forEach

Performs given function f for each entry of the builder, using given state as initial traversal state.

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

Parameters

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

throws

RibuError.ModifiedBuilderWhileLoopingOverItError if the builder is modified while looping over it

example

HashMultiMapHashValue.of([1, 'a'], [2, 'b'], [1, 'c']).toBuilder().forEach((entry, i, halt) => {
console.log([entry[1], entry[0]]);
if (i >= 1) halt();
})
