ru.yoomoney.tech.dbqueue.settings.FailRetryType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<FailRetryType>

public enum FailRetryType
extends java.lang.Enum<FailRetryType>

Strategy type for the task deferring in case of retry.

10.07.2017

Enum Constant Summary

Enum Constants

Enum Constant	Description
ARITHMETIC_BACKOFF	The task is deferred by an arithmetic progression relative to the interval FailureSettings.getRetryInterval().
GEOMETRIC_BACKOFF	The task is deferred exponentially relative to the interval FailureSettings.getRetryInterval() The denominator of the progression equals 2.
LINEAR_BACKOFF	The task is deferred with fixed delay.

Method Summary

Modifier and Type	Method	Description
static FailRetryType	valueOf(java.lang.String name)	Returns the enum constant of this type with the specified name.
static FailRetryType[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

GEOMETRIC_BACKOFF

public static final FailRetryType GEOMETRIC_BACKOFF

The task is deferred exponentially relative to the interval FailureSettings.getRetryInterval() The denominator of the progression equals 2. First 6 terms: 1 2 4 8 16 32

ARITHMETIC_BACKOFF

public static final FailRetryType ARITHMETIC_BACKOFF

The task is deferred by an arithmetic progression relative to the interval FailureSettings.getRetryInterval(). The difference of progression equals 2. First 6 terms: 1 3 5 7 9 11

LINEAR_BACKOFF

public static final FailRetryType LINEAR_BACKOFF

The task is deferred with fixed delay.

Fixed delay value is set through FailureSettings.getRetryInterval()

Method Detail

values

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

Returns:

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

valueOf

public static FailRetryType 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
