Remarks
This class provides a skeletal implementation of the Map
interface, to minimize the effort required to implement this interface.
To implement an unmodifiable map, the programmer needs only to extend this class and provide an implementation for the entrySet
method, which returns a set-view of the map's mappings. Typically, the returned set will, in turn, be implemented atop AbstractSet
. This set should not support the add
or remove
methods, and its iterator should not support the remove
method.
To implement a modifiable map, the programmer must additionally override this class's put
method (which otherwise throws an UnsupportedOperationException
), and the iterator returned by entrySet().iterator()
must additionally implement its remove
method.
The programmer should generally provide a void (no argument) and map constructor, as per the recommendation in the Map
interface specification.
The documentation for each non-abstract method in this class describes its implementation in detail. Each of these methods may be overridden if the map being implemented admits a more efficient implementation.
This class is a member of the Java Collections Framework.
