Method Detail

containsValue

public boolean containsValue(boolean v)

Description copied from interface: Object2BooleanMap

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

Specified by:

containsValue in interface Object2BooleanMap<K>

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 Object2BooleanMap<K>

Specified by:

putAll

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

object2BooleanEntrySet

public ObjectSet<Object2BooleanMap.Entry<K>> object2BooleanEntrySet()

Description copied from interface: Object2BooleanMap

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:

object2BooleanEntrySet in interface Object2BooleanMap<K>

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<K,java.lang.Boolean>> entrySet()

Note that this specification strengthens the one given in Map.entrySet().

Specified by:

entrySet in interface Object2BooleanMap<K>

Specified by:

entrySet in interface java.util.Map<K,java.lang.Boolean>

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

keySet

public ObjectSet<K> keySet()

Description copied from interface: Object2BooleanMap

Note that this specification strengthens the one given in Map.keySet().

Specified by:

keySet in interface Object2BooleanMap<K>

getOrDefault

public boolean getOrDefault(java.lang.Object key,
                            boolean defaultValue)

Description copied from interface: Object2BooleanMap

                           boolean value)

public boolean computeBooleanIfAbsent(K key,
                                      java.util.function.Predicate<? super K> mappingFunction)

Description copied from interface: Object2BooleanMap

If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map.

Note that contrarily to the default computeIfAbsent(), it is not possible to not add a value for a given key, since the mappingFunction cannot return null. If such a behavior is needed, please use the corresponding nullable version.

Specified by:

computeBooleanIfAbsent in interface Object2BooleanMap<K>

Parameters:

key - key with which the specified value is to be associated.

mappingFunction - the function to compute a value.

Returns:

the current (existing or computed) value associated with the specified key.

See Also:

Map.computeIfAbsent(Object, java.util.function.Function)

computeBooleanIfAbsentPartial

public boolean computeBooleanIfAbsentPartial(K key,
                                             Object2BooleanFunction<? super K> mappingFunction)

Description copied from interface: Object2BooleanMap

If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map, unless the key is not present in the given mapping function.

This version of computeIfAbsent() uses a type-specific version of fastutil's Function. Since Function has a containsKey() method, it is possible to avoid adding a key by having containsKey() return false for that key.

Specified by:

computeBooleanIfAbsentPartial in interface Object2BooleanMap<K>

Parameters:

key - key with which the specified value is to be associated.

mappingFunction - the function to compute a value.

Returns:

the current (existing or computed) value associated with the specified key.

See Also:

Map.computeIfAbsent(Object, java.util.function.Function)

computeBooleanIfPresent

public boolean computeBooleanIfPresent(K key,
                                       java.util.function.BiFunction<? super K,? super java.lang.Boolean,? extends java.lang.Boolean> remappingFunction)

Description copied from interface: Object2BooleanMap

If the value for the specified key is present, attempts to compute a new mapping given the key and its current mapped value.

Specified by:

computeBooleanIfPresent in interface Object2BooleanMap<K>

Parameters:

key - key with which the specified value is to be associated.

remappingFunction - the function to compute a value.

Returns:

the new value associated with the specified key, or the default return value if none.

See Also:

Map.computeIfPresent(Object, java.util.function.BiFunction)

computeBoolean

public boolean computeBoolean(K key,
                              java.util.function.BiFunction<? super K,? super java.lang.Boolean,? extends java.lang.Boolean> remappingFunction)

Description copied from interface: Object2BooleanMap

Attempts to compute a mapping for the specified key and its current mapped value (or null if there is no current mapping).

If the function returns null, the mapping is removed (or remains absent if initially absent). If the function itself throws an (unchecked) exception, the exception is rethrown, and the current mapping is left unchanged.

Specified by:

computeBoolean in interface Object2BooleanMap<K>

Parameters:

key - key with which the specified value is to be associated.

remappingFunction - the function to compute a value.

Returns:

the new value associated with the specified key, or the default return value if none.

Map.compute(Object, java.util.function.BiFunction)

mergeBoolean

public boolean mergeBoolean(K key,
                            boolean value,
                            java.util.function.BiFunction<? super java.lang.Boolean,? super java.lang.Boolean,? extends java.lang.Boolean> remappingFunction)

Description copied from interface: Object2BooleanMap

If the specified key is not already associated with a value, associates it with the given value. Otherwise, replaces the associated value with the results of the given remapping function, or removes if the result is null.

Specified by:

mergeBoolean in interface Object2BooleanMap<K>

Parameters:

key - key with which the resulting value is to be associated.

value - the value to be merged with the existing value associated with the key or, if no existing value is associated with the key, to be associated with the key.

remappingFunction - the function to recompute a value if present.

Returns:

the new value associated with the specified key, or the default return value if no value is associated with the key.
