retainWhere method

void retainWhere (bool test(E element))

Remove all elements not matched by test.

This method is inefficient since it works by repeatedly removing single elements, each of which can take linear time.

Implementation

void retainWhere(bool test(E element)) {
  _filterWhere(test, false);
}
