public static class Int2BooleanFunctions.SynchronizedFunction extends AbstractInt2BooleanFunction implements Serializable
| Modifier and Type | Method and Description |
|---|---|
void |
clear()
Removes all associations from this function (optional operation).
|
boolean |
containsKey(int k) |
boolean |
containsKey(Object ok)
Returns true if this function contains a mapping for the specified key.
|
boolean |
defaultReturnValue()
Gets the default return value.
|
void |
defaultReturnValue(boolean defRetValue)
Sets the default return value.
|
boolean |
get(int k)
Returns the value to which the given key is mapped.
|
Boolean |
get(Object k)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
boolean |
put(int k,
boolean v)
Adds a pair to the map.
|
Boolean |
put(Integer k,
Boolean v)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
boolean |
remove(int k)
Removes the mapping with the given key.
|
Boolean |
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.
|
String |
toString() |
public int size()
FunctionMost function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible.

AbstractInt2BooleanFunctionnull 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.
