forEach(f: (entry: [K, V], index: number, halt: () => void) => void, options?: {
      state?: TraverseState;
    }): void;

Parameters

Name	Type	Description
f	(entry: [K, V], index: number, halt: () => void) => void	the function to perform for each element, receiving: - entry: the next key-value entry - index: the index of the element - halt: a function that, if called, ensures that no new elements are passed

O(N)

getKeys

Returns a collection representing the keys currently associated with given value.

note

since it is unsafe to return the internal builder object, the result colleciton will be build upon each call to getKeys.

example

const m = HashBiMultiMap.of([1, 'a'], [2, 'b']).toBuilder()
m.getKeys('a').toArray()   // => [1]
m.getKeys('z').toArray()   // => []

Parameters

Name	Type	Description

note

since it is unsafe to return the internal builder object, the result colleciton will be build upon each call to getValues.

const m = HashBiMultiMap.of([1, 'a'], [2, 'b']).toBuilder()
m.getValues(1).toArray()   // => ['a']
m.getValues(3).toArray()   // => []
