Method Detail

iterator

public abstract DoubleIterator iterator()

Description copied from interface: DoubleCollection

Returns a type-specific iterator on the elements of this collection.

Note that this specification strengthens the one given in Iterable.iterator(), which was already strengthened in the corresponding type-specific class, but was weakened by the fact that this interface extends Collection.

Specified by:

iterator in interface DoubleCollection

Specified by:

iterator in interface DoubleIterable

Specified by:

iterator in interface DoubleSet

Specified by:

iterator in interface Iterable<Double>

Specified by:

iterator in interface Collection<Double>

Specified by:

iterator in interface Set<Double>

Specified by:

iterator in class AbstractDoubleCollection

Returns:

a type-specific iterator on the elements of this collection.

equals

public boolean equals(Object o)

Specified by:

equals in interface Collection<Double>

Specified by:

equals in interface Set<Double>

Overrides:

equals in class Object

hashCode

public int hashCode()

Returns a hash code for this set. The hash code of a set is computed by summing the hash codes of its elements.

Specified by:

hashCode in interface Collection<Double>

Specified by:

hashCode in interface Set<Double>

Overrides:

hashCode in class Object

Returns:

a hash code for this set.

remove

public boolean remove(double k)

Description copied from interface: DoubleSet

Removes an element from this set.

Note that the corresponding method of the type-specific collection is rem(). This unfortunate situation is caused by the clash with the similarly named index-based method in the List interface.

Specified by:

remove in interface DoubleSet

See Also:

Collection.remove(Object)

rem

public boolean rem(double k)

Delegates to remove().

Specified by:

rem in interface DoubleCollection

Overrides:

rem in class AbstractDoubleCollection

Parameters:

k - the element to be removed.

Returns:

true if the set was modified.

See Also:

Collection.remove(Object)

remove

public boolean remove(Object o)

Delegates to the corresponding type-specific method.

Specified by:

remove in interface Collection<Double>

Specified by:

remove in interface Set<Double>

Overrides:

remove in class AbstractDoubleCollection
