| abstract protected Object | baseToDerived(Object key)
Transforms a key from the
map to a key in this map.
If there is no key in the derived map for the specified base key,
then this method returns
null .
Parameters:
key - A ley from the map. |
| public boolean | containsKey(Object key)
Returns
true if this map contains a mapping for the specified key.
The default implementation invokes
.containsKey(
(key)).
Parameters:
key - key whose presence in this map is to be tested. |
| public boolean | containsValue(Object value)
Returns
true if this map maps one or more keys to this value. |
| abstract protected Object | derivedToBase(Object key)
Transforms a key from this derived map to a key in the
map.
Parameters:
key - A key in this map. |
| public Set | entrySet()
Returns a set view of the mappings contained in this map. |
| public Object | get(Object key)
Returns the value to which this map maps the specified key.
The default implementation invokes
.get(
(key)).
Parameters:
key - key whose associated value is to be returned. |
| public boolean | isEmpty()
Returns
true if this map contains no key-value mappings. |
| public Set | keySet()
Returns a set view of the keys contained in this map. |
| public Object | put(Object key, Object value)
Associates the specified value with the specified key in this map.
The default implementation invokes
.put(
(key), value).
Parameters:
key - key with which the specified value is to be associated.
Parameters:
value - value to be associated with the specified key. |
| public Object | remove(Object key)
Removes the mapping for this key from this map if present.
The default implementation invokes
.remove(
(key)).
Parameters:
key - key whose mapping is to be removed from the map. |
| public int | size()
Returns the number of key-value mappings in this map. |
| public Collection | values()
Returns a collection view of the values contained in this map. |
