AbstractSetValuedMap (The Adobe AEM Quickstart and Web Application. 6.6.2)

java.lang.Object
- org.apache.commons.collections4.multimap.AbstractMultiValuedMap<K,V>
- - org.apache.commons.collections4.multimap.AbstractSetValuedMap<K,V>

Type Parameters:

K - the type of the keys in this map

V - the type of the values in this map

All Implemented Interfaces:

MultiValuedMap<K,V>, SetValuedMap<K,V>

Direct Known Subclasses:

HashSetValuedHashMap, LinkedHashSetValuedLinkedHashMap
```
public abstract class AbstractSetValuedMap<K,V>
extends AbstractMultiValuedMap<K,V>
implements SetValuedMap<K,V>
```
Abstract implementation of the SetValuedMap interface to simplify the creation of subclass implementations.
Subclasses specify a Map implementation to use as the internal storage and the Set implementation to use as values.

4.1

- Method Detail
  - get
```
public java.util.Set<V> get(K key)
```
    Gets the set of values associated with the specified key. This would return an empty set in case the mapping is not present
    
    Specified by:
    
    get in interface MultiValuedMap<K,V>
    
    Specified by:
    
    get in interface SetValuedMap<K,V>
    
    Overrides:
    
    get in class AbstractMultiValuedMap<K,V>
    
    Parameters:
    
    key - the key to retrieve
    
    Returns:
    
    the Set of values, will return an empty Set for no mapping
  - remove
```
public java.util.Set<V> remove(java.lang.Object key)
```
    Removes all values associated with the specified key.
    A subsequent get(Object) would return an empty set.
    
    Specified by:
    
    remove in interface MultiValuedMap<K,V>
    
    Specified by:
    
    remove in interface SetValuedMap<K,V>
    
    Overrides:
    
    remove in class AbstractMultiValuedMap<K,V>
    
    Parameters:
    
    key - the key to remove values from
    
    Returns:
    
    the Set of values removed, will return an empty, unmodifiable set for no mapping found.
