Class Predicates

org.apache.flink.architecture.common.Predicates

public class Predicates
extends Object

Common predicates for architecture tests.

NOTE: it is recommended to use methods that accept fully qualified class names instead of Class objects to reduce the risks of introducing circular dependencies between the project submodules.
