net.sf.saxon.ma.trie.ImmutableHashTrieMap<K,V>
All Implemented Interfaces:
Iterable<TrieKVP<K,V>>, ImmutableMap<K,V>
public abstract class ImmutableHashTrieMap<K,V> extends Object implements ImmutableMap<K,V>, Iterable<TrieKVP<K,V>>

  • Constructor Details

    • ImmutableHashTrieMap

      public ImmutableHashTrieMap()

  • Method Details

    • empty

      public static <K, V> ImmutableHashTrieMap<K,V> empty()

    • put

      public ImmutableHashTrieMap<K,V> put(K key, V value)
      Description copied from interface: ImmutableMap
      Add a new entry to the map. If an entry already exists with the given key, the returned map will contain this entry, but not the existing entry.
      Specified by:
      put in interface ImmutableMap<K,V>
      Parameters:
      key - the key to use to retrieve this item
      value - the value stored for this item
      Returns:
      a new map with this item added

    • remove

      public ImmutableHashTrieMap<K,V> remove(K key)
      Description copied from interface: ImmutableMap
      Remove an entry from the map. If no entry exists with the given key, the returned map will have identical contents to the original map (and may, in fact, be the original map itself).
      Specified by:
      remove in interface ImmutableMap<K,V>
      Parameters:
      key - the key for the entry to remove
      Returns:
      a new map with the entry with the given key removed (or a map with the original contents if no entry was found for the given key).

    • get

      public V get(K key)
      Description copied from interface: ImmutableMap
      Retrieve a stored value from the map based on the key for the associated entry. If no entry exists with the given key, we return None.
      Specified by:
      get in interface ImmutableMap<K,V>
      Parameters:
      key - the key for the entry to retrieve
      Returns:
      Some(value) if an entry exists with the given key, or None if no entry with the given key was found.
