Method Detail

containsValue

public boolean containsValue(byte v)

Specified by:

containsValue in interface Float2ByteMap

See Also:

Map.containsValue(Object)

putAll

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

Specified by:

putAll in interface Map<Float,Byte>

float2ByteEntrySet

public ObjectSet<Float2ByteMap.Entry> float2ByteEntrySet()

Description copied from interface: Float2ByteMap

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 Float2ByteMap.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:

float2ByteEntrySet in interface Float2ByteMap

Returns:

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

See Also:

Float2ByteMap.entrySet()

keySet

public FloatSet keySet()

Description copied from interface: Float2ByteMap

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 Float2ByteMap

Specified by:

keySet in interface Map<Float,Byte>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public ByteCollection values()

Description copied from interface: Float2ByteMap

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 Float2ByteMap

Specified by:

values in interface Map<Float,Byte>

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

containsValue

public boolean containsValue(Object ov)

Specified by:

containsValue in interface Map<Float,Byte>

clone

public Object clone()

Overrides:

clone in class Float2ByteFunctions.EmptyFunction

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Map<Float,Byte>

entrySet

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

Description copied from interface: Float2ByteMap

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 Float2ByteMap

Specified by:

entrySet in interface Map<Float,Byte>

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

hashCode

public int hashCode()

Specified by:

hashCode in interface Map<Float,Byte>

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Specified by:

equals in interface Map<Float,Byte>

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
