Object	first() Returns the first (lowest) element currently in this sorted set.
SortedSet	getSortedSet() Return the underlying SortedSet.
SortedSet	headSet(Object toElement) Returns a view of the portion of this sorted set whose elements are strictly less than toElement.
protected SortedSet	instantiateSortedSet(SortedSet set, Converter convUp, Converter convDown) Create a Converter SortedSet.
Object	last() Returns the last (highest) element currently in this sorted set.
SortedSet	subSet(Object fromElement, Object toElement) Returns a view of the portion of this sorted set whose elements range from fromElement, inclusive, to toElement, exclusive.
SortedSet	tailSet(Object fromElement) Returns a view of the portion of this sorted set whose elements are greater than or equal to fromElement.

Constructor Detail

ConverterCollections.ConverterSortedSet

public ConverterCollections.ConverterSortedSet(SortedSet set,
                                               Converter convUp,
                                               Converter convDown)

Constructor.

Parameters:

set - the underlying SortedSet

convUp - the Converter from the underlying SortedSet

convDown - the Converter to the underlying SortedSet

Method Detail

comparator

public Comparator comparator()

Returns the comparator associated with this sorted set, or null if it uses its elements' natural ordering.

Specified by:

comparator in interface SortedSet

Returns:

the comparator associated with this sorted set, or null if it uses its elements' natural ordering

subSet

public SortedSet subSet(Object fromElement,
                        Object toElement)

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

Obeys the general contract of SortedSet.subSet.

Specified by:

subSet in interface SortedSet

Parameters:

fromElement - low endpoint (inclusive) of the subSet

toElement - high endpoint (exclusive) of the subSet

Returns:

a view of the specified range within this sorted set

headSet

public SortedSet headSet(Object toElement)

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

Obeys the general contract of SortedSet.headSet.

Specified by:

headSet in interface SortedSet

Parameters:

toElement - high endpoint (exclusive) of the headSet

Returns:

a view of the specified initial range of this sorted set

tailSet

public SortedSet tailSet(Object fromElement)

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

Obeys the general contract of SortedSet.tailSet.

Specified by:

tailSet in interface SortedSet

Parameters:

fromElement - low endpoint (inclusive) of the tailSet

Returns:

a view of the specified final range of this sorted set

first

public Object first()

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

Specified by:

first in interface SortedSet

Returns:

the first (lowest) element currently in this sorted set

Throws:

NoSuchElementException - if the sorted set is empty

last

public Object last()

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

Specified by:

last in interface SortedSet

Returns:

the last (highest) element currently in this sorted set

Throws:

NoSuchElementException - if the sorted set is empty

instantiateSortedSet

protected SortedSet instantiateSortedSet(SortedSet set,
                                         Converter convUp,
                                         Converter convDown)

Create a Converter SortedSet.

Parameters:

set - the underlying SortedSet

convUp - the Converter to view the underlying SortedSet through

convDown - the Converter to pass items down to the underlying SortedSet through

Returns:

a Converter SortedSet

getSortedSet

public SortedSet getSortedSet()

Return the underlying SortedSet.

Returns:

the underlying SortedSet
