Message

public static class Message.RecipientType
extends Object
implements Serializable

This inner class defines the types of recipients allowed by the Message class. The currently defined types are TO, CC and BCC. Note that this class only has a protected constructor, thereby restricting new Recipient types to either this class or subclasses. This effectively implements an enumeration of the allowed Recipient types. The following code sample shows how to use this class to obtain the "TO" recipients from a message.

 Message msg = folder.getMessages(1);
 Address[] a = m.getRecipients(Message.RecipientType.TO);

方法详细信息

readResolve

protected Object readResolve()
                      throws ObjectStreamException

When deserializing a RecipientType, we need to make sure to return only one of the known static final instances defined in this class. Subclasses must implement their own readResolve method that checks for their known instances before calling this super method.

抛出：

ObjectStreamException

toString

public String toString()
