        putSingle in interface MultivaluedMap<String,​V>
        Parameters:
        key - the key
        value - the single value of the key
      • add

        public void add​(String key,
                        V value)
        Description copied from interface: MultivaluedMap
        Add a value to the current list of values for the supplied key.
        Specified by:
        add in interface MultivaluedMap<String,​V>
        Parameters:
        key - the key
        value - the value to be added.
      • getFirst

        public V getFirst​(String key)
        Description copied from interface: MultivaluedMap
        A shortcut to get the first value of the supplied key.
        Specified by:
        getFirst in interface MultivaluedMap<String,​V>
        Parameters:
        key - the key
        Returns:
        the first value for the specified key or null if the key is not in the map.
      • addAll

        public void addAll​(String key,
                           V... newValues)
        Description copied from interface: MultivaluedMap
        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.
        Specified by:
        addAll in interface MultivaluedMap<String,​V>
        Parameters:
        key - the key.
        newValues - the values to be added.
      • addAll

        public void addAll​(String key,
                           List<V> valueList)
        Description copied from interface: MultivaluedMap
        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.
        Specified by:
        addAll in interface MultivaluedMap<String,​V>
        Parameters:
        key - the key.
        valueList - the list of values to be added.
      • addFirst

        public void addFirst​(String key,
                             V value)
        Description copied from interface: MultivaluedMap
        Add a value to the first position in the current list of values for the supplied key.
        Specified by:
        addFirst in interface MultivaluedMap<String,​V>
        Parameters:
        key - the key
        value - the value to be added.
      • equalsIgnoreValueOrder

        public boolean equalsIgnoreValueOrder​(MultivaluedMap<String,​V> otherMap)
        Description copied from interface: MultivaluedMap
        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.
        Specified by:
        equalsIgnoreValueOrder in interface MultivaluedMap<String,​V>
        Parameters:
        otherMap - map to be compared to this one.
        Returns:
        true if the maps are equal modulo value ordering.
      • setGuard

        public void setGuard​(String key)
        Observe changes of a value represented by the key.
        Parameters:
        key - the key values to observe
      • getGuards

        public Set<String> getGuards()
        Get all the guarded keys
        Returns:
        a Set of keys guarded.
      • isObservedAndReset

        public boolean isObservedAndReset​(String key)
        Return true when the value represented by the key has changed. Resets any observation - the operation is not idempotent.
        Parameters:
        key - the Key observed.
        Returns:
        whether the value represented by the key has changed.
