the key

value:V

the value to be added.

Annotations
@Override
addFirstNullback to summary
protected void addFirstNull(final 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.

values:List<V>

value list where the null value addition is being requested.

Annotations
@SuppressWarnings:UnusedParameters
addNullback to summary
protected void addNull(final 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.

clearback to summary
public void clear()

Implements java.util.Map.clear.

Doc from java.util.Map.clear.

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

Annotations
@Override
containsKeyback to summary
public boolean containsKey(final Object key)

Implements java.util.Map.containsKey.

Doc from java.util.Map.containsKey.

Returns true if this map contains a mapping for the specified key. More formally, returns true if and only if this map contains a mapping for a key k such that Objects.equals(key, k). (There can be at most one such mapping.)

Parameters
key:Object

key whose presence in this map is to be tested

Returns:boolean

true if this map contains a mapping for the specified key

Annotations
@Override
containsValueback to summary
public boolean containsValue(final Object value)

Implements java.util.Map.containsValue.

Doc from java.util.Map.containsValue.

Returns true if this map maps one or more keys to the specified value. More formally, returns true if and only if this map contains at least one mapping to a value v such that Objects.equals(value, v). This operation will probably require time linear in the map size for most implementations of the Map interface.

Parameters
value:Object

value whose presence in this map is to be tested

Returns:boolean

true if this map maps one or more keys to the specified value

Annotations
@Override
entrySetback to summary
public Set<Map.Entry<K, List<V>>> entrySet()

Implements java.util.Map.entrySet.

Doc from java.util.Map.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<Map.Entry<K, List<V>>>

a set view of the mappings contained in this map

Annotations
@Override
equalsback to summary
public boolean equals(final Object o)

Overrides java.lang.Object.equals.

Implements java.util.Map.equals.

Doc from java.util.Map.equals.

Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings. More formally, two maps m1 and m2 represent the same mappings if m1.entrySet().equals(m2.entrySet()). This ensures that the equals method works properly across different implementations of the Map interface.

This implementation delegates the method call to to the the underlying [key, multi-value] store.

Parameters
o:Object

object to be compared for equality with this map

Returns:boolean

true if the specified object is equal to the underlying [key, multi-value] store, false otherwise.

Annotations

@SuppressWarnings:EqualsWhichDoesntCheckParameterClass
equalsIgnoreValueOrderback to summary
public boolean equalsIgnoreValueOrder(final MultivaluedMap<K, V> omap)

Implements jakarta.ws.rs.core.MultivaluedMap.equalsIgnoreValueOrder.

Doc from jakarta.ws.rs.core.MultivaluedMap.equalsIgnoreValueOrder.

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
omap:MultivaluedMap<K, V>

map to be compared to this one.

Returns:boolean

true if the maps are equal modulo value ordering.

Annotations
@Override
getback to summary
public List<V> get(final Object key)

Implements java.util.Map.get.

Doc from java.util.Map.get.

Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.

More formally, if this map contains a mapping from a key k to a value v such that Objects.equals(key, k), then this method returns v; otherwise it returns null. (There can be at most one such mapping.)

If this map permits null values, then a return value of null does not necessarily indicate that the map contains no mapping for the key; it's also possible that the map explicitly maps the key to null. The containsKey operation may be used to distinguish these two cases.

Parameters
key:Object

the key whose associated value is to be returned

Returns:List<V>

the value to which the specified key is mapped, or null if this map contains no mapping for the key

Annotations
@Override
getFirstback to summary
public final V getFirst(final K key)

Implements jakarta.ws.rs.core.MultivaluedMap.getFirst.

Doc from jakarta.ws.rs.core.MultivaluedMap.getFirst.

A shortcut to get the first value of the supplied key.

Parameters
key:K

the key

Returns:V

the first value for the specified key or null if the key is not in the map.

Annotations
@Override
getValuesback to summary
protected final List<V> getValues(final 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:K

the key.

Returns:List<V>

value list registered with the key. The method is guaranteed to never return null.

hashCodeback to summary
public int hashCode()

Overrides java.lang.Object.hashCode.

Implements java.util.Map.hashCode.

Doc from java.util.Map.hashCode.

Returns the hash code value for this map. The hash code of a map is defined to be the sum of the hash codes of each entry in the map's entrySet() view. This ensures that m1.equals(m2) implies that m1.hashCode()==m2.hashCode() for any two maps m1 and m2, as required by the general contract of Object#hashCode.

This implementation delegates the method call to to the the underlying [key, multi-value] store.

Returns:int

a hash code value for the underlying [key, multi-value] store.

Annotations
@Override
isEmptyback to summary
public boolean isEmpty()

Implements java.util.Map.isEmpty.

Doc from java.util.Map.isEmpty.

Returns true if this map contains no key-value mappings.

Returns:boolean

true if this map contains no key-value mappings

Annotations
@Override
keySetback to summary
public Set<K> keySet()

Implements java.util.Map.keySet.

Doc from java.util.Map.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<K>

a set view of the keys contained in this map

Annotations
@Override
putback to summary
public List<V> put(final K key, final List<V> value)

Implements java.util.Map.put.

Doc from java.util.Map.put.

Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value. (A map m is said to contain a mapping for a key k if and only if m.containsKey(k) would return true.)

Parameters
key:K

key with which the specified value is to be associated

value:List<V>

value to be associated with the specified key

Returns:List<V>

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, if the implementation supports null values.)

Annotations
@Override
putAllback to summary
public void putAll(final Map<? extends K, ? extends List<V>> m)

Implements java.util.Map.putAll.

Doc from java.util.Map.putAll.

Copies all of the mappings from the specified map to this map (optional operation). The effect of this call is equivalent to that of calling put(k, v) on this map once for each mapping from key k to value v in the specified map. The behavior of this operation is undefined if the specified map is modified while the operation is in progress. If the specified map has a defined encounter order, processing of its mappings generally occurs in that order.

Parameters
m:Map<? extends K, ? extends List<V>>

mappings to be stored in this map

Annotations
@Override
putSingleback to summary
public final void putSingle(final K key, final V value)

Implements jakarta.ws.rs.core.MultivaluedMap.putSingle.

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.
Parameters
key:K

the key

value:V

the single value of the key. If the value is null it will be ignored.

Annotations
@Override
removeback to summary
public List<V> remove(final Object key)

Implements java.util.Map.remove.

Doc from java.util.Map.remove.

Removes the mapping for a key from this map if it is present (optional operation). More formally, if this map contains a mapping from key k to value v such that Objects.equals(key, k), that mapping is removed. (The map can contain at most one such mapping.)

Returns the value to which this map previously associated the key, or null if the map contained no mapping for the key.

If this map permits null values, then a return value of null does not necessarily indicate that the map contained no mapping for the key; it's also possible that the map explicitly mapped the key to null.

The map will not contain a mapping for the specified key once the call returns.

Parameters
key:Object

key whose mapping is to be removed from the map

Returns:List<V>

the previous value associated with key, or null if there was no mapping for key.

Annotations
@Override
sizeback to summary
public int size()

Implements java.util.Map.size.

Doc from java.util.Map.size.

Returns the number of key-value mappings in this map. If the map contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

Returns:int

the number of key-value mappings in this map

Annotations
@Override
toStringback to summary
public String toString()

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object.

Returns:String

a string representation of the object.

Annotations
@Override
valuesback to summary
public Collection<List<V>> values()

Implements java.util.Map.values.

Doc from java.util.Map.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<List<V>>

a collection view of the values contained in this map
