Message.RecipientType (Jakarta EE Platform API)

java.lang.Object
- jakarta.mail.Message.RecipientType

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

MimeMessage.RecipientType

Enclosing class:

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);

 
```

```
    The "Cc" (carbon copy) recipients.
  - BCC
```
public static final Message.RecipientType BCC
```
    The "Bcc" (blind carbon copy) recipients.
  - type
```

  - RecipientType
```
protected RecipientType(String type)
```
    Constructor for use by subclasses.
    
    Parameters:
    
    type - the recipient type
- Method Detail
  - 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.
    
    Returns:
    
    the RecipientType object instance
    
    Throws:
    
    ObjectStreamException - for object stream errors
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
