    • lookup

      Find the descriptor for a class that can be serialized. Creates an ObjectStreamClass instance if one does not exist yet for class. Null is returned if the specified class does not implement java.io.Serializable or java.io.Externalizable.

      Parameters:
      cl - class for which to get the descriptor
      Returns:
      the class descriptor for the specified class

    • lookupAny

      Returns the descriptor for any class, regardless of whether it implements Serializable.

      Parameters:
      cl - class for which to get the descriptor
      Returns:
      the class descriptor for the specified class

    • getName

      Returns the name of the class described by this descriptor. This method returns the name of the class in the format that is used by the Class.getName() method.

      Returns:
      a string representing the name of the class

    • getSerialVersionUID

      public 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. NonSerializable classes have a serialVersionUID of 0L.

      Returns:
      the SUID of the class described by this descriptor

    • forClass

      public 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:
      the Class instance that this descriptor represents

    • 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.
      Since:

    • getField

      Get the field of this class by name.

      Parameters:
      name - the name of the data field to look for
      Returns:
      The ObjectStreamField object of the named field or null if there is no such named field.

    • toString

      Return a string describing this ObjectStreamClass.

      Overrides:
      toString in class Object
      Returns:
