Method Detail

size

public int size()

Description copied from interface: Function

Returns the intended number of keys in this function, or -1 if no such number exists.

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.

Specified by:

size in interface Function<K,Float>

Specified by:

size in interface Map<K,Float>

Overrides:

size in class Reference2FloatFunctions.SynchronizedFunction<K>

Returns:

the intended number of keys in this function, or -1 if that number is not available.

containsKey

public boolean containsKey(Object k)

Description copied from interface: Function

Returns true if this function contains a mapping for the specified key.

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

Specified by:

containsKey in interface Function<K,Float>

Specified by:

containsKey in interface Map<K,Float>

Overrides:

containsKey in class Reference2FloatFunctions.SynchronizedFunction<K>

Parameters:

k - the key.

Returns:

true if this function associates a value to key.

See Also:

Map.containsKey(Object)

containsValue

public boolean containsValue(float v)

Specified by:

containsValue in interface Reference2FloatMap<K>

See Also:

Map.containsValue(Object)

defaultReturnValue

public float defaultReturnValue()

Description copied from interface: Reference2FloatFunction

Gets the default return value.

Specified by:

defaultReturnValue in interface Reference2FloatFunction<K>

Overrides:

defaultReturnValue in class Reference2FloatFunctions.SynchronizedFunction<K>

Returns:

the current default return value.

defaultReturnValue

public void defaultReturnValue(float defRetValue)

Description copied from interface: Reference2FloatFunction

Sets the default return value. This value must be returned by type-specific versions of get(), put() and remove() to denote that the map does not contain the specified key. It must be 0/false/null by default.

Specified by:

defaultReturnValue in interface Reference2FloatFunction<K>

Overrides:

defaultReturnValue in class Reference2FloatFunctions.SynchronizedFunction<K>

Parameters:

defRetValue - the new default return value.

See Also:

Reference2FloatFunction.defaultReturnValue()

put

public float put(K k,
        float v)

Description copied from interface: Reference2FloatFunction

Adds a pair to the map.

Specified by:

put in interface Reference2FloatFunction<K>

Overrides:

put in class Reference2FloatFunctions.SynchronizedFunction<K>

Parameters:

k - the key.

v - the value.

Returns:

the old value, or the default return value if no value was present for the given key.

See Also:

Function.put(Object,Object)

putAll

public void putAll(Map<? extends K,? extends Float> m)

Specified by:

putAll in interface Map<K,Float>

reference2FloatEntrySet

public ObjectSet<Reference2FloatMap.Entry<K>> reference2FloatEntrySet()

Description copied from interface: Reference2FloatMap

Returns a type-specific set view of the mappings contained in this map.

This method is necessary because there is no inheritance along type parameters: it is thus impossible to strengthen Reference2FloatMap.entrySet() so that it returns an ObjectSet of objects of type Map.Entry (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

reference2FloatEntrySet in interface Reference2FloatMap<K>

Returns:

a type-specific set view of the mappings contained in this map.

See Also:

Reference2FloatMap.entrySet()

keySet

public ReferenceSet<K> keySet()

Description copied from interface: Reference2FloatMap

Returns a set view of the keys contained in this map.

Note that this specification strengthens the one given in Map.keySet().

Specified by:

keySet in interface Reference2FloatMap<K>

Specified by:

keySet in interface Map<K,Float>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public FloatCollection values()

Description copied from interface: Reference2FloatMap

Returns a set view of the values contained in this map.

Note that this specification strengthens the one given in Map.values().

Specified by:

values in interface Reference2FloatMap<K>

Specified by:

values in interface Map<K,Float>

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

clear

public void clear()

Description copied from interface: Function

Removes all associations from this function (optional operation).

Specified by:

clear in interface Function<K,Float>

Specified by:

clear in interface Map<K,Float>

Overrides:

clear in class Reference2FloatFunctions.SynchronizedFunction<K>

See Also:

Map.clear()

toString

public String toString()

Overrides:

toString in class Reference2FloatFunctions.SynchronizedFunction<K>

put

public Float put(K k,
        Float v)

Description copied from class: AbstractReference2FloatFunction

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.

Specified by:

put in interface Function<K,Float>

Specified by:

put in interface Map<K,Float>

Overrides:

put in class Reference2FloatFunctions.SynchronizedFunction<K>

Parameters:

k - the key.

v - the value.

Returns:

the old value, or null if no value was present for the given key.

See Also:

Map.put(Object,Object)

containsValue

public boolean containsValue(Object ov)

Specified by:

containsValue in interface Map<K,Float>

removeFloat

public float removeFloat(Object k)

Description copied from interface: Reference2FloatFunction

Removes the mapping with the given key.

Specified by:

removeFloat in interface Reference2FloatFunction<K>

Overrides:

removeFloat in class Reference2FloatFunctions.SynchronizedFunction<K>

Returns:

the old value, or the default return value if no value was present for the given key.

See Also:

Function.remove(Object)

getFloat

public float getFloat(Object k)

Description copied from interface: Reference2FloatFunction

Returns the value to which the given key is mapped.

Specified by:

getFloat in interface Reference2FloatFunction<K>

Overrides:

getFloat in class Reference2FloatFunctions.SynchronizedFunction<K>

Parameters:

k - the key.

Returns:

the corresponding value, or the default return value if no value was present for the given key.

Function.get(Object)

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Map<K,Float>

entrySet

public ObjectSet<Map.Entry<K,Float>> entrySet()

Description copied from interface: Reference2FloatMap

Returns a set view of the mappings contained in this map.

Note that this specification strengthens the one given in Map.entrySet().

Specified by:

entrySet in interface Reference2FloatMap<K>

Specified by:

entrySet in interface Map<K,Float>

Returns:

a set view of the mappings contained in this map.
