Method Summary

Comparator	comparator() Returns the comparator associated with this sorted map, or null if it uses its keys' natural ordering.
Object	firstKey() Returns the first (lowest) key currently in this sorted map.
SortedMap	headMap(Object toKey) Returns a view of the portion of this sorted map whose keys are strictly less than toKey.
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 Detail

RestrictedCollections.RestrictedSortedMap

public RestrictedCollections.RestrictedSortedMap(Map map,
                                                 Class clzKey,
                                                 Class clzVal)

Constructor.

Parameters:

map - the underlying SortedMap

clzKey - the class of keys that may be stored in the Map

clzVal - the class of values that may be stored in the Map

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
