default value for CascadeType in Hibernate

I am using Hibernate to persist this bean.

import javax.persistence.*;

@Entity
public class Person {
    @Id @GeneratedValue
    private int id;
    @Column
    private String name;
    @OneToOne
    private Address addr;
}

What is the CascadeType for addr?

CascadeType defaults to the empty array . See CascadeType in Annotation Type OneToOne

By default no operations are cascaded.

You can check the source of @OneToOne at here . No operations are cascaded by default

  /**
     * (Optional) The operations that must be cascaded to
      * the target of the association.
     *
     * <p> By default no operations are cascaded.
     */
   CascadeType[] cascade() default {};
