Enum Constant and Description
Asynchronous With this replication policy, message/state is replicated without soliciting an acknowledgement from the backup engine cluster instances.
Pipelined With this replication policy, message/state is replicated soliciting acknowledgements from the backup engine cluster instance(s) but inbound message processing is not blocked waiting for the acknowledgement to be received.

Method Summary

Modifier and Type	Method and Description

Enum Constant Detail

Asynchronous

public static final AepEngine.ReplicationPolicy Asynchronous

With this replication policy, message/state is replicated without soliciting an acknowledgement from the backup engine cluster instances. Therefore, inbound messages that trigger the state/message replication are acknowledged without waiting from stability acknowledgement from the backup cluster instance(s).

Pipelined

public static final AepEngine.ReplicationPolicy Pipelined

With this replication policy, message/state is replicated soliciting acknowledgements from the backup engine cluster instance(s) but inbound message processing is not blocked waiting for the acknowledgement to be received. Inbound messages are processed in a pipelined manner in parallel with the replication traffic. However, inbound messages that trigger the state/message replication are not acknowledged up stream until stability notifications are received from the backup instance(s).

Method Detail

values

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

Returns:

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

valueOf

public static AepEngine.ReplicationPolicy 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
