TransformMapView

public TransformMapView(Map<K,V> map,
                        IgniteClosure<V,V1> clos,
                        IgnitePredicate<? super K>... preds)

Parameters:

map - Input map that serves as a base for the view.

clos - Transformer for map value transformation.

preds - Optional predicates. If predicates are not provided - all will be in the view.
