Method Detail

iterator

public DoubleBidirectionalIterator iterator(double from)

Description copied from interface: DoubleSortedSet

Returns a type-specific BidirectionalIterator 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 return false). 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 return false).

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 interface DoubleSortedSet

Parameters:

from - an element to start from.

Returns:

a bidirectional iterator on the element in this set, starting at the given element.

comparator

public DoubleComparator comparator()

Description copied from interface: DoubleSortedSet

Returns the comparator used to order the elements in this set, or null if this set uses the natural ordering of its elements.

Note that this specification strengthens the one given in SortedSet.comparator().

Specified by:

comparator in interface DoubleSortedSet

Specified by:

comparator in interface SortedSet<Double>

Returns:

the comparator used to order the elements in this set, or null if this set uses the natural ordering of its elements

subSet

public DoubleSortedSet subSet(double from,
                              double to)

Description copied from interface: DoubleSortedSet

Returns a view of the portion of this sorted set whose elements range from fromElement, inclusive, to toElement, exclusive.

Note that this specification strengthens the one given in SortedSet.subSet(Object,Object).

Specified by:

subSet in interface DoubleSortedSet

See Also:

SortedSet.subSet(Object,Object)

headSet

public DoubleSortedSet headSet(double to)

Description copied from interface: DoubleSortedSet

Returns a view of the portion of this sorted set whose elements are strictly less than toElement.

Note that this specification strengthens the one given in SortedSet.headSet(Object).

Specified by:

headSet in interface DoubleSortedSet

See Also:

SortedSet.headSet(Object)

tailSet

public DoubleSortedSet tailSet(double from)

Description copied from interface: DoubleSortedSet

Returns a view of the portion of this sorted set whose elements are greater than or equal to fromElement.

Note that this specification strengthens the one given in SortedSet.headSet(Object).

Specified by:

tailSet in interface DoubleSortedSet

See Also:

SortedSet.tailSet(Object)

firstDouble

public double firstDouble()

Description copied from interface: DoubleSortedSet

Returns the first (lowest) element currently in this set.

Specified by:

firstDouble in interface DoubleSortedSet

See Also:

SortedSet.first()

lastDouble

public double lastDouble()

Description copied from interface: DoubleSortedSet

Returns the last (highest) element currently in this set.

Specified by:

lastDouble in interface DoubleSortedSet

See Also:

SortedSet.last()

subSet

@Deprecated
public DoubleSortedSet subSet(Double from,
                                          Double to)

Deprecated. Please use the corresponding type-specific method instead.

Returns a view of the portion of this set whose elements range from fromElement, inclusive, to toElement, exclusive. (If fromElement and toElement are equal, the returned set is empty.) The returned set is backed by this set, so changes in the returned set are reflected in this set, and vice-versa. The returned set supports all optional set operations that this set supports.

The returned set will throw an IllegalArgumentException on an attempt to insert an element outside its range.

Specified by:

subSet in interface DoubleSortedSet

Specified by:

subSet in interface SortedSet<Double>

Parameters:

from - low endpoint (inclusive) of the returned set

to - high endpoint (exclusive) of the returned set

Returns:

a view of the portion of this set whose elements range from fromElement, inclusive, to toElement, exclusive

headSet

@Deprecated
public DoubleSortedSet headSet(Double to)

Deprecated. Please use the corresponding type-specific method instead.

Returns a view of the portion of this set whose elements are strictly less than toElement. The returned set is backed by this set, so changes in the returned set are reflected in this set, and vice-versa. The returned set supports all optional set operations that this set supports.

The returned set will throw an IllegalArgumentException on an attempt to insert an element outside its range.

Specified by:

headSet in interface DoubleSortedSet

Specified by:

headSet in interface SortedSet<Double>

Parameters:

to - high endpoint (exclusive) of the returned set

Returns:

a view of the portion of this set whose elements are strictly less than toElement

tailSet

@Deprecated
public DoubleSortedSet tailSet(Double from)

Deprecated. Please use the corresponding type-specific method instead.

Returns a view of the portion of this set whose elements are greater than or equal to fromElement. The returned set is backed by this set, so changes in the returned set are reflected in this set, and vice-versa. The returned set supports all optional set operations that this set supports.

The returned set will throw an IllegalArgumentException on an attempt to insert an element outside its range.

Specified by:

tailSet in interface DoubleSortedSet

Specified by:

tailSet in interface SortedSet<Double>

Parameters:

from - low endpoint (inclusive) of the returned set

Returns:

a view of the portion of this set whose elements are greater than or equal to fromElement

first in interface DoubleSortedSet

Specified by:

first in interface SortedSet<Double>

Returns:

the first (lowest) element currently in this set

last

@Deprecated
public Double last()

Deprecated. Please use the corresponding type-specific method instead.
