Method Detail

createMessage

public Message createMessage(String content,
                             String contentType,
                             String encoding,
                             String subject)

Description copied from interface: OperationSetBasicInstantMessaging

Create a Message instance for sending arbitrary MIME-encoding content.

Specified by:

createMessage in interface OperationSetBasicInstantMessaging

Specified by:

createMessage in class AbstractOperationSetBasicInstantMessaging

Parameters:

content - content value

contentType - the MIME-type for content

encoding - encoding used for content

subject - a String subject or null for now subject.

Returns:

the newly created message.

sendInstantMessage

public void sendInstantMessage(Contact to,
                               Message message)
                        throws IllegalStateException,
                               IllegalArgumentException

Sends the message to the destination indicated by the to contact.

Parameters:

to - the Contact to send message to

message - the Message to send.

Throws:

IllegalStateException - if the underlying Zeroconf stack is not registered and initialized.

IllegalArgumentException - if to is not an instance belonging to the underlying implementation.

fireMessageReceived

public void fireMessageReceived(Message message,
                                Contact from)

Notifies all registered message listeners that a message has been received.

Overrides:

fireMessageReceived in class AbstractOperationSetBasicInstantMessaging

Parameters:

message - the Message that has been received.

from - the Contact that message was received from.

isOfflineMessagingSupported

public boolean isOfflineMessagingSupported()

Determines whether the protocol provider (or the protocol itself) support sending and receiving offline messages. Most often this method would return true for protocols that support offline messages and false for those that don't. It is however possible for a protocol to support these messages and yet have a particular account that does not (i.e. feature not enabled on the protocol server). In cases like this it is possible for this method to return true even when offline messaging is not supported, and then have the sendMessage method throw an OperationFailedException with code - OFFLINE_MESSAGES_NOT_SUPPORTED.

Returns:

true if the protocol supports offline messages and false otherwise.

isContentTypeSupported

public boolean isContentTypeSupported(String contentType)

Determines whether the protocol supports the supplied content type

Parameters:

contentType - the type we want to check

Returns:

true if the protocol supports it and false otherwise.
