Overrides java.util.HashMap.clear.

Implements java.util.Map.clear.

Doc from java.util.HashMap.clear.

Removes all of the mappings from this map. The map will be empty after this call returns.

Overrides java.util.HashMap.entrySet.

Implements java.util.Map.entrySet.

Doc from java.util.HashMap.entrySet.

Returns a Set view of the mappings contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation, or through the setValue operation on a map entry returned by the iterator) the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.

Returns:Set<E>

a set view of the mappings contained in this map

Overrides java.util.HashMap.keySet.

Implements java.util.Map.keySet.

Doc from java.util.HashMap.keySet.

Returns a Set view of the keys contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations.

Returns:Set<E>

a set view of the keys contained in this map

Overrides java.util.HashMap.put.

Implements java.util.Map.put.

Doc from java.util.HashMap.put.

Associates the specified value with the specified key in this map. If the map previously contained a mapping for the key, the old value is replaced.

Parameters

key:Object

key with which the specified value is to be associated

value:Object

value to be associated with the specified key

Returns:Object

the previous value associated with key, or null if there was no mapping for key. (A null return can also indicate that the map previously associated null with key.)

Overrides java.util.HashMap.putAll.

Implements java.util.Map.putAll.

Doc from java.util.HashMap.putAll.

Copies all of the mappings from the specified map to this map. These mappings will replace any mappings that this map had for any of the keys currently in the specified map.

Parameters

m:Map<K, V>

mappings to be stored in this map

Overrides java.util.HashMap.remove.

Implements java.util.Map.remove.

Doc from java.util.HashMap.remove.

Removes the mapping for the specified key from this map if present.

Parameters

key:Object

key whose mapping is to be removed from the map

Returns:Object

the previous value associated with key, or null if there was no mapping for key. (A null return can also indicate that the map previously associated null with key.)

Overrides java.util.HashMap.values.

Implements java.util.Map.values.

Doc from java.util.HashMap.values.

Returns a Collection view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa. If the map is modified while an iteration over the collection is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The collection supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Collection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.

Returns:Collection<E>

a view of the values contained in this map
