```
protected final Map<K,List<V>> store
```
    Backing store for the [key, multi-value] pairs.
- Constructor Detail
  - AbstractMultivaluedMap
```
public AbstractMultivaluedMap(Map<K,List<V>> store)
```
    Initialize the backing store in the abstract parent multivalued map implementation.
    
    Parameters:
    store - the backing Map to be used as a [key, multi-value] store. Must not be null.
    
    Throws:
    
    NullPointerException - in case the underlying store parameter is null.
- Method Detail
  - putSingle
```
public final void putSingle(K key,
             V value)
```
    Set the value for the key to be a one item list consisting of the supplied value. Any existing values will be replaced.
    NOTE: This implementation ignores null values; A supplied value of null is ignored and not added to the purged value list. As a result of such operation, empty value list would be registered for the supplied key. Overriding implementations may modify this behavior by redefining the addNull(java.util.List) method.
    
    Specified by:
    
    putSingle in interface MultivaluedMap<K,V>
    
    Parameters:
    key - the key
    value - the single value of the key. If the value is null it will be ignored.
  - addNull
```
protected void addNull(List<V> values)
```
    Define the behavior for adding a null values to the value list.
    Default implementation is a no-op, i.e. the null values are ignored. Overriding implementations may modify this behavior by providing their own definitions of this method.
    
    Parameters:
    values - value list where the null value addition is being requested.
  - addFirstNull
```
protected void addFirstNull(List<V> values)
```
    Define the behavior for adding a null values to the first position in the value list.
    Default implementation is a no-op, i.e. the null values are ignored. Overriding implementations may modify this behavior by providing their own definitions of this method.
    
    Parameters:
    values - value list where the null value addition is being requested.
  - add
```
public final void add(K key,
       V value)
```
    Add a value to the current list of values for the supplied key.
    NOTE: This implementation ignores null values; A supplied value of null is ignored and not added to the value list. Overriding implementations may modify this behavior by redefining the addNull(java.util.List) method.
    
    Specified by:
    
    add in interface MultivaluedMap<K,V>
    
    Parameters:
    key - the key
    value - the value to be added.
  - addAll
```
public final void addAll(K key,
          V... newValues)
```
    Add multiple values to the current list of values for the supplied key. If the supplied array of new values is empty, method returns immediately. Method throws a NullPointerException if the supplied array of values is null.
    NOTE: This implementation ignores null values; Any of the supplied values of null is ignored and not added to the value list. Overriding implementations may modify this behavior by redefining the addNull(java.util.List) method.
    
    Specified by:
    
    addAll in interface MultivaluedMap<K,V>
    
    Parameters:
    key - the key.
    newValues - the values to be added.

    NullPointerException - if the supplied array of new values is null.
  - addAll
```
public final void addAll(K key,
          List<V> valueList)
```
    Add all the values from the supplied value list to the current list of values for the supplied key. If the supplied value list is empty, method returns immediately. Method throws a NullPointerException if the supplied array of values is null.
    NOTE: This implementation ignores null values; Any null value in the supplied value list is ignored and not added to the value list. Overriding implementations may modify this behavior by redefining the addNull(java.util.List) method.
    
    Specified by:
    
    addAll in interface MultivaluedMap<K,V>
    
    Parameters:
    key - the key.

    getFirst in interface MultivaluedMap<K,V>
    
    Parameters:
    key - the key
    
    Returns:
    the first value for the specified key or null if the key is not in the map.
  - addFirst
```
public final void addFirst(K key,
            V value)
```
    Add a value to the first position in the current list of values for the supplied key.
    NOTE: This implementation ignores null values; A supplied value of null is ignored and not added to the purged value list. Overriding implementations may modify this behavior by redefining the addFirstNull(java.util.List) method.

    addFirst in interface MultivaluedMap<K,V>
    
    Parameters:
    key - the key
    value - the value to be added.

```
protected final List<V> getValues(K key)
```
    Return a non-null list of values for a given key. The returned list may be empty.
    If there is no entry for the key in the map, a new empty List instance is created, registered within the map to hold the values of the key and returned from the method.
    
    Parameters:
    key - the key.
    
    Returns:
    value list registered with the key. The method is guaranteed to never return null.
