Modifier and Type | Method and Description |
---|---|
void |
clear()
Removes all associations from this function (optional operation).
|
boolean |
containsKey(java.lang.Object k)
Returns true if this function contains a mapping for the specified key.
|
char |
defaultReturnValue()
Gets the default return value.
|
void |
defaultReturnValue(char defRetValue)
Sets the default return value.
|
java.lang.Character |
get(java.lang.Object k)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
char |
getChar(java.lang.Object k)
Returns the value to which the given key is mapped.
|
char |
put(K k,
char v)
Adds a pair to the map.
|
java.lang.Character |
put(K k,
java.lang.Character v)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
java.lang.Character |
remove(java.lang.Object k)
Delegates to the corresponding type-specific method, taking care of returning
null on a missing key. |
char |
removeChar(java.lang.Object k)
Removes the mapping with the given 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.
public boolean containsKey(java.lang.Object k)

Note that for some kind of functions (e.g., hashes) this method will always return true.

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.
