Class IterationTimeBoundedBudget

java.lang.Object

org.apache.camel.support.task.budget.IterationTimeBoundedBudget

All Implemented Interfaces:

Budget, IterationBudget, TimeBudget

public class IterationTimeBoundedBudget
extends Object
implements IterationBudget, TimeBudget

This task budget limits the execution by both a given number of iterations or a maximum amount of time for the execution. When evaluating the budget, the iteration takes precedence over the time budget (hence why: Iteration Time Budget).

Method Detail

initialDelay

public long initialDelay()

Description copied from interface: Budget

Defines an initial delay before running the task

Specified by:

initialDelay in interface Budget

Returns:

the initial delay, in milliseconds, before running the task

interval

public long interval()

Description copied from interface: Budget

The interval between each task execution

Specified by:

interval in interface Budget

Returns:

the interval, in milliseconds, for each task execution

maxIterations

public int maxIterations()

Description copied from interface: IterationBudget

The maximum number of iterations

Specified by:

maxIterations in interface IterationBudget

Returns:

the maximum number of iterations

iteration

public int iteration()

Description copied from interface: IterationBudget

The current number of iterations

Specified by:

iteration in interface IterationBudget

Returns:

the current number of iterations

next

public boolean next()

Description copied from interface: Budget

Move the task to the next iteration

Specified by:

next in interface Budget

Returns:

true if the task can continue or false otherwise

canContinue

public boolean canContinue()

Description copied from interface: Budget

Whether the task has budget to continue executing or not

Specified by:

canContinue in interface Budget

Returns:

true if the task can continue or false otherwise

maxDuration

public long maxDuration()

Description copied from interface: TimeBudget

The maximum length of time that the task can execute

Specified by:

maxDuration in interface TimeBudget

Returns:

the length of time in milliseconds

elapsed

public Duration elapsed()

Description copied from interface: Budget

The amount of time that has elapsed since the budget was created. This can be used to account for the amount of time it took to run a task. The precision should be withing a few microseconds/milliseconds due to the start time being created along with the budget instance. We do so to avoid the overhead of checking it the next or canContinue methods because they could be part of the hot path for some components.

Specified by:

elapsed in interface Budget

Returns:

The amount of time that has elapsed since the budget was created
