Method Detail

containsValue

public boolean containsValue(short v)

Description copied from interface: Float2ShortMap

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

Specified by:

containsValue in interface Float2ShortMap

See Also:

Map.containsValue(Object)

getOrDefault

@Deprecated
public java.lang.Short getOrDefault(java.lang.Object key,
                                                java.lang.Short defaultValue)

Deprecated.

Description copied from interface: Float2ShortMap

This default implementation just delegates to the corresponding Map method.

Specified by:

getOrDefault in interface it.unimi.dsi.fastutil.floats.Float2ShortFunction

Specified by:

getOrDefault in interface Float2ShortMap

Specified by:

getOrDefault in interface java.util.Map<java.lang.Float,java.lang.Short>

getOrDefault

public short getOrDefault(float key,
                          short defaultValue)

Description copied from interface: Float2ShortMap

Returns the value to which the specified key is mapped, or the defaultValue if this map contains no mapping for the key.

Specified by:

getOrDefault in interface it.unimi.dsi.fastutil.floats.Float2ShortFunction

Specified by:

getOrDefault in interface Float2ShortMap

Overrides:

getOrDefault in class Float2ShortFunctions.EmptyFunction

Parameters:

key - the key.

defaultValue - the default mapping of the key.

Returns:

the value to which the specified key is mapped, or the defaultValue if this map contains no mapping for the key.

See Also:

Map.getOrDefault(Object, Object)

containsValue

@Deprecated
public boolean containsValue(java.lang.Object ov)

Deprecated. Please use the corresponding type-specific method instead.

Specified by:

containsValue in interface Float2ShortMap

Specified by:

containsValue in interface java.util.Map<java.lang.Float,java.lang.Short>

putAll

public void putAll(java.util.Map<? extends java.lang.Float,? extends java.lang.Short> m)

Specified by:

putAll in interface java.util.Map<java.lang.Float,java.lang.Short>

float2ShortEntrySet

public it.unimi.dsi.fastutil.objects.ObjectSet<Float2ShortMap.Entry> float2ShortEntrySet()

Description copied from interface: Float2ShortMap

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:

float2ShortEntrySet in interface Float2ShortMap

Returns:

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

See Also:

Map.entrySet()

keySet

public it.unimi.dsi.fastutil.floats.FloatSet keySet()

Description copied from interface: Float2ShortMap

Specified by:

keySet in interface Float2ShortMap

Specified by:

keySet in interface java.util.Map<java.lang.Float,java.lang.Short>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public it.unimi.dsi.fastutil.shorts.ShortCollection values()

Description copied from interface: Float2ShortMap

Specified by:

values in interface Float2ShortMap

Specified by:

values in interface java.util.Map<java.lang.Float,java.lang.Short>

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

forEach

public void forEach(java.util.function.BiConsumer<? super java.lang.Float,? super java.lang.Short> consumer)

Specified by:

public int hashCode()

Specified by:

hashCode in interface java.util.Map<java.lang.Float,java.lang.Short>

Overrides:

hashCode in class Float2ShortFunctions.EmptyFunction
