totalRetryTime - The amount of time spent retrying

Method Details

getWorkflowContext

public DefaultWorkflowContext getWorkflowContext()

Gets the context of the current workflow.

The workflow context can be used in retry handlers to schedule timers (via the DefaultWorkflowContext.createTimer(java.time.Duration) methods) for implementing delays between retries. It can also be used to implement time-based retry logic by using the DefaultWorkflowContext.getCurrentInstant() method.

Returns:

the context of the parent workflow

getLastFailure

public WorkflowFailureDetails getLastFailure()

Gets the details of the previous task failure, including the exception type, message, and callstack.

Returns:

the details of the previous task failure

getLastAttemptNumber

public int getLastAttemptNumber()

Gets the previous retry attempt number. This number starts at 1 and increments each time the retry handler is invoked for a particular task failure.

Returns:

the previous retry attempt number

getTotalRetryTime

public Duration getTotalRetryTime()

Gets the total amount of time spent in a retry loop for the current task.

Returns:

the total amount of time spent in a retry loop for the current task
