Method Detail
-
putSingle
void putSingle(K key, V value)
Set the key's value to be a one item list consisting of the supplied value. Any existing values will be replaced.- Parameters:
key
- the keyvalue
- the single value of the key
-
add
void add(K key, V value)
Add a value to the current list of values for the supplied key.- Parameters:
key
- the keyvalue
- the value to be added.
-
getFirst
V getFirst(K key)
A shortcut to get the first value of the supplied key.- Parameters:
key
- the key- Returns:
- the first value for the specified key or null if the key is not in the map.
-
addAll
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 aNullPointerException
if the supplied array of values isnull
.- Parameters:
key
- the key.newValues
- the values to be added.- Throws:
NullPointerException
- if the supplied array of new values isnull
.- Since:
- 2.0
-
addAll
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 aNullPointerException
if the supplied array of values isnull
.- Parameters:
key
- the key.valueList
- the list of values to be added.- Throws:
NullPointerException
- if the supplied value list isnull
.- Since:
- 2.0
-
addFirst
void addFirst(K key, V value)
Add a value to the first position in the current list of values for the supplied key.- Parameters:
key
- the keyvalue
- the value to be added.- Since:
- 2.0
-
equalsIgnoreValueOrder
boolean equalsIgnoreValueOrder(MultivaluedMap<K,V> otherMap)
Compare the specified map with this map for equality modulo the order of values for each key. Specifically, the values associated with each key are compared as if they were ordered lists.- Parameters:
otherMap
- map to be compared to this one.- Returns:
- true if the maps are equal modulo value ordering.
- Since:
- 2.0
