containsKey(char key)
Returns true if the receiver contains the specified key.
|
boolean |
containsValue(T value)
Returns true if the receiver contains the specified value.

|
abstract boolean |
forEachKey(CharProcedure procedure)

|
boolean |
forEachPair(CharObjectProcedure<T> procedure)
Applies a procedure to each (key,value) pair of the receiver, if any.
|
abstract T |
get(char key)
Returns the value associated with the specified key.
|
int |
hashCode() |
CharArrayList |
keys()
Returns a list filled with all keys contained in the receiver.
|
void |
keys(CharArrayList list)
Fills all keys contained in the receiver into the specified list.
|
void |
keysSortedByValue(CharArrayList keyList)
Fills all keys sorted ascending by their associated value into the specified list.
|
void |
pairsMatching(CharObjectProcedure<T> condition,
CharArrayList keyList,
List<T> valueList)
Fills all pairs satisfying a given condition into the specified lists.
|
void |
pairsSortedByKey(CharArrayList keyList,
List<T> valueList)
Fills all keys and values sorted ascending by key into the specified lists.
|
void |
pairsSortedByValue(CharArrayList keyList,
List<T> valueList)
Fills all keys and values sorted ascending by value according to natural ordering into the specified lists.
|
abstract boolean |
put(char key,
T value)
Associates the given key with the given value.
|
abstract boolean |
removeKey(char key)
Removes the given key with its associated element from the receiver, if present.
|
String |
toString()
Returns a string representation of the receiver, containing the String representation of each key-value pair,
sorted ascending by key.
|
String |
toStringByValue()
Returns a string representation of the receiver, containing the String representation of each key-value pair,
sorted ascending by value, according to natural ordering.
|
List<T> |
values()

m1.forEachPair( new CharObjectProcedure() { public boolean apply(char key, Object value) { return m2.containsKey(key) && m2.get(key) == value; } } ) && m2.forEachPair( new CharObjectProcedure() { public boolean apply(char key, Object value) { return m1.containsKey(key) && m1.get(key) == value; } } );This implementation first checks if the specified object is this map; if so it returns true. Then, it checks if the specified object is a map whose size is identical to the size of this set; if not, it it returns false. If so, it applies the iteration as described above.

procedure
- the procedure to be applied. Stops iteration if the procedure returns false, otherwise
continues.public boolean forEachPair(CharObjectProcedure<T> procedure)

.procedure
- the procedure to be applied. Stops iteration if the procedure returns false, otherwise
continues.public abstract T get(char key)

whether the given key has a value associated or not, i.e. whether there exists an association
for the given key or not.key
- the key to be searched for.public CharArrayList keys()

list
- the list to be filled, can have any size.public void keysSortedByValue(CharArrayList keyList)
Example:
