de.gebit.integrity.parameter.conversion.conversions.java.other.OptionalToContainedObject

public class OptionalToContainedObject
extends Conversion<java.util.Optional,java.lang.Object>

This conversion is necessary to allow Optionals to be used as parameters. It basically resolves them to the contained object (which may have to be converted further afterwards).
