Enum Constant Detail

MANUAL

public static final Acknowledgment.Strategy MANUAL

Acknowledgment managed by the user code. No automatic acknowledgment is performed. This strategy is only supported by methods consuming Message instances.

PRE_PROCESSING

public static final Acknowledgment.Strategy PRE_PROCESSING

Acknowledgment performed automatically before the processing of the message by the user code.

POST_PROCESSING

public static final Acknowledgment.Strategy POST_PROCESSING

Acknowledgment performed automatically once the message has been processed. When POST_PROCESSING is used, the incoming message is acknowledged when the produced message is acknowledged. Notice that this mode is not supported for all signatures. When supported, it's the default policy.

NONE

public static final Acknowledgment.Strategy NONE

No acknowledgment is performed, neither implicitly or explicitly. It means that the incoming messages are going to be acknowledged in a different location or using a different mechanism.

Method Detail

values

public static Acknowledgment.Strategy[] 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 (Acknowledgment.Strategy c : Acknowledgment.Strategy.values())
    System.out.println(c);

Returns:

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

valueOf

public static Acknowledgment.Strategy 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
