Class IteratorValueCache<T>

Parameters

• createIterator: (() => AsyncIterableIterator<T>)

  This callback creates a new iterator that is used to fill the cache.

  • • (): AsyncIterableIterator<T>

    • Returns AsyncIterableIterator<T>

• incrementalUpdates: boolean = false

  This is an optimization that will update the cache by appending new values at the end of the cache. The prerequisites for activating this feature are:

  • In a complete iteration of a new iterator all values need to be unique. The iterator is not allowed to return the same element twice.
  • New elements must appear at the beginning of the iteration and the previous elements need to stay the same. This way the iteration can stop as soon as an element, that is already in the cache, is encountered.
