Method Detail

get

public V get(@Nullable
             java.lang.Object key)

Specified by:

get in interface java.util.Map<K,V>

Specified by:

get in class ImmutableMap<K,V>

keySet

public ImmutableSortedSet<K> keySet()

Description copied from class: ImmutableSortedMap

Returns an immutable sorted set of the keys in this map.

Specified by:

keySet in interface java.util.Map<K,V>

Specified by:

keySet in interface java.util.SortedMap<K,V>

Specified by:

keySet in class ImmutableSortedMap<K,V>

size

public int size()

Specified by:

size in interface java.util.Map<K,V>

Overrides:

size in class ImmutableSortedMap<K,V>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface java.util.Map<K,V>

Overrides:

isEmpty in class ImmutableMap<K,V>

values

public ImmutableCollection<V> values()

Description copied from class: ImmutableSortedMap

Returns an immutable collection of the values in this map, sorted by the ordering of the corresponding keys.

Specified by:

values in interface java.util.Map<K,V>

Specified by:

values in interface java.util.SortedMap<K,V>

Specified by:

values in class ImmutableSortedMap<K,V>

toString

public java.lang.String toString()

Overrides:

toString in class ImmutableMap<K,V>

isPartialView

boolean isPartialView()

Overrides:

isPartialView in class ImmutableSortedMap<K,V>

entrySet

public ImmutableSet<java.util.Map.Entry<K,V>> entrySet()

Description copied from class: ImmutableSortedMap

Returns an immutable set of the mappings in this map, sorted by the key ordering.

Specified by:

entrySet in interface java.util.Map<K,V>

Specified by:

entrySet in interface java.util.SortedMap<K,V>

Overrides:

entrySet in class ImmutableSortedMap<K,V>

createEntrySet

ImmutableSet<java.util.Map.Entry<K,V>> createEntrySet()

Specified by:

createEntrySet in class ImmutableMap<K,V>

asMultimap

public ImmutableSetMultimap<K,V> asMultimap()

Description copied from class: ImmutableMap

Returns a multimap view of the map.

Overrides:

asMultimap in class ImmutableMap<K,V>

headMap

public ImmutableSortedMap<K,V> headMap(K toKey,
                                       boolean inclusive)

Description copied from class: ImmutableSortedMap

This method returns a ImmutableSortedMap, consisting of the entries whose keys are less than (or equal to, if inclusive) toKey.

The SortedMap.headMap(K) documentation states that a submap of a submap throws an IllegalArgumentException if passed a toKey greater than an earlier toKey. However, this method doesn't throw an exception in that situation, but instead keeps the original toKey.

Specified by:

headMap in interface java.util.NavigableMap<K,V>

Specified by:

headMap in class ImmutableSortedMap<K,V>

tailMap

public ImmutableSortedMap<K,V> tailMap(K fromKey,
                                       boolean inclusive)

Description copied from class: ImmutableSortedMap

This method returns a ImmutableSortedMap, consisting of the entries whose keys are greater than (or equal to, if inclusive) fromKey.

The SortedMap.tailMap(K) documentation states that a submap of a submap throws an IllegalArgumentException if passed a fromKey less than an earlier fromKey. However, this method doesn't throw an exception in that situation, but instead keeps the original fromKey.

Specified by:

tailMap in interface java.util.NavigableMap<K,V>

Specified by:

tailMap in class ImmutableSortedMap<K,V>

createDescendingMap

ImmutableSortedMap<K,V> createDescendingMap()
