Class Message.RecipientType

Enclosing Class:
Message
Implemented Interfaces:
Serializable
Known Direct Subclasses:
MimeMessage.RecipientType
public static class Message.RecipientType
extends java.lang.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.

Field Summary

static Message.RecipientType
BCC
The "Bcc"(blind carbon copy) recipients.
static Message.RecipientType
CC
The "Cc"(carbon copy) recipients.
static Message.RecipientType
TO
The "To"(primary) recipients.
protected String
type
The type of recipient, usually the name of a corresponding Internet standard header.

Constructor Summary

RecipientType(String type)
Constructor for use by subclasses.

Method Summary

protected Object
readResolve()
When deserializing a RecipientType, we need to make sure to return only one of the known static final instances defined in this class.

Field Details

BCC

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

CC

public static final Message.RecipientType CC
The "Cc"(carbon copy) recipients.

TO

public static final Message.RecipientType TO
The "To"(primary) recipients.

type

protected String type
The type of recipient, usually the name of a corresponding Internet standard header.

Constructor Details

RecipientType

protected RecipientType(String type)
Constructor for use by subclasses.

Method Details

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.
