  • Field Details

    • NULL_ACCOUNTABLE

      static final Accountable NULL_ACCOUNTABLE
      An accountable that always returns 0

  • Method Details

    • ramBytesUsed

      long ramBytesUsed()
      Return the memory usage of this object in bytes. Negative values are illegal.

    • getChildResources

      default Collection<Accountable> getChildResources()
      Returns nested resources of this class. The result should be a point-in-time snapshot (to avoid race conditions).
