Boolean

hasValue(value, eqCompareropt) → {Boolean}

Parameters:

Returns:
Type
Boolean

invert(eqCompareropt) → {DictionaryMapBased.<TVal, Array.<TKey>>}

Inverts this dictionary by using its values as keys, and storing for each value a list of keys that previously pointed to that value. Therefore, the values in the inverted dictionary are lists. E.g., the dictionary {A=>5, B=>5, C=>2} inverts to the dictionary {5=>[A,B], 2=>[C]}. Therefore, you also cannot invert an inverted dictionary and obtain a dictionary equivalent to the original.
Parameters:
Name Type Attributes Description
eqComparer EqualityComparer.<TVal> <optional>
 Optional. Uses the default EqualityComparer if not given. You may also pass in this dictionary's comparer. It may make sense to use a separate comparer, as the values may be of different type than the keys.

DictionaryMapBased.<TVal, Array.<TKey>>

(generator) keys() → {IterableIterator.<TKey>}

Source:
Returns:
Type
IterableIterator.<TKey>
