public abstract class AbstractChar2CharFunction extends Object implements Char2CharFunction, Serializable
Optional operations just throw an UnsupportedOperationException. Generic versions of accessors delegate to
the corresponding type-specific counterparts following the interface rules
(they take care of returning null on a missing key).
This class handles directly a default return
value (including methods to access
it). Instances of classes inheriting from this class have just to return
defRetValue to denote lack of a key in type-specific methods. The value
is serialized.
Implementing subclasses have just to provide type-specific get(),
type-specific containsKey(), and size() methods.
| Modifier and Type | Method and Description |
|---|---|
void |
clear()
Removes all associations from this function (optional operation).
|
boolean |
containsKey(Object ok)
Returns true if this function contains a mapping for the specified key.
|
char |
defaultReturnValue()
Gets the default return value.
|
void |
defaultReturnValue(char rv)
Sets the default return value.
|
Character |
get(Object ok)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
Character |
put(Character ok,
Character ov)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
char |
put(char key,
char value)
Adds a pair to the map.
|
char |
remove(char key)
Removes the mapping with the given key.
|
Character |
remove(Object ok)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |

This method must check whether the provided key is in the map using containsKey(). Thus,
it probes the map twice. Implementors of subclasses should override it with a more efficient method.
