build

abstract fun build(): PersistentCollection<E>(source)

Returns a persistent collection with the same contents as this builder.

This method can be called multiple times.

If operations applied on this builder have caused no modifications:

  • on the first call it returns the same persistent collection instance this builder was obtained from.

  • on subsequent calls it returns the same previously returned persistent collection instance.
