All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method and Description
`boolean`	`containsKey(K key)` Returns `true` if this map contains a mapping for `key`.
`V`	`get(K key)` Returns the value to which `key` is mapped, or `null` if this map contains no mapping for `key`.
`default V`	`get(K key, V defaultValue)` Returns the value to which `key` is mapped, or `defaultValue` if this map contains no mapping for `key`.
`UnmodifiableMapCursor<K,V>`	`getEntries()` Returns a `UnmodifiableMapCursor` view of the mappings contained in this map.
`default Equivalence`	`getEquivalenceStrategy()` Returns the strategy used to compare keys.
`Iterable<K>`	`getKeys()` Returns a `Iterable` view of the keys contained in this map.
`Iterable<V>`	`getValues()` Returns a `Iterable` view of the values contained in this map.
`boolean`	`isEmpty()` Returns `true` if this map contains no key-value mappings.
`int`	`size()` Returns the number of key-value mappings in this map.
