get	back to summary
public List<V> get(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`.

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

public List<V> remove(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.

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

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

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 Annotations @Override
