DefaultRetryStrategy

public DefaultRetryStrategy(AtomicCommand<T> atomicCommand,
 int maxAttempts,
 long waitTime)

The constructor initializes the retry strategy with the atomic command to be executed, the maximum number of attempts, and the wait time between each attempt.

Parameter:

atomicCommand - atomic command

maxAttempts - maximal attempts

waitTime - wait time between retries

Methodendetails

execute

public T execute()
          throws IOException

Tries to execute the atomic command and returns its result if successful. If the atomic command throws an IOException, the retry strategy catches and records it. It repeats the execution of the atomic command for a specified number of attempts, waiting for a certain time interval between each attempt. If the maximum number of attempts is reached without a successful execution, the retry strategy throws the recorded exception.
