public class DoubleSortedSetToSortedSetAdapter

extends DoubleSetToSetAdapter

implements SortedSet

This class represents adapters of double sets to Java Collections Framework sets. The adapter is implemented as a wrapper around a primitive set. Thus, changes to the underlying set are reflected by this set and vice versa.

Constructor Detail

DoubleSortedSetToSortedSetAdapter

public DoubleSortedSetToSortedSetAdapter(DoubleSortedSet set)

Creates a new adaption of a set of double values to a Java Collections Framework set.

Parameters:

set - the underlying primitive set.

Throws:

NullPointerException - if set is null.

Method Detail

comparator

public Comparator comparator()

Returns the comparator used by this set. This method always returns null, since primitive sets are sorted by their natural ordering.

Specified by:

comparator in interface SortedSet

Returns:

null.

first

public Object first()

Returns the lowest element of this set.

Specified by:

first in interface SortedSet

Returns:

the lowest element of this set.

Throws:

NoSuchElementException - if this set is empty.

headSet

public SortedSet headSet(Object to)

Returns the subset of values lower than a specified value. The returned subset is a view of this set, so changes to the subset are reflected by this set and vice versa.

Specified by:

headSet in interface SortedSet

Parameters:

to - the upper bound of the returned set (not included).

Throws:

IllegalArgumentException - if to is not permitted in this set (which can be the case with returned subsets).

ClassCastException - if to is not of class Double.

NullPointerException - if to is null.

last

public Object last()

Returns the highest element of this set.

Specified by:

last in interface SortedSet

Returns:

the highest element of this set.

Throws:

NoSuchElementException - if this set is empty.

subSet

public SortedSet subSet(Object from,
                        Object to)

Returns the subset of values lower that a specified value and higher than or equal to another specified value. The returned subset is a view of this set, so changes to the subset are reflected by this set and vice versa.

Specified by:

subSet in interface SortedSet

Parameters:

from - the lower bound of the returned set (included).

to - the upper bound of the returned set (not included).

Throws:

IllegalArgumentException - if from is greater than to; if from or to is not permitted in this set (which can be the case with returned subsets).

ClassCastException - if from is not of class Double; if to is not of class Double.

NullPointerException - if from is null; if to is null.

tailSet

public SortedSet tailSet(Object from)

Returns the subset of values higher than or equal to a specified value. The returned subset is a view of this set, so changes to the subset are reflected by this set and vice versa.

Specified by:

tailSet in interface SortedSet

Parameters:

from - the lower bound of the returned set (included).

Throws:

IllegalArgumentException - if from is not permitted in this set (which can be the case with returned subsets).

ClassCastException - if from is not of class Double.

NullPointerException - if from is null.
