Method Details

containsValue

public boolean containsValue(boolean v)

Description copied from interface: Float2BooleanMap

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

Specified by:

containsValue in interface Float2BooleanMap

See Also:

Map.containsValue(Object)

getOrDefault

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

Deprecated.

Description copied from interface: Float2BooleanMap

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

This default implementation just delegates to the corresponding Map method.

Specified by:

getOrDefault in interface Float2BooleanFunction

Specified by:

getOrDefault in interface Float2BooleanMap

Specified by:

getOrDefault in interface Function<Float,Boolean>

Specified by:

getOrDefault in interface Map<Float,Boolean>

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 boolean getOrDefault(float key,
boolean defaultValue)

Description copied from interface: Float2BooleanFunction

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

Specified by:

getOrDefault in interface Float2BooleanFunction

Specified by:

getOrDefault in interface Float2BooleanMap

Overrides:

getOrDefault in class Float2BooleanFunctions.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)

containsValue

@Deprecated
public boolean containsValue(Object ov)

Deprecated.

Please use the corresponding type-specific method instead.

Specified by:

containsValue in interface Float2BooleanMap

Specified by:

containsValue in interface Map<Float,Boolean>

putAll

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

Specified by:

putAll in interface Map<Float,Boolean>

float2BooleanEntrySet

public ObjectSet<Float2BooleanMap.Entry> float2BooleanEntrySet()

Description copied from interface: Float2BooleanMap

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:

float2BooleanEntrySet in interface Float2BooleanMap

Returns:

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

See Also:

Map.entrySet()

keySet

public FloatSet keySet()

Description copied from interface: Float2BooleanMap

Specified by:

keySet in interface Float2BooleanMap

Specified by:

keySet in interface Map<Float,Boolean>

Returns:

a set view of the keys contained in this map.

See Also:

Map.keySet()

values

public BooleanCollection values()

Description copied from interface: Float2BooleanMap

Specified by:

values in interface Float2BooleanMap

Specified by:

values in interface Map<Float,Boolean>

Returns:

a set view of the values contained in this map.

See Also:

Map.values()

forEach

public void forEach(BiConsumer<? super Float,? super Boolean> consumer)

Specified by:

forEach in interface Float2BooleanMap

Specified by:

forEach in interface Map<Float,Boolean>

clone

public Object clone()

Overrides:

clone in class Float2BooleanFunctions.EmptyFunction

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface Map<Float,Boolean>

hashCode

public int hashCode()

Specified by:

hashCode in interface Map<Float,Boolean>

Overrides:

hashCode in class Float2BooleanFunctions.EmptyFunction

equals

public boolean equals(Object o)

Specified by:

equals in interface Map<Float,Boolean>

Overrides:

equals in class Float2BooleanFunctions.EmptyFunction

toString

public String toString()

Overrides:

toString in class Float2BooleanFunctions.EmptyFunction
