Method Detail

headMap

public SortedMap headMap(Object to)
Delegates to the corresponding type-specific method.

Specified by:
headMap in interface SortedMap

tailMap

public SortedMap tailMap(Object from)
Delegates to the corresponding type-specific method.

Specified by:
tailMap in interface SortedMap

subMap

public SortedMap subMap(Object from,
                        Object to)
Delegates to the corresponding type-specific method.

Specified by:
subMap in interface SortedMap

firstKey

public Object firstKey()
Delegates to the corresponding type-specific method.

Specified by:
firstKey in interface SortedMap

lastKey

public Object lastKey()
Delegates to the corresponding type-specific method.

Specified by:
lastKey in interface SortedMap

keySet

public Set keySet()
Returns a type-specific-sorted-set view of the keys of this map.

The view is backed by the sorted set returned by Map.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.

Specified by:
keySet in interface Map
Overrides:
keySet in class AbstractDouble2ReferenceMap
Returns:
a sorted set view of the keys of this map; it may be safely cast to a type-specific interface.
