    public static class Float2FloatMaps.Singleton
extends Float2FloatFunctions.Singleton
implements Float2FloatMap, java.io.Serializable, java.lang.Cloneable
    An immutable class representing a type-specific singleton map.

    This class may be useful to implement your own in case you subclass a type-specific map.

    • Method Detail

      • containsValue

        public boolean containsValue​(float v)
        Description copied from interface: Float2FloatMap
        Returns true if this map maps one or more keys to the specified value.
        Specified by:
        containsValue in interface Float2FloatMap
        See Also:
        Map.containsValue(Object)

      • containsValue

        @Deprecated
public boolean containsValue​(java.lang.Object ov)
        Deprecated.
        Please use the corresponding type-specific method instead.
        Specified by:
        containsValue in interface Float2FloatMap
        Specified by:
        containsValue in interface java.util.Map<java.lang.Float,​java.lang.Float>

      • putAll

        public void putAll​(java.util.Map<? extends java.lang.Float,​? extends java.lang.Float> m)
        Specified by:
        putAll in interface java.util.Map<java.lang.Float,​java.lang.Float>

      • float2FloatEntrySet

        public ObjectSet<Float2FloatMap.Entry> float2FloatEntrySet()
        Description copied from interface: Float2FloatMap
        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:
        float2FloatEntrySet in interface Float2FloatMap
        Returns:
        a type-specific set view of the mappings contained in this map.
        See Also:
        Map.entrySet()

      • entrySet

        @Deprecated
public ObjectSet<java.util.Map.Entry<java.lang.Float,​java.lang.Float>> entrySet()
        Deprecated.
        Please use the corresponding type-specific method instead.
        Returns a set view of the mappings contained in this map.
        Specified by:
        entrySet in interface Float2FloatMap
        Specified by:
        entrySet in interface java.util.Map<java.lang.Float,​java.lang.Float>
        Returns:
        a set view of the mappings contained in this map.

        Specified by:
        keySet in interface java.util.Map<java.lang.Float,​java.lang.Float>
        Returns:
        a set view of the keys contained in this map.

        Specified by:
        values in interface Float2FloatMap
        Specified by:
        values in interface java.util.Map<java.lang.Float,​java.lang.Float>
        Returns:
        a set view of the values contained in this map.
