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
