This package contains implementations of the Closure, Predicate, Transformer and Factory interfaces. These provide simple callbacks for processing with collections.

WARNING: from v4.1 onwards several unsafe classes in this package will not be serializable anymore in order to prevent potential remote code execution exploits.

Classes considered to be unsafe are:

  • CloneTransformer
  • ForClosure
  • InstantiateFactory
  • InstantiateTransformer
  • InvokerTransformer
  • PrototypeFactory$PrototypeCloneFactory
  • PrototypeFactory$PrototypeSerializationFactory
  • WhileClosure
