| Modifier and Type | Method and Description |
|---|---|
void |
clear()
Removes all associations from this function (optional operation).
|
boolean |
containsKey(double k) |
boolean |
containsKey(Object ok)
Returns true if this function contains a mapping for the specified key.
|
int |
defaultReturnValue()
Gets the default return value.
|
void |
defaultReturnValue(int defRetValue)
Sets the default return value.
|
int |
get(double k)
Returns the value to which the given key is mapped.
|
Integer |
get(Object k)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
int |
put(double k,
int v)
Adds a pair to the map.
|
Integer |
put(Double k,
Integer v)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
int |
remove(double k)
Removes the mapping with the given key.
|
Integer |
remove(Object k)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
int |
size()
Returns the intended number of keys in this function, or -1 if no such number exists.

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.
