starting with element 0.

Specified by:

toArray in interface IntSet

Returns:

an array containing all of the elements in this collection.

isEmpty

public boolean isEmpty()

Description copied from interface: IntSet

Returns true if this set contains no elements.

Specified by:

isEmpty in interface IntSet

Returns:

true if this set contains no elements.

contains

public boolean contains(int o)

Description copied from interface: IntSet

Returns true if this set contains the specified element.

Specified by:

contains in interface IntSet

Parameters:

o - element whose presence in this set is to be tested.

Returns:

true if this set contains the specified element.

containsAll

public boolean containsAll(IntSet c)

Description copied from interface: IntSet

Returns true if this set contains all of the elements in the specified set

Specified by:

containsAll in interface IntSet

Returns:

true if this set is a superset of the given set

add

public boolean add(int o)

Description copied from interface: IntSet

Adds the specified element to this set if it is not already present.

Specified by:

add in interface IntSet

Parameters:

o - element to be added to this set.

Returns:

true if the set did not already contain the specified element.

equals
