      public long get(Object key)
      Description copied from interface: TObjectLongMap

    • put

      public long put(K key, long value)
      Description copied from interface: TObjectLongMap
      Inserts a key/value pair into the map.
      Specified by:
      put in interface TObjectLongMap<K>
      Returns:
      the previous value associated with key, or the "no entry" value if none was found (see TObjectLongMap.getNoEntryValue()).

    • remove

      public long remove(Object key)
      Description copied from interface: TObjectLongMap
      Deletes a key/value pair from the map.
      Specified by:
      remove in interface TObjectLongMap<K>
      Parameters:

    • putAll

      public void putAll(TObjectLongMap<? extends K> m)
      Description copied from interface: TObjectLongMap
      Put all the entries from the given map into this map.
      Specified by:
      putAll in interface TObjectLongMap<K>
      Parameters:
      m - The map from which entries will be obtained to put into this map.

    • putAll

      public void putAll(Map<? extends K,? extends Long> map)
      Description copied from interface: TObjectLongMap
      Copies all of the mappings from the specified map to this map (optional operation). The effect of this call is equivalent to that of calling put(k, v) on this map once for each mapping from key k to value v in the specified map. The behavior of this operation is undefined if the specified map is modified while the operation is in progress.
      Specified by:
      putAll in interface TObjectLongMap<K>
      Parameters:
      map - mappings to be stored in this map

    • clear

      public void clear()
      Description copied from interface: TObjectLongMap
      Removes all of the mappings from this map (optional operation). The map will be empty after this call returns.
      Specified by:
      clear in interface TObjectLongMap<K>

    • keySet

      public Set<K> keySet()
      Description copied from interface: TObjectLongMap
      Returns a Set view of the keys contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll, and clear operations. It does not support the add or addAll operations.
      Specified by:
      keySet in interface TObjectLongMap<K>
      Returns:
      a set view of the keys contained in this map

    • keys

      public Object[] keys()
      Description copied from interface: TObjectLongMap
      Returns a copy of the keys of the map as an array. Changes to the array of keys will not be reflected in the map nor vice-versa.
      Specified by:
      keys in interface TObjectLongMap<K>
      Returns:
      a copy of the keys of the map as an array.

    • keys

      public K[] keys(K[] array)
      Description copied from interface: TObjectLongMap
      Returns a copy of the keys of the map as an array. Changes to the array of keys will not be reflected in the map nor vice-versa.
      Specified by:
      keys in interface TObjectLongMap<K>
      Parameters:
      array - the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same type is allocated for this purpose.
      Returns:
      the keys of the map as an array.

    • valueCollection

      public TLongCollection valueCollection()
      Description copied from interface: TObjectLongMap
      Returns a TLongCollection view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa. If the map is modified while an iteration over the collection is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The collection supports element removal, which removes the corresponding mapping from the map, via the TLongIterator.remove, TLongCollection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.
      Specified by:
      valueCollection in interface TObjectLongMap<K>
      Returns:
      a collection view of the values contained in this map

    • values

      public long[] values()
      Description copied from interface: TObjectLongMap
      Returns the values of the map as an array of long values. Changes to the array of values will not be reflected in the map nor vice-versa.
      Specified by:
      values in interface TObjectLongMap<K>
      Returns:
      the values of the map as an array of long values.

    • values

      public long[] values(long[] array)
      Description copied from interface: TObjectLongMap
      Returns the values of the map using an existing array. Changes to the array of values will not be reflected in the map nor vice-versa.
      Specified by:
      values in interface TObjectLongMap<K>
      Parameters:
      array - the array into which the elements of the list are to be stored, if it is big enough; otherwise, a new array of the same type is allocated for this purpose.
      Returns:
      the values of the map as an array of long values.

    • equals

      public boolean equals(Object o)
      Description copied from interface: TObjectLongMap
      Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings. More formally, two maps m1 and m2 represent the same mappings if m1.entrySet().equals(m2.entrySet()). This ensures that the equals method works properly across different implementations of the Map interface.
      Specified by:
      equals in interface TObjectLongMap<K>
      Overrides:
      equals in class Object
      Parameters:
      o - object to be compared for equality with this map
      Returns:
      true if the specified object is equal to this map

    • hashCode

      public int hashCode()
      Description copied from interface: TObjectLongMap
      Returns the hash code value for this map. The hash code of a map is defined to be the sum of the hash codes of each entry in the map's entrySet() view. This ensures that m1.equals(m2) implies that m1.hashCode()==m2.hashCode() for any two maps m1 and m2, as required by the general contract of Object.hashCode().
      Specified by:
      hashCode in interface TObjectLongMap<K>
      Overrides:
      hashCode in class Object
      Returns:
      the hash code value for this map
      See Also:

      public String toString()
      Overrides:
      toString in class Object

    • getNoEntryValue

      public long getNoEntryValue()
      Description copied from interface: TObjectLongMap
      Returns the value that will be returned from TObjectLongMap.get(java.lang.Object) or TObjectLongMap.put(K, long) if no entry exists for a given key. The default value is generally zero, but can be configured during construction of the collection.
      Specified by:
      getNoEntryValue in interface TObjectLongMap<K>
      Returns:
      the value that represents a null value in this collection.
