entrySet	back to summary
public Set<Map.Entry<K, 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.

equals back to summary

equals	back to summary
public final boolean equals(final Object arrayHashMap) 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. Parameters arrayHashMap:Object object to be compared for equality with this map Returns:boolean `true` if the specified object is equal to this map Annotations @Override

public final boolean equals(final Object arrayHashMap)

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.

Parameters

arrayHashMap:Object: object to be compared for equality with this map

Returns:boolean

true if the specified object is equal to this map

get back to summary

get	back to summary
public final 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:V the value to which the specified key is mapped, or `null` if this map contains no mapping for the key Annotations @Override

public final V get(final Object key)

Implements 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.

hashCode	back to summary
public final 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`. Returns:int the hash code value for this map Annotations @Override

put back to summary

put	back to summary
public final V put(final K key, final V value) throws NullPointerException 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`.) This is an O(1) operation, in case the key does not exist, otherwise O(n). Parameters key:K key with which the specified value is to be associated value:V value to be associated with the specified key Returns: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.)

public final V put(final K key, final V value) throws NullPointerException

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.)

This is an O(1) operation, in case the key does not exist, otherwise O(n).

Parameters

key:K: key with which the specified value is to be associated
value:V: value to be associated with the specified key

Returns: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.)

public void putAll(final Map<? extends K, ? extends 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.
