public abstract class AbstractObject2BooleanMap<K> extends AbstractObject2BooleanFunction<K> implements Object2BooleanMap<K>, 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).

AbstractObject2BooleanMap.BasicEntry<K>
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).

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.
