Enum Constant Detail

None

public static final AckPolicy None

Messages are acknowledged as soon as the server sends them. Clients do not need to ack.

All

public static final AckPolicy All

All messages with a sequence number less than the message acked are also acknowledged. E.g. reading a batch of messages 1 .. 100. Ack on message 100 will acknowledge 1 .. 99 as well.

Explicit

public static final AckPolicy Explicit

Each message must be acknowledged individually. Message can be acked out of sequence and create gaps of unacknowledged messages in the consumer.

Method Detail

values

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

Returns:

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

valueOf

public static AckPolicy valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<AckPolicy>
