Method Details

containsValue

public boolean containsValue(float v)

Description copied from interface: Short2FloatMap

Returns true if this map maps one or more keys to the specified value.

Specified by:

containsValue in interface Short2FloatMap

See Also:

• Map.containsValue(Object)

getOrDefault

@Deprecated
public Float getOrDefault(Object key,
 Float defaultValue)

Deprecated.

Description copied from interface: Short2FloatFunction

Returns the value associated by this function to the specified key, or give the specified value if not present.

Specified by:

getOrDefault in interface Function<Short,Float>

Specified by:

getOrDefault in interface Map<Short,Float>

Specified by:

getOrDefault in interface Short2FloatFunction

Specified by:

getOrDefault in interface Short2FloatMap

Parameters:

key - the key.

defaultValue - the default value to return if not present.

Returns:

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

See Also:

• Map.getOrDefault(Object, Object)

getOrDefault

public float getOrDefault(short key,
 float defaultValue)

Description copied from interface: Short2FloatFunction

Returns the value associated by this function to the specified key, or give the specified value if not present.

Specified by:

getOrDefault in interface Short2FloatFunction

Specified by:

getOrDefault in interface Short2FloatMap

Overrides:

getOrDefault in class Short2FloatFunctions.EmptyFunction

Parameters:

key - the key.

defaultValue - the value to return if not present.

Returns:

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

See Also:

• Function.getOrDefault(Object, Object)

forEach

public void forEach(ShortFloatBiConsumer consumer)

Description copied from interface: Short2FloatMap

Performs the given action for each entry in this map until all entries have been processed or the action throws an exception.

This default implementation just delegates to forEach on the type-specific entry set, taking care of using fastForEach if available.

Specified by:

forEach in interface Short2FloatMap

See Also:

• Map.forEach(java.util.function.BiConsumer)

containsValue

@Deprecated
public boolean containsValue(Object ov)

Deprecated.

Please use the corresponding type-specific method instead.

Specified by:

containsValue in interface Map<Short,Float>

Specified by:

containsValue in interface Short2FloatMap

putAll

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

Specified by:

putAll in interface Map<Short,Float>

short2FloatEntrySet

public ObjectSet<Short2FloatMap.Entry> short2FloatEntrySet()

Description copied from interface: Short2FloatMap

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 Map.entrySet() so that it returns an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).

Specified by:

short2FloatEntrySet in interface Short2FloatMap

Returns:

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

See Also:

• Map.entrySet()

keySet

public ShortSet keySet()

Description copied from interface: Short2FloatMap

Specified by:

keySet in interface Map<Short,Float>

Specified by:

keySet in interface Short2FloatMap

Returns:

a set view of the keys contained in this map.

See Also:

• Map.keySet()

values

public FloatCollection values()

Description copied from interface: Short2FloatMap

Specified by:

values in interface Map<Short,Float>

Specified by:

values in interface Short2FloatMap

Returns:

a set view of the values contained in this map.

See Also:

• Map.values()

clone

public Object clone()

Overrides:

clone in class Short2FloatFunctions.EmptyFunction

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Map<Short,Float>

hashCode

public int hashCode()

Specified by:

hashCode in interface Map<Short,Float>

Overrides:

hashCode in class Short2FloatFunctions.EmptyFunction

equals

public boolean equals(Object o)

Specified by:

equals in interface Map<Short,Float>

Overrides:

equals in class Short2FloatFunctions.EmptyFunction

toString

public String toString()

Overrides:

toString in class Short2FloatFunctions.EmptyFunction
