- Method Detail
  - get
```
V get(char key)
```
    Gets the value in the map with the specified key.
    
    Parameters:
    
    key - the key whose associated value is to be returned.
    
    Returns:
    
    the value or null if the key was not found in the map.
  - put
```
V put(char key,
      V value)
```
    Puts the given entry into the map.
    
    Parameters:
    
    key - the key of the entry.
    
    value - the value of the entry.
    
    Returns:
    
    the previous value for this key or null if there was no previous mapping.
  - remove
```
V remove(char key)
```
    Removes the entry with the specified key.
    
    Parameters:
    
    key - the key for the entry to be removed from this map.
    
    Returns:
    
    the previous value for the key, or null if there was no mapping.
  - entries
```
Iterable<CharObjectMap.PrimitiveEntry<V>> entries()
```
    Gets an iterable to traverse over the primitive entries contained in this map. As an optimization, the CharObjectMap.PrimitiveEntrys returned by the Iterator may change as the Iterator progresses. The caller should not rely on CharObjectMap.PrimitiveEntry key/value stability.
  - containsKey
```
boolean containsKey(char key)
```
    Indicates whether or not this map contains a value for the specified key.
