      public final String getSerialVersionUIDStr()
      Return the serialVersionUID string for this class. The serialVersionUID defines a set of classes all with the same name that have evolved from a common root class and agree to be serialized and deserialized using a common format.

    • getActualSerialVersionUID

      public static final long getActualSerialVersionUID(Class<?> clazz)
      Return the actual (computed) serialVersionUID for this class.

    • getActualSerialVersionUID

      public final long getActualSerialVersionUID()
      Return the actual (computed) serialVersionUID for this class.

    • getActualSerialVersionUIDStr

      public ObjectStreamField[] getFields()
      Return an array of the fields of this serializable class.
      Returns:
      an array containing an element for each persistent field of this class. Returns an array of length zero if there are no fields.
