Class MapComparisonPerformer<V>

java.lang.Object

org.whaka.util.reflection.comparison.performers.MapComparisonPerformer<V>

All Implemented Interfaces:

java.util.function.BiFunction<java.util.Map<?,? extends V>,java.util.Map<?,? extends V>,ComparisonResult>, java.util.function.BiPredicate<java.util.Map<?,? extends V>,java.util.Map<?,? extends V>>, ComparisonPerformer<java.util.Map<?,? extends V>>

public class MapComparisonPerformer<V>
extends java.lang.Object

Compares maps by keys, using specified delegate performer to check that values with the same key are equal in both maps. Can produce 3 kinds or complex results with 3 different ClassPropertyKey types:

• Maps have different size - mapped by 'Map#size' and contains map's sizes as values
• Maps have different key sets - mapped by 'Map#keySet' and contains key sets as values
• Different values with the same key - mapped by 'Map#(key)' where key is the object used as a key for the compared value, and contains actual and expected values from both maps (might be null, if maps contained nulls)

Note: key sets are compared with use of default Set.equals(Object) method! No custom performers are used, for objects are required to implement at least some hashCode\equals functionality to be used as map keys. If your map implementation required any more sophisticated key matching - please implement you own comparison performer for such a map.

Such a functionality implemented to perform maximum early assertion before starting actually deeply comparing map values. So comparison results might be not as informative as required in case of early assert. If so - please implement your own custom comparison performer.
