add
public boolean add(float k)
Description copied from class:AbstractFloatCollection
Ensures that this collection contains the specified element (optional operation).This implementation always throws an
UnsupportedOperationException
.- Specified by:
add
in interfaceFloatCollection
- Overrides:
add
in classAbstractFloatCollection
- See Also:
Collection.add(Object)
-
remove
public boolean remove(float k)
Description copied from class:AbstractFloatSet
Removes an element from this set.Note that the corresponding method of a type-specific collection is
rem()
. This unfortunate situation is caused by the clash with the similarly named index-based method in theList
interface. Delegates to the type-specificrem()
method implemented by type-specific abstractCollection
superclass.- Specified by:
remove
in interfaceFloatSet
- Overrides:
remove
in classAbstractFloatSet
- See Also:
Collection.remove(Object)
-
contains
public boolean contains(float k)
Description copied from class:AbstractFloatCollection
Returnstrue
if this collection contains the specified element.This implementation iterates over the elements in the collection, looking for the specified element.
- Specified by:
contains
in interfaceFloatCollection
- Overrides:
contains

in interfaceFloatSortedSet
- See Also:

-
iterator
public FloatBidirectionalIterator iterator()
Description copied from interface:FloatCollection
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 extendsCollection

iterator
public FloatBidirectionalIterator iterator(float from)
Description copied from interface:FloatSortedSet
Returns a type-specificBidirectionalIterator
on the elements in this set, starting from a given element of the domain (optional operation).This method returns a type-specific bidirectional iterator with given starting point. The starting point is any element comparable to the elements of this set (even if it does not actually belong to the set). The next element of the returned iterator is the least element of the set that is greater than the starting point (if there are no elements greater than the starting point,
hasNext()
will returnfalse
). The previous element of the returned iterator is the greatest element of the set that is smaller than or equal to the starting point (if there are no elements smaller than or equal to the starting point,hasPrevious()
will returnfalse
).Note that passing the last element of the set as starting point and calling
previous()
you can traverse the entire set in reverse order.- Specified by:
iterator
in interfaceFloatSortedSet
- Parameters:
from
- an element to start from.- Returns:
- a bidirectional iterator on the element in this set, starting at the given element.
-

clone
public Object clone()
Returns a deep copy of this tree set.This method performs a deep copy of this tree set; the data stored in the set, however, is not cloned. Note that this makes a difference only for object keys.
