Enum Constant Detail

TRANSACTIONAL

public static final AMQPProperties.TransactionMode TRANSACTIONAL

Indicates batches of messages should be sent using a transaction. While this provides ACID guarantees, it has a negative impact on performance.

PUBLISHER_ACK

public static final AMQPProperties.TransactionMode PUBLISHER_ACK

Indicates batches of messages should be sent and confirmed using Publisher Acknowledgements. This ensures the sender of messages waits for an Acknowledgement from the server before moving on. However, it doesn't provide for full ACID guarantees. When delivery fails, some messages may still have been delivered.

This setting does ensure that messages generated by the same Aggregate are published to the exchange in the order they were published by the aggregate.

Note that not all AMQP implementations support publisher acks.

NONE

public static final AMQPProperties.TransactionMode NONE

No transactional guarantees. Batches of messages are sent and no confirmation is requested from the server.

Method Detail

values

public static AMQPProperties.TransactionMode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (AMQPProperties.TransactionMode c : AMQPProperties.TransactionMode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static AMQPProperties.TransactionMode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
