public abstract class AbstractDouble2CharFunction extends Object implements Double2CharFunction, 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)
Deprecated.
Please use the corresponding type-specific method instead.
|
char |
put(double key,
char value)
Adds a pair to the map.
|
Character |
put(Double ok,
Character ov)
Deprecated.
Please use the corresponding type-specific method instead.
|
char |
remove(double key)
Removes the mapping with the given key.
|
Character |
remove(Object ok)
Deprecated.
Please use the corresponding type-specific method instead.

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.
