public abstract class AbstractFloat2LongFunction extends Object implements Float2LongFunction, 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.
|
long |
defaultReturnValue()
Gets the default return value.
|
void |
defaultReturnValue(long rv)
Sets the default return value.
|
Long |
get(Object ok)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
long |
put(float key,
long value)
Adds a pair to the map.
|
Long |
put(Float ok,
Long ov)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
long |
remove(float key)
Removes the mapping with the given key.
|
Long |
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.
