Constructor Summary

Constructors

Constructor	Description
RetrySetup(String transactionManagerName, String description, Supplier<T> transaction)	Constructor that uses the aspect default values for maximum retries, initial delay, and maximum delay.
RetrySetup(String transactionManagerName, String description, Supplier<T> transaction, int maxRetries, long initialDelay, long maximumDelay)	Primary constructor.
RetrySetup(String transactionManagerName, String description, Supplier<T> transaction, RetryTransaction annotation)	Constructor that uses the values from a @RetryTransaction annotation, if not null, for maximum retries, initial delay, and maximum delay, otherwise falling back to the aspect defaults.

Method Summary

Modifier and Type	Method	Description
String	getDescription()	Get a description of the transaction for logging purposes.
long	getInitialDelay()	Get the initial delay between retry attempts in milliseconds.
long	getMaximumDelay()	Get the maximum delay between retry attempts in milliseconds.
int	getMaxRetries()	Get the maximum number of transaction retry attempts.
Supplier<T>	getTransaction()	Get the transaction to perform and possibly retry.

Constructor Details

RetrySetup

public RetrySetup(String transactionManagerName,
 String description,
 Supplier<T> transaction)

Constructor that uses the aspect default values for maximum retries, initial delay, and maximum delay.

Parameters:

transactionManagerName - the name of the associated transaction manager, if any, otherwise null

description - description of transaction for logging purposes

transaction - the transaction that should be invoked and retried as needed

RetrySetup

public RetrySetup(String transactionManagerName,
 String description,
 Supplier<T> transaction,
 RetryTransaction annotation)

Constructor that uses the values from a @RetryTransaction annotation, if not null, for maximum retries, initial delay, and maximum delay, otherwise falling back to the aspect defaults.

Parameters:

transactionManagerName - the name of the associated transaction manager, if any, otherwise null

description - description of transaction for logging purposes

transaction - the transaction that should be invoked and retried as needed

annotation - @RetryTransaction annotation, or null to use aspect defaults

RetrySetup

public RetrySetup(String transactionManagerName,
 String description,
 Supplier<T> transaction,
 int maxRetries,
 long initialDelay,
 long maximumDelay)

Primary constructor.

Parameters:

transactionManagerName - the name of the associated transaction manager, if any, otherwise null

description - description of transaction for logging purposes

transaction - the transaction that should be invoked and retried as needed

maxRetries - maximum number of transaction retry attempts, or -1 to use the aspect default

initialDelay - initial delay between retry attempts in milliseconds, or -1 to use the aspect default

maximumDelay - maximum delay between retry attempts in milliseconds, or -1 to use the aspect default

Method Details

getTransactionManagerName

public String getTransactionManagerName()

Get name of the associated transaction manager, if any.

This value is used by the woven aspect to avoid redundant nested retries within an already-open transaction.

Returns:

transaction manager name, or null to be invisible to redundancy checks

getDescription

public String getDescription()

Get a description of the transaction for logging purposes.

Returns:

transaction description

getTransaction

public Supplier<T> getTransaction()

Get the transaction to perform and possibly retry.

Returns:

transaction

getMaxRetries

public int getMaxRetries()

Get the maximum number of transaction retry attempts.

Returns:

maximum number of retries, or -1 to use the aspect default

getInitialDelay

public long getInitialDelay()

Get the initial delay between retry attempts in milliseconds.

Returns:

initial delay between retry attempts, or -1 to use the aspect default

getMaximumDelay

public long getMaximumDelay()

Get the maximum delay between retry attempts in milliseconds.

Returns:

maximum delay between retry attempts, or -1 to use the aspect default
