Constructor Details

LazySortedMapImpl

public LazySortedMapImpl(boolean doPopulate,
 Supplier<? extends SortedMap<K,V>> supplier)

Creates a new LazySortedMapImpl<K,V> instance.

Parameters:

doPopulate - true if the provided supplier will put values to the map on initialisation, false if it will create an empty map.

supplier - The supplier that initialises the internal map for this instance on the first it is needed.

LazySortedMapImpl

public LazySortedMapImpl(SortedMap<K,V> value)

Creates a new LazyMapImpl instance that is initialised with the given value.

Parameters:

value - The initialisation value.
