startKeyLss

startKeyLss(keys: ParamListType);

The startKeyLss method of the MergeIterator class sets a start position of the iterator for the merged view at the object before the key specified in the keys parameter. If the attached dictionaries do not have the same keys, the types of the values specified in the keys parameter must be the same as the subset of common keys of the attached dictionaries.

This method is used in conjunction with the back method.
