Class Message.RecipientType

java.lang.Object
|
+--javax.mail.Message.RecipientType
Enclosing Class:

All 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.

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

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.

Parameters:
type

Method Details

readResolve

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. Subclasses must implement their own readResolve method that checks for their known instances before calling this super method.
