ListMap

@SerialVersionUID(3L) object ListMap extends MapFactory[[K, V] =>> ListMap[K, V]]

This object provides a set of operations to create ListMap values.

Note that each element insertion takes O(n) time, which means that creating a list map with n elements will take O(n2) time. This makes the builder suitable only for a small number of elements.
