      UID for the class

    • getSerialVersionUID

      public final long getSerialVersionUID()
      Return the serialVersionUID 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.
      Returns:
      SerialVersionUID for this class.

    • getSerialVersionUIDStr

      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.
      Returns:
      UID for this class

    • getActualSerialVersionUID

      public static final long getActualSerialVersionUID(Class<?> clazz)
      Return the actual (computed) serialVersionUID for this class.
      Parameters:
      clazz - Class to get UID of

      Returns:
      UID for this class

    • forClass

      public final Class<?> forClass()
      Return the class in the local VM that this version is mapped to. Null is returned if there is no corresponding local class.
      Returns:
      Class this is mapped to

    • getFields

      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.
