Field Details

AUTO

public static final AcknowledgeMode AUTO

Messages sent or received from the session are automatically acknowledged. This is the simplest mode and enables once-only message delivery guarantee.

CLIENT

public static final AcknowledgeMode CLIENT

Messages are acknowledged once the message listener implementation has called Message.acknowledge(). This mode gives the application (rather than the JMS provider) complete control over message acknowledgement.

DUPS_OK

public static final AcknowledgeMode DUPS_OK

Similar to auto acknowledgment except that said acknowledgment is lazy. As a consequence, the messages might be delivered more than once. This mode enables at-least-once message delivery guarantee.

Method Details

getMode

public int getMode()

of

public static AcknowledgeMode of(String mode)

Creates an AcknowledgeMode of the given mode. The mode may be auto, client, dupsok or a non-standard acknowledge mode that can be parsed as an integer.

Parameters:

mode - the mode

Returns:

the acknowledge mode
