  - getNoEntryValue
```
char getNoEntryValue()
```
    Returns the value that will be returned from get(java.lang.Object) or put(K, char) if no entry exists for a given key. The default value is generally zero, but can be configured during construction of the collection.
    
    Returns:
    
    the value that represents a null value in this collection.
  - size
```
int 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:
    
    the number of key-value mappings in this map
  - isEmpty
```
boolean isEmpty()
```
    Returns true if this map contains no key-value mappings.
    
    Returns:
    
    true if this map contains no key-value mappings
  - containsKey
```
boolean containsKey(Object key)
```
    Checks for the present of key in the keys of the map.
  - containsValue
```
boolean containsValue(char value)
```
    Checks for the presence of val in the values of the map.
  - get
```
char get(Object key)
```
    Retrieves the value for key.
    
    Returns:
    
    the previous value associated with key, or the "no entry" value if none was found (see getNoEntryValue()).
  - put
```
char put(K key,
         char value)
```
    Inserts a key/value pair into the map.
    
    Returns:
    
    the previous value associated with key, or the "no entry" value if none was found (see getNoEntryValue()).
  - putIfAbsent
```
char putIfAbsent(K key,
                 char value)
```
    Inserts a key/value pair into the map if the specified key is not already associated with a value.
    
    Parameters:
    
    key - key with which the specified value is to be associated
    
    value - an char value to be associated with the specified key
    
    Returns:
    
    the previous value associated with key, or the "no entry" value if none was found (see getNoEntryValue()).

    Parameters:
    
    key - an #k# value
    
    Returns:
    
    the previous value associated with key, or the "no entry" value if none was found (see getNoEntryValue()).
  - putAll
```
void putAll(Map<? extends K,? extends Character> m)
```
    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.
    
    Parameters:
    
    m - mappings to be stored in this map
    
    Throws:
    
    UnsupportedOperationException - if the putAll operation is not supported by this map
    
    ClassCastException - if the class of a key or value in the specified map prevents it from being stored in this map
    
    NullPointerException - if the specified map is null, or if this map does not permit null keys or values, and the specified map contains null keys or values
    
    IllegalArgumentException - if some property of a key or value in the specified map prevents it from being stored in this map
  - putAll
```
void putAll(TObjectCharMap<? extends K> map)
```
    Put all the entries from the given map into this map.
    
    Parameters:
    
    map - The map from which entries will be obtained to put into this map.
  - clear
```
void clear()
```
    Removes all of the mappings from this map (optional operation). The map will be empty after this call returns.
    
    Throws:
    
    UnsupportedOperationException - if the clear operation is not supported by this map
  - keySet
```
Set<K> keySet()
```
    Returns a Set view of the keys 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), 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:
    
    a set view of the keys contained in this map
  - keys
```
Object[] keys()
```
    Returns a copy of the keys of the map as an array. Changes to the array of keys will not be reflected in the map nor vice-versa.
    
    Returns:
    
    a copy of the keys of the map as an array.
  - keys
```
K[] keys(K[] array)
```
    Returns a copy of the keys of the map as an array. Changes to the array of keys will not be reflected in the map nor vice-versa.
    
    Parameters:
    
    array - the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same type is allocated for this purpose.
    
    Returns:
    
    the keys of the map as an array.
  - valueCollection
```
TCharCollection valueCollection()
```
    Returns a TCharCollection 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 TCharIterator.remove, TCharCollection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.
    
    Returns:
    
    a collection view of the values contained in this map
  - values
```
char[] values()
```
    Returns the values of the map as an array of char values. Changes to the array of values will not be reflected in the map nor vice-versa.

    the values of the map as an array of char values.
  - values
```
char[] values(char[] array)
```
    Returns the values of the map using an existing array. Changes to the array of values will not be reflected in the map nor vice-versa.
    
    Parameters:
    
    array - the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same type is allocated for this purpose.

    Returns:
    
    a TObjectCharIterator with access to this map's keys and values.
  - increment
```

```
    Increments the primitive value mapped to key by 1
    
    Parameters:
    
    key - the key of the value to increment
    
    Returns:
    
    true if a mapping was found and modified.
  - adjustValue
```
boolean adjustValue(K key,
                    char amount)
```
    Adds an amount to the primitive value mapped to key. If the key does not exist, the map is not modified (key-value is not inserted).
    
    Parameters:
    
    key - the key of the value to increment
    
    amount - the amount to add to the value; may be positive, zero, or negative

    true if a mapping was found and modified
    
    See Also:
    
    adjustOrPutValue(Object, char, char)
  - adjustOrPutValue
```
char adjustOrPutValue(K key,
                      char adjust_amount,
                      char put_amount)
```
    Adds an amount to the primitive value mapped to the key if the key is present in the map. Otherwise, the put_amount is put in the map.
    
    Parameters:
    
    key - the key of the value to increment
    
    adjust_amount - the amount to add to the value; may be positive, zero, or negative
    
    put_amount - the value put into the map if the key is not present
    
    Returns:
    
    the value present in the map after the adjustment or put operation
  - forEachKey
```
boolean forEachKey(TObjectProcedure<? super K> procedure)
```
    Executes procedure for each key in the map.
    
    Parameters:
    
    procedure - a TObjectProcedure value
    
    Returns:
    
    false if the loop over the keys terminated because the procedure returned false for some key.
  - forEachValue
```
boolean forEachValue(TCharProcedure procedure)
```
    Executes procedure for each value in the map.
    
    Parameters:
    
    procedure - a TCharProcedure value
    
    Returns:
    
    false if the loop over the values terminated because the procedure returned false for some value.
  - forEachEntry
```
boolean forEachEntry(TObjectCharProcedure<? super K> procedure)
```
    Executes procedure for each key/value entry in the map.
    
    Parameters:
    
    procedure - a TOObjectCharProcedure value
    
    Returns:
    
    false if the loop over the entries terminated because the procedure returned false for some entry.
  - transformValues
```
void transformValues(TCharFunction function)
```
    Transform the values in this map using function.
    
    Parameters:
    
    function - a TCharFunction value
  - retainEntries
```
boolean retainEntries(TObjectCharProcedure<? super K> procedure)
```
    Retains only those entries in the map for which the procedure returns a true value.
    
    Parameters:
    
    procedure - determines which entries to keep
    
    Returns:
    
    true if the map was modified.
  - equals
```
boolean equals(Object o)
```
    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.
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    o - object to be compared for equality with this map
    
    Returns:
    
    true if the specified object is equal to this map
  - hashCode
```
int 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().
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    the hash code value for this map
    
    See Also:
    
    Object.equals(Object), equals(Object)
