public abstract class AbstractDouble2CharMap extends AbstractDouble2CharFunction implements Double2CharMap, Serializable
Optional operations just throw an UnsupportedOperationException
. Generic versions of accessors delegate to
the corresponding type-specific counterparts following the interface rules
(they take care of returning null
on a missing key).
As a further help, this class provides a BasicEntry
inner class
that implements a type-specific version of Map.Entry
; it
is particularly useful for those classes that do not implement their own
entries (e.g., most immutable maps).

AbstractDouble2CharMap.BasicEntry
This class provides a basic but complete type-specific entry class for all those maps implementations
that do not have entries on their own (e.g., most immutable maps).

hashCode()
Returns a hash code for this map.
|
boolean |
isEmpty() |
DoubleSet |
keySet()
Returns a type-specific-set view of the keys of this map.

The view is backed by the set returned by 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.
