public static class Byte2ObjectFunctions.SynchronizedFunction<V> extends AbstractByte2ObjectFunction<V> implements java.io.Serializable
Modifier and Type | Method and Description |
---|---|
void |
clear()
Removes all associations from this function (optional operation).
|
boolean |
containsKey(byte k) |
boolean |
containsKey(java.lang.Object ok)
Returns true if this function contains a mapping for the specified key.
|
V |
defaultReturnValue()
Gets the default return value.
|
void |
defaultReturnValue(V defRetValue)
Sets the default return value.
|
V |
get(byte k)
Returns the value to which the given key is mapped.
|
V |
get(java.lang.Object k)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
V |
put(byte k,
V v)
Adds a pair to the map.
|
V |
put(java.lang.Byte k,
V v)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
V |
remove(byte k)
Removes the mapping with the given key.
|
V |
remove(java.lang.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.
|
java.lang.String |
toString() |
public int size()
Function
Most function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible.

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.
