Class UberCollections

java.lang.Object

org.whaka.util.UberCollections

public class UberCollections
extends java.lang.Object

Note: methods

• containsAll(Collection, Collection, BiPredicate)
• containsAny(Collection, Collection, BiPredicate)
• containsEqualElements(Collection, Collection, BiPredicate)

Accept specific predicate that will be used to compare elements equality. But methods:

• containsAll(Collection, Collection)
• containsAny(Collection, Collection)
• containsEqualElements(Collection, Collection)

Use default 'deep-equal' predicate. See: deepEqualsPredicate()

Field Detail

DEEP_EQUALS_PREDICATE

public static final java.util.function.BiPredicate DEEP_EQUALS_PREDICATE

If both objects are collections - containsEqualElements(Collection, Collection, BiPredicate) is performed with this predicate. Otherwise - Objects.deepEquals(Object, Object) is performed.
