Since attempting to destructure such an object without data properties would not make sense, no componentN() functions are generated. Unlike a data class, a data object does not have any data properties. The singleton pattern restricts the instantiation of a class to a single instance, which would be violated by allowing copies of the instance to be created. Because a data object declaration is intended to be used as singleton objects, no copy() function is generated. While data object and data class declarations are often used together and have some similarities, there are some functions that are not generated for a data object: Differences between data objects and data classes The generated hashCode() function has behavior that is consistent with the equals() function, so that all runtime instances of a data object have the same hash code.

Println(MySingleton = evilTwin) // falseįun createInstanceViaReflection(): MySingleton as Constructor).newInstance() Some java classes have some predefined constants. Even when a library forcefully creates a second instance of MySingleton, its `equals` method returns true: Much of the time, well find ourselves dealing with objects that might have.
