Enum RetryPolicy

java.lang.Object
  java.lang.Enum<RetryPolicy>
      org.axonframework.eventhandling.RetryPolicy

All Implemented Interfaces:

Serializable, Comparable<RetryPolicy>

public enum RetryPolicy
extends Enum<RetryPolicy>

This policy tells the EventProcessingScheduler how it should deal with failed transactions.

• SKIP_FAILED_EVENT will tell the scheduler to ignore the failure and schedule a new transaction to continue processing.
• RETRY_TRANSACTION tells the scheduler to offer all the events in the failed transaction to the event listener in a new transaction.
• RETRY_LAST_EVENT tell the scheduler to only offer the last event form this transaction to the event listener. This event will be handled in a new transaction.

0.4

Enum Constant Detail

SKIP_FAILED_EVENT

public static final RetryPolicy SKIP_FAILED_EVENT

Tells the scheduler to ignore the failure and schedule a new transaction to continue processing. Note that any retry interval is ignored, and a new transaction is scheduled for immediate execution when this retry policy is applied.

RETRY_TRANSACTION

public static final RetryPolicy RETRY_TRANSACTION

Tells the scheduler to offer all the events in the failed transaction to the event listener in a new transaction.

RETRY_LAST_EVENT

public static final RetryPolicy RETRY_LAST_EVENT

Tells the scheduler to only offer the last event form this transaction to the event listener. This event will be handled in a new transaction.

Method Detail

values

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

Returns:

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

valueOf

public static RetryPolicy 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
