Module io.helidon.common.concurrency.limits
Package io.helidon.common.concurrency.limits

Interface LimitAlgorithm.Token

Enclosing interface:
LimitAlgorithm
public static interface LimitAlgorithm.Token
When a token is retrieved from LimitAlgorithm.tryAcquire(), one of its methods must be called when the task is over, to release the token back to the pool (such as a permit returned to a Semaphore).

Choice of method to invoke may influence the algorithm used for determining number of available permits.

  • Method Summary

    Modifier and Type
    Method
    Description
    void
    dropped()
    Operation was dropped, for example because it hit a timeout, or was rejected by other limits.
    void
    ignore()
    The operation failed before any meaningful RTT measurement could be made and should be ignored to not introduce an artificially low RTT.
    void
    success()
    Notification that the operation succeeded and internally measured latency should be used as an RTT sample.

  • Method Details

    • dropped

      void dropped()
      Operation was dropped, for example because it hit a timeout, or was rejected by other limits. Loss based Limit implementations will likely do an aggressive reducing in limit when this happens.

    • ignore

      void ignore()
      The operation failed before any meaningful RTT measurement could be made and should be ignored to not introduce an artificially low RTT.

    • success

      void success()
      Notification that the operation succeeded and internally measured latency should be used as an RTT sample.
