Method Details

comparator

public Comparator<? super K> comparator()

Description copied from interface: Object2BooleanSortedMap

Returns the comparator associated with this sorted set, or null if it uses its keys' natural ordering.

Specified by:

comparator in interface Object2BooleanSortedMap<K>

Specified by:

comparator in interface SortedMap<K,Boolean>

See Also:

• SortedMap.comparator()

object2BooleanEntrySet

public ObjectSortedSet<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>

Specified by:

object2BooleanEntrySet in interface Object2BooleanSortedMap<K>

Overrides:

object2BooleanEntrySet in class Object2BooleanMaps.EmptyMap<K>

Returns:

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

See Also:

• Map.entrySet()

entrySet

@Deprecated
public ObjectSortedSet<Map.Entry<K,Boolean>> entrySet()

Deprecated.

Please use the corresponding type-specific method instead.

Returns a sorted-set view of the mappings contained in this map.

Specified by:

entrySet in interface Map<K,Boolean>

Specified by:

entrySet in interface Object2BooleanMap<K>

Specified by:

entrySet in interface Object2BooleanSortedMap<K>

Specified by:

entrySet in interface SortedMap<K,Boolean>

Returns:

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

See Also:

• SortedMap.entrySet()

keySet

public ObjectSortedSet<K> keySet()

Description copied from interface: Object2BooleanMap

Specified by:

keySet in interface Map<K,Boolean>

Specified by:

keySet in interface Object2BooleanMap<K>

Specified by:

keySet in interface Object2BooleanSortedMap<K>

Specified by:

keySet in interface SortedMap<K,Boolean>

Overrides:

keySet in class Object2BooleanMaps.EmptyMap<K>

Returns:

a set view of the keys contained in this map.

See Also:

• Map.keySet()

subMap

public Object2BooleanSortedMap<K> subMap(K from,
 K to)

Description copied from interface: Object2BooleanSortedMap

Returns a view of the portion of this sorted map whose keys range from fromKey, inclusive, to toKey, exclusive.

headMap

public Object2BooleanSortedMap<K> headMap(K to)

Description copied from interface: Object2BooleanSortedMap

Returns a view of the portion of this sorted map whose keys are strictly less than toKey.

Specified by:

• SortedMap.headMap(Object)

tailMap

public Object2BooleanSortedMap<K> tailMap(K from)
