SortedMap	getSortedMap() Return the underlying SortedMap.
SortedMap	headMap(Object toKey) Returns a view of the portion of this sorted map whose keys are strictly less than toKey.
protected SortedMap	instantiateSortedMap(SortedMap map, Converter convKeyUp, Converter convKeyDown, Converter convValUp, Converter convValDown) Create a Converter SortedMap.
Object	lastKey() Returns the last (highest) key currently in this sorted map.
SortedMap	subMap(Object fromKey, Object toKey) Returns a view of the portion of this sorted map whose keys range from fromKey, inclusive, to toKey, exclusive.
SortedMap	tailMap(Object fromKey) Returns a view of the portion of this sorted map whose keys are greater than or equal to fromKey.

Constructor.

Parameters:

map - the underlying SortedMap

convKeyUp - the Converter to view the underlying SortedMap's keys through

convKeyDown - the Converter to use to pass keys down to the underlying SortedMap

convValUp - the Converter to view the underlying SortedMap's values through

convValDown - the Converter to use to pass values down to the underlying SortedMap

Method Detail

comparator

public Comparator comparator()

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

Specified by:

comparator in interface SortedMap

Returns:

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

subMap

public SortedMap subMap(Object fromKey,
                        Object toKey)

Returns a view of the portion of this sorted map whose keys range from fromKey, inclusive, to toKey, exclusive. Obeys the general contract of SortedMap.subMap.

Specified by:

subMap in interface SortedMap

Parameters:

fromKey - low endpoint (inclusive) of the subMap

toKey - high endpoint (exclusive) of the subMap

Returns:

a view of the specified range within this sorted map

headMap

public SortedMap headMap(Object toKey)

Returns a view of the portion of this sorted map whose keys are strictly less than toKey.

Specified by:

headMap in interface SortedMap

Parameters:

toKey - high endpoint (exclusive) of the subMap

Returns:

a view of the specified initial range of this sorted map

tailMap

public SortedMap tailMap(Object fromKey)

Returns a view of the portion of this sorted map whose keys are greater than or equal to fromKey.

Specified by:

tailMap in interface SortedMap

Parameters:

fromKey - low endpoint (inclusive) of the tailMap

Returns:

a view of the specified final range of this sorted map

firstKey

public Object firstKey()

Returns the first (lowest) key currently in this sorted map.

Specified by:

firstKey in interface SortedMap

Returns:

the first (lowest) key currently in this sorted map

lastKey

public Object lastKey()

Returns the last (highest) key currently in this sorted map.

Specified by:

lastKey in interface SortedMap

Returns:

the last (highest) key currently in this sorted map

instantiateSortedMap

protected SortedMap instantiateSortedMap(SortedMap map,
                                         Converter convKeyUp,
                                         Converter convKeyDown,
                                         Converter convValUp,
                                         Converter convValDown)

Create a Converter SortedMap.

Parameters:

map - the underlying SortedMap

convKeyUp - the Converter to view the underlying SortedMap's keys through

convKeyDown - the Converter to use to pass keys down to the underlying SortedMap

convValUp - the Converter to view the underlying SortedMap's values through

convValDown - the Converter to use to pass values down to the underlying SortedMap

Returns:

a Converter SortedMap

getSortedMap

public SortedMap getSortedMap()
