public Set<Map.Entry<Character, 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<Character, V>> a set view of the mappings contained in this map Annotations @Override

Doc from io.netty.util.collection.CharObjectMap.get.

public 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`. 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 V get(Object key)

public V put(Character key, 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:Character 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.) Annotations @Override
