Value Members

  1. def clear(): Unit

    Removes all keys and all values

  2. def findValue(key: K)(f: (V) ⇒ Boolean): Option[V]

    returns

    Some(value) for the first matching value where the supplied function returns true for the given key, if no matches it returns None

  3. def foreach(fun: (K, V) ⇒ Unit): Unit

    Applies the supplied function to all keys and their values

  4. def isEmpty: Boolean

    returns

    true if the underlying containers is empty, may report false negatives when the last remove is underway

  5. def keys: Iterable[K]

    Returns the key set.

  6. val mapSize: Int
  7. def put(key: K, value: V): Boolean

    Associates the value of type V with the key of type K

    Associates the value of type V with the key of type K

    returns

    true if the value didn't exist for the key previously, and false otherwise

  8. def remove(key: K): Option[Iterable[V]]

    Disassociates all the values for the specified key

    Disassociates all the values for the specified key

    returns

    None if the key wasn't associated at all, or Some(scala.Iterable[V]) if it was associated

  9. def remove(key: K, value: V): Boolean

    Disassociates the value of type V from the key of type K

    Disassociates the value of type V from the key of type K

    returns

    true if the value was disassociated from the key and false if it wasn't previously associated with the key

  10. def removeValue(value: V): Unit

    Removes the specified value from all keys

  11. val valueComparator: Comparator[V]
  12. def valueIterator(key: K): Iterator[V]

    Returns an Iterator of V containing the values for the supplied key, or an empty iterator if the key doesn't exist

  13. def values: Set[V]

    Returns the union of all value sets.
